Been working on a guy's 1983 Yamaha Venture for quite a while. Thought I was done, but looks like r/r is bad. Does anyone know if the sh775 would work on this bike? By the way Yamaha put the r/r right above the muffler, think I might try to relocate the new one. terrylee
 
If the Yamaha has the same type system with permanent magnets and shunting the excess to ground it should work fine.

I know there's a Venture forum out there with guys who know more about it.
 
I'll go on a "L"imb and guess it's a field regulated alternator- i.e. brushes and slip rings. The R/R would then have two extra smallish wires feeding the field on the alternator. If so, suspect the brushes especially if the R/R appears to be a Shindengen which yamaha used frequently.

Hang on, Tom, I'm getting ready to cut that limb down. :eek:

My son's previous '83 Venture and his current '86 Venture Royale both have permanent magnet and stator systems, just like the GS.

The Polaris regulator should work just fine.

Thanks guys, thought it might have same stator (has three white wires). Going to double check tests, but everything points to bad r/r. terrylee

It was a short fall. Hopefully, this yamaha stator is larger than the suzuki's, so the SH-775 will get to do more work

Ok, Have couple of spare r/r was going to try on Yamaha venture, just to make sure this is the problem before ordering sh775. The wiring on the venture has two red positive wires, two black negative wires, and brown sense(?) wire, from one plug. And three white wires in separate plug. Just wanted to make sure I could combine positives together, negatives together, and not worry about the sense wire? terrylee
 
Thanks, been on that site but didn't see those. Looks like be ok on hooking reds together and blacks together, looks like they join together right after leaving plug. But not sure about brown wire. Looks to go to fuse box, ignition switch. Maybe it's not a sense wire after all? terrrylee
 
Why are we discussing a Yami r/r issue here? Got an "Other Bikes" forum for that, right? Just sayin' :D
 
Sorry just trying to get alittle advise for a bike I'm working on as a favor to someone without having to join another forum. Don't want to feel like a traitor!:rolleyes: Thought since some folks have more than one kind of bike (or have had) might have some thoughts. Didn't mean to upset anyone! terrylee
 
50/50. It was electrical and concerning the SH-775 so I won't turn you in to the politically correct police.:rolleyes: Besides I had a XJ700X so my second choice is Yamaha, still kicking myself for getting rid of my DT250.

No big deal, just havin' some fun.....
 
Good gravy, you're FINALLY getting that beast out of your garage???? :dancing: Just think, you'll be able to get a '57 Cadillac in that space... :p


Anyhoo, yes, you can combine the double positive and negative leads into one wire of sufficient capacity.

Many Honda R/Rs did this, and I've installed them many times by combining the wires.


You can't just ignore the sense wire -- you have to hook it up to a switched positive or the regulator won't regulate (more precisely, it'll regulate at it's highest voltage, which is usually close to 16 volts). For testing, you can just hook it up to the battery positive, but as I understand it, this arrangement can slowly discharge the battery.

Thanks Brian, your right I can't wait to get that huge thing gone! Will provide me with so much garage space! Thanks for answer on r/r, will try it tomorrow on old working one I have before ordering him a new sh775. Just replaced the old glass fuse box with blade type. Every time I tried to remove a glass fuse, holders fell apart, so had no choice! Hoping that might help with the charging problem if I'm lucky. Volt numbers aren't to far off right now. terrylee
 
Got lucky, new fuse box fixed the problem. Should be out of my garage by Monday! terrylee
