SH-775 wiring and battery drain

[posplayr]

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.

With an expert diagnosis you should be able to figure out with little uncertainty what is wrong when doing the Quick test. So what is wrong?

The problem is no charging and a low battery from running it that way. I hook up to a tender when it's parked. I don't know whether the stator is the whole problem or just part of it. Once I replace it I can rule it out.

Actually those are symptoms

Looking in my factory Kawasaki KZ750 service manual and the R/R power output wire is connected directly to the battery (via the starter solenoid). No fuse in between. The harness is then fed from the battery, passing through fused feeds. I'm in the process of modding the wiring for a SH-775 and need to decide what's best soon. It's interesting to see so much variation between the ways different companies wired these old bikes.

I am considering wiring straight to the battery with a fuse. Seems simpler to me.

three bikes: output from r/r s are all direct to battery....via the post on the solenoid. It never occurred to me there is another way....
I am not sure what good a fuse will do except to isolate the charging system easily for testing purposes,but I can't see any harm in it either, apart from another possibility for connection corrosion.

I can only hope nobody is convinced to follow what you guys are doing.

1980CS1000E I used the original stator when I changed to my Compu-Fire despite warnings that the stator color indicated it would fail. It ran perfectly for one year, then failed. Replaced the stator and everything was fine again. I had initially wired to the stock harness feed. I changed it to direct battery feed through a fuse and charging was definitely better with less dimming of the headlight at idle.

There's lots of nobodys,apparently! Into the harness is the direct route to get juice to whatever needs it-why detour thru battery ?

Again.......... It is probably over nobodies head, but maybe not everybody

I did a side by side compare of the OEM R/R to battery wiring and a comparison to the "popular" way people hook up new R/R and go "direct to the battery". I'm making some assumptions here as I think people normally only add one additional inline fuse. So with that here is a side by side compare.

Bakalorz has also brought up the issue of the high speed current switching that goes on depending upon whether the R/R is sourcing current or not. What that means is when the R/R is not sourcing current it is identical to the condition that I show with engine off so that point is considered in this analysis. The average currents (as measured) remain unchanged as they take the current switching into account.

Bottom line is to stick to the way Suzuki designed it in the first place. This is something they did get right.

I am electrically challenged, I guess. I really can't get everything in that diagram. I am not sure what the arrows indicate. It just looks as if there is an additional fuse added from the battery to the r/r. I want to connect it the best and most reliable way.

The analysis is comparing the current flow from and to the three components ( r/r, battery, and electrical system) the summary does a side by side compare of the differences and conclusions of the two configurations. The issue I understanding the summary and conclusions has little to so with v=IR.

I even state explicitly don't change the wAy Suzuki did it.

I wonder if I should delete this thread before Jim goes thru the roof and types something to get himself banned

[1980GS1000E]

I'll just hook it up to the red wire in the harness. I haven't changed anything except removing the headlight loop and the 775 r/r. we shall see if the new stator fixes the no-charge issue.

I'm getting close to banning myself.
