They are separate.
On a 73 the stock regulator and the rectifier are seperate units.
Even if you rewire the bike to simplify the harness you won't need the nylon screws if you use the stock reg and rec.
If you are going to rewire everything, it would be a good time to upgrade from that old, unreliable mechanical reg to a solid state reg. Those mechanical regs work, but not very well. Even new the could over charge the battery if you ran at highway speeds much.
The reg that RG shows is a good one. Using that one you won't need the nylon screws either. The solid state unit turns the rotor on and off quicker than the stock mechanical reg. This will help keep the rotor cooler. Cooler = Last longer.
The rec he shows is much more efficient than the stock one. And don't cost much.
You can probably buy the new parts, hook them up and sell the old parts and pay for the new parts.
I know you just asked about the nylon screws, but using the old parts will let you down sooner or later. I would suggest doing the mods now while your down than have to get stuck somewhere and have the long push home.
there the stock seperate reg and rectifier
thanks for the advice ill probably do the upgrade
Now, I'm confused. Have a 78 with reg rect combo from Mikes XS. Still have the stock stator rotor. Do I need nylon? If so, do I need to replace all four. If not, which ones?
I've been without a bike since I crashed my Gold Wing 14 months ago. I''ve been resurecting this bitch for six months. The old rectifer took a crap 100 miles out. I just want to get a little riding in this season. I can do upgrades in the winter.
Nylon screws not required.
Been going thru the site, and checking on what I've done so far. Found a couple of things I hadn't thought of but it still ain't charging. Spending Saturday at it again. Maybe I'll find it hidden in the wiring.
Have you read this link:
Yes, I have. Found no voltage to the brush but when I tried to go bypass that wire I got a dead short,
Curly's trouble shooting guide is written more for the 80 to 83 years. Since yours is a 78 there are some differences.
He talks about grounding the green wire as a bypass.............OK for the 80 to 83, but wrong for the 70 to 79. For your 78 you need to put battery + voltage on the green wire (outer brush).
It is a 78, but I have an aftermarket solid state reg/rec.
Unfortunately the guide does not differentiate between the 70 to 79 years as compared to the 80 to 83 years. When the guide refers to a solid state rec/reg, it is talking about 80 to 83 years. With a 78, if you still have it wired as per the stock set-up, with the inner brush grounded, then you need to put battery+ on the green wire (outer brush).
That explains a lot. I tried that with a jumper today, but the bike took a stubborn spell, and wouldn't start so I could check results. Will try again tomorrow.
I ran jumper from the red white wire yesterday, and got an acceptable charge till I plugged in the yellow headlight wire. No problem, I'll get another source for the headlight. Question now, is there any problems with this? While testing I forgot to turn off the key for about five minutes, and noticed the ignition hot wire was warm to the touch.
I'm getting ready to chopper wire, and don't want to carry over any problems from where I am now.
I have a 1975 with a pamco 277 rephase ignition on it. From what I have read, I need to use the nylon screws with this reg/rec correct?
Whether or not you need the nylon screw mod has nothing to do with your ignition system. There are two kinds of voltage regulators for the XS650. The early mechanical regulators provided battery on the green wire brush with the other brush grounded. The later models regulator provides a ground on the green wire brush and the other brush goes to switched battery (brown wire). If you are using a late model regulator or an after market regulator that provides a ground on the green wire brush, then you have to isolate the grounded brush with nylon screws and apply brown wire voltage to that brush.
That ad doesn't say what it fits. It looks to be for an 80 up bike. If so then yes it needs the nylon screws to use on a 70-79 bike.
I think they also sell a combo reg/rec that is a direct plug in for the 70-79 bikes. It would have two connecters on it, not just one and would not need the nylon screws.
Here is the data sheet and whatnot:
From what I could tell, I do not need to change out my screws, is this correct?
Well, I'm working through my own charging issues, finally got the bike back after 5 years
First things first: '79 650, Black/Gold edition
Had issues with this bike ever since I bought it in '04, was my daily driver (10 miles round trip) and dealt with charging issues since day 1.
Had to put it away for various reasons in '07, finally got it back out and to a mechanic last month. He said my stator was shorted, so replaced that and I was "good to go."
Well, I took it for a 30 minute ride yesterday, was ok. Then this morning took it on a 15 minute ride, basically died when I got back. Battery was only showing 9 volts, so I'm charging it now so I can go through Curly's/Ggggary's guide (THANKS!)
However, before it was put up in '07 I had a rec/reg installed, which you can see below:
Here's a shot of the brushes:
I'm a little confused, do I need the nylon screws?
I just bought a electrical disaster 77 650 I'm putting the pamco on it but was curious on this nylon screw install. The bike is a 77 but was already switched to the black box so do I still need the screws?
