NEW ISSUE Post #29
Alright so I know this topic comes up alot (because i've read just about every thread on it trying to self diagnose my issue lol)
Alright so this is going to be pretty much a narrative, for those that stick with me I want to go ahead and thank you now. I'm at wits end here. hopefully you guys can fill me in on what i'm obviously over looking.
Little back ground Bike is an 80 xs650 "running motor" was full of water when i went to change gaskets, so went ahead and rebuilt it got it rephased by hugh and all is well there.
Issue at hand
Everything is mocked up and i've made a mock harness so i can just make sure all is well before I strip and paint. I used this diagram no lights wired in yet just very basic get it running/charging wiring. Also this pic. shows a brown wire ofcourse Hughs PMA only has a red green and three yellows so instead of that brown wire mine is the red.
Bike is not wanting to run for more than 10-15 sec. and is terribly hard to even get to start. Almost every time I kick it I here the bump bump of both cylinders firing but apparently not enough to make her run. Carbs are clean and when it dies it seems to die from loosing spark instant kill not like a running out of fuel die. My educated guess is that its loosing spark seeing as I was attempting to run a capacitor I figured maybe the PMA isnt supplying enough power through my kicks (fresh built motor is a PAIN to kick over so much) That to me cleared up both my issues in my head. Not getting hot spark and pma possibly not charging capacitor causing the die once it finally did start. So I hooked up a fresh battery out of another bike of mine. Battery is in great condition and shows 12.96 volts when checked with a multi meter. Figured it would run the bike fine and i could hook the pma back in later to make sure it was charging. Well it's not it is doing the exact same thing and actually hasnt started at all since putting the battery to it instead of the capacitor. Just the same bump bump of each cylinder firing. So hopefully someone can point out a mistake ive mead. I am attaching photos of where my pamco timing is setup and how the coils are wired.
Short and sweet
*Seem to be getting weak spark using capacitor and battery
*motor is grounded straight to bare frame
*getting fuel
*plugs show a little rich but not bad (possibly due to so much kicking and no fire up)
* Basic wiring hot to pamco and coil down to battery (kill switch and 7.5amp fuse in between) pamco grounded and green wire hooked to coil. battery grounded to frame (PMA not currently hooked in)
*fresh known good battery
*motor ran a couple times for 10-15 sec. lots of kicking not much action
Heres a pic of where my pamco is set
Coil Wiring
another shot
Thank you guys for holding on with me through that. I'm hoping some one will be able to shed a little light on something dumb ive done. I tried to be as descriptive as possible but you guys may still need more info please let me know. I know there are alot of really smart guys on this bored and i appreciate all the help i can get. I've kicked this thing so much my foot may never be the same and i've already bent my kickstart lever haha
Apparently I did not tag this correctly I started a new thread in the electrical section but i guess i needed to tag it as such. Sorry for that. If a mod could please put this over there that would be much appreciated i dont mean to clog up the General discussion sub-forum. Thanks!
