New here, need some help!!

You need to ask questions rather than decide to do something and post. Those diagrams made up like the one you posted have been bastidized from the original 81 simplified diagram. So many have been made up that are wrong, confusing, and just bad drawing, then posted and then others come along thinking they can be used for a reference........

That diagram has a pamco ignition. a pamco needs to be isolated with a 7.5 fuse.

You have points..........pamcos are no longer made..............so the 7.5 fuse isn't needed

The diagram NJ posted is what you should be working off............the modules for points and factory TCI,(electronic), ignitions can be swapped in to suit the 2 different systems.

here is another set of simplified diagrams that are broken down into their separate systems, to make it easy to use whatever is wanted.

This also has a pamco ignition so that needs to be swapped for what ever system you are going to use
....Main Circuit.....................................Charging......................................Ignition......................................Head-light/Tail-light....................brake-light

not sure if this helps BUT
(I just basically rebuild an 81xs 650) first thing I did was
but a new wiring harness from mikes XS for 60 bucks.
that way the basics were out of the way, (lights blinker coil tail lights etc)
(and its pretty much plug n play) and I moved on from there
 
I don't have turn signals on the bike..not sure if they were ever there to be honest. But I don't have points, I have the gen 2 mikexs electronic ignition, along with capacitor, regulator, PMA. There was points on the bike when I first bought it but since it has all the components for the electric setup I bought a mikexs electronic ignition. The tci and everything is gone from the bike. Should I be buying and reinstalling the points, tci, etc like those diagrams? And sorry, I'm new here I'm not meaning to confuse other people looking for help.. I just was showing the diagrams that match my bike the most and would be the easiest set up for how my bike is set up right now you know? I didn't mean to imply that's the right way and I guess I should have added a question to it more, I meant to ASK if those are good enough to follow? And I know pamco was pamcopete that's no longer made but isn't mikexs electronic ignition basically a pamco just not named that?? Or am I misunderstanding pamco and electronic ignition? Again, I'm not trying to mess up the forum I don't know how to post correctly on here this is just my first one so please lemme know what I can do right so I'm not annoying people haha
 
Also if your talking about the drawing on cardboard that's made up yeah but that's how my bike is wired I don't want anyone following that or thinking that's right lol. But if you meant the ones from online I posted those were from a few different websites I found. I forgot to add this into my previous post
 
I will! And I don't mind showing you even with it being a mess because it might be a mess now but one day it will be great one done! Lol and couldn't do it without you guys helping lol
 
Okay I'm going to post different ones because I don't know how to add pics and write under them etc lol. But here is the overall points and new electronic ignition. None is hooked up right now I disconnected everything lol.

Okay so here's the deal with the next photos. The collage I have a screw driver pointed to the orange wire, it goes from (what used to be two coils and it was split and wired to both until I cut it off of them) and leads down to a yellow wire with 30A fuse, connecting to acc key. This is the wire that I don't understand. Then I labled the pics to make it easier for me to explain ha. This is ALL original wiring except for my new regulator, I attached it to where the previous regulator wires were and then the alternator (idk if the prev reg wires were even right now that I see how crazy the bike is wired. Pic 1 is the kill and lights. The kill switch has three yellow wires, and one is to the taillight, one to headlighr switch, and then one to a 30 amp fuse that (kind of) connects to the orange wire as in they are both attached to the ignition. So 60amps of fuses are both on the acc. Then the headlight switch is literally just the headlight wires(Blue and green) and the one that connects to kill switch. Pic 2 is literally what I pulled out of that box lol. The capacitor and reg is new, I just attached it how they had it on the old ones. Literally when I say it was all in that box it literally was all shoved in that box so that is not my fault it's such a mess ha. Pic 3 just shows exactly where everything is since its so messy lol. Pic 4just highlights the two 30 fuses. I just wanted to try to be specific with the pics. Does anybody know when in the crap is going on with this? Or can tell me if maybe I should just rewire it or whatnot? Thanks guys!

This is a bike style I like its i personal and it is well ..ehhh " Not Mint "
ON top of that it appears to have some flake on the tank.
This is the type of bikes my friends had Early 70 ies.
It can be a challenge but here we can come in.

I have no experience with the parts you have .But someone else have here
Now
The cardboard schematic needs to be clarified redrawn there is fex a wire not connected from coil to igblty or something
Please draw a better schematic one and write in the Queens English as the UK Gentlemen says what things mean fex igblty

Please provide a list of what parts that is connected and are going to be used

Is there spark on Both sides but weak ..?? .. I might be in the garage myself ..but I will check in here sooner or later
 
Skull, do I not know what a tci is? Isn't it ignition.? Sorry, I am just confused. I have the electronic ignition and don't want points or tci just because electronic is easier in my opinion.sorry Jan it was such a rough drawing because honestly it's such a mess. Do you mean there's not supposed to be a wire from the capacitor (bty) and ignition (ig) to the coil? I will have to try to draw a better schematic when I get a moment, it's really hard because all of the wires are yellow basically and go all over the place lol. As for parts,

It's electronic ignition with a PMA, regulator, capacitor. I have a "D&M" PMA which I can't find anywhere online, have you or anyone heard of it? Have no clue about any serial numbers etc it's not listed on it, and I'm not sure if maybe it's super old and needs replaced too..

