SH-775 wiring and battery drain

Nessism said......"No load voltage at the stator doesn't mean the thing will make current (I think). At least that what I'm assuming at this point because the charging is poor "

Yes, the no load AC test only has a tiny current (for multimeter) flowing from stator. When stator is doing really work (i.e. pushing out 150 watts + ), you might find it falls flat.

Those who want to wire direct to battery via inline fuse (instead of harness) need to understand that bikes loads now have to all pass thru the 15 amp main fuse (at all times) in suzuki fusebox. Of course, you can add accessory outlets direct from battery to power igadgets, boomboxes, etc.

Something in the first post caught my eye.

All 3 yellow wires to the stator, the inner wire on the other side I wired to the same red (+) feed in the harness that the stock R/R was using and the outer connector on that same side I wired directly to the batter, there is no sense wire on this.

Hopefully you wired it to the NEGATIVE terminal on the battery.

I have a question about installing the SH-775 that I don't think has been addressed. What gage wire is recommended coming out of the regulator/rectifier for the ground and positive? Also any spade connectors better than others? (I was going to try to find copper or brass connectors). I was going to solder and heat shrink the connectors. After plugging in my connectors I was going to fill the cavity with RTV silicone. Recommended or overkill? Thanks Norm

I prefer 14 gauge for those wires.

If you do fill the cavity's, use non-acidic RTV.

Thanks guys, sounds good. I think I got this.

Now I am chasing a no-charging issue with my bike. I installed a 775 about a year ago and connected into the red wire in the harness instead of going directly to the battery and it was working OK. The stator now tests weak at 70 volts at 2 legs and 40 at the other at 5000 rpm. While troubleshooting I tried disconnecting the the 775 from the charging system while leaving the stator connected. I noticed that zero voltage was present at the regulator while the bike was running. Shouldn't there be some voltage even with a weak stator or does the 775 need to be connected to the harness?

".....The stator now tests weak at 70 volts at 2 legs and 40 at the other at 5000 rpm. "

This was open circuit with stator disconected from R/R ? Ok, did you test for voltage from any stator lead to good ground- you should get none.
remember the R/R can't do much if stator has a problem

[1980GS1000E]

Yes, open circuit stator. I am replacing the stator, obviously, and then I will repeat the test. I am thinking that then I should get a good reading with the regulator connected and nothing else?

[rustybronco]

I don't know if it will affect a series R/R by leaving it's output disconnected from the main harness and the stator producing current. Generally it's not a good Idea to do that with conventional R/R and I'd be hesitant to try it on a 775.

Hook it up as it should be connected then measure the battery voltage is the proper way.

[1980GS1000E]

OK, thanks. I will not do that again.

Why do anything else but the standard diagnostic procedures?

Do a Quick Test and report the results.

One must stay creative!

Yes tirelessly creative

The quick test with everything connected net no voltage increase. I was attempting to determine whether the regulator was bad. The battery was at 11 volts. I bought a new yuasa and am waiting for the stator cover gasket.