But yes it isn't in the best of condition! I'm going to repaint it and clean all the crud off of it once I get it running and then it'll definitely be beautiful lol.

As for spark yeah it's weak in my opinion, but there nonetheless, although I don't know why there's spark because of how the wiring is....
 
Sho' enuff that wiring's a mess and hopefully you got a title with that bike......
Wondering if Daddy G (or anyone else) ever built a PMA loom or could point one out to follow for a chopper...you out there Rich?

On an aside......
Anyone ever read Twain's short story about Horace Greeley's letter to a young man? Jan_P's post at #30 brought it to mind, and no disrespect to Jan, glad to have him on board (I'll note here that one of me ancestors came over from Gothenburg in 1639, we could be kin).
 
Thankfully there was a title! So I know for sure the frame is 75. The engine definitely is not from matching the serial numbers of it though. Which makes me wonder this: did the guy who sold it to me botch it by treating it like a 75 engine, or did the guy before him wire it awful and sell it saying it only needed one thing, which made the next guy buy a few parts and say wtf never mind lol.. but either way, yes the wiring is crazy!! Haha I have never seen anything wired so nuts. But I have not read Twain's short story. However if your talking about style, jans post did remind me of a poem style for some reason? When you say built a PMA loom, what do you mean, replace PMA, rebuild PMA, or rewire the whole bike with the PMA? I'm sorry I'm not sure
 
Loom is another term for wiring harness.
Daddy G makes simple looms for sale from time to time, he also has built some choppers......mebbe with PMA's, who knows? May be able to use what you have in parts, just get the loom for tying it in.....on a hardtail.
Twains story is in misunderstanding a written letter and it's implications......funny.
 
Unless MIkesXS sells a chopper wiring loom, buying a full loom for an 81 is wasting money, it wont fit your frame.

Skull is spot on with that. There is not much on your bike that a stock harness to hook up to . Non stock ignition ,charging system and key lock non of which will hook directly to a stock loom.

First. of all I would follow Pete's advice and isolate the ignition from the rest of the electrical system until the bugs are shook out.

Getting a PMA / capacitor system to work properly is a challenge so I would get what here in Texas is known as a feeder battery (small SLA 12v battery) to test with.

The bones you have are just fine. The key switch for example is a classic that fits the era and style of the bike and provides a good solution to the light on all the time problem. There are 4 terminals on the switch. in position 1 it provides power to the acc terminal. In position 2 it provides power to the acc post and to the Ign post.
It can be wired so pos 1 is day time with power to the pamco comes from the acc post. Headlight and tail light powered by the ign post when in position 2 . Backwards from what GM designed but works well and have seen those switches on bikes for years.

The are only 3 wires on the Pamco. Get those hooked up properly and get the bike to run. Then you can move on to charging and lighting.
 
Okay so I will invest in the small 12v battery! As for the key, there are only three terminals on the switch. One says acc, batt, and I can't remember the third one as I'm not home I'm sorry! With a capacitor, headlights don't come on in anyway until the engine is running right? It's not like a battery where as I can put it just to acc and turn lights/etc on and off freely without running? But okay i thought the loom meant harness but wasn't exactly sure, and yes I noticed all of them from mikesxs aren't compatible with how the bike is set up. I don't have all the plugs etc like the harness does, not sure if it ever did before though. overall, are you thinking I should to stick with what I have and leave the wiring alone, or rewire the bike and still use the same key ignition,switch,etc?
 
I suggest you get all the switches mounted in their final positions then proceed with the rewiring. As suggested by Team Junk above, use a small battery to get the ignition side of the wiring working. This means you can forget about wiring in the PMA/Lights/Capacitor until you have a running engine. Once you achieve this then complete the rest of the wiring. 650Skull has kindly included an ignition wiring diagram (PAMCO + Coil at Top, Ignition + Kill Switch to Left, Battery + Fuse Box to Right) in Entry #21 with the basics to get a battery only system working. Just make sure you have a good Ground Terminal on the bike frame.

Let us know how you are progressing - Best of Luck.
 
Thanks guys! Will the switch back to capacitor be easy or honestly should I just leave it battery? It came as a capacitor I'm not opposed to leaving it battery if the pamco/PMA/etc still works with a battery. I also personally think batteries are a bit easier when troubleshooting and fixing etc. But I don't want to mess up the system on it if I incorporate a battery instead of capacitor ha. Also j will remove all the wires place where I want whatever to go and then redo it from there! 650skulls diagram seems to be a more complex version of the one I had posted towards the beginning, I'm familiar with wiring diagrams and wiring but definitely not the level of that just yet, think I might start with my super simplified to get it started and then incorporate 650skulls so I don't get completely lost during the wiring.
