Charging system/ starting woes

Hi,

I found these on some guy's website.

Stator Test

Regulator/Rectifier Diode Test


Thank you for your indulgence,

Yes, I read that and did the tests, much more informative than the 'stator papers' The tests in the stator papers never worked for me. All R&R's (good or bad) tested bad with the stator papers tests

He said it was a garage station booster- sorta like a short circuit device on wheels!

Well it was either sit there for several hours to let the bike cool down, or get the guy to use his booster
I think he said he was feeding it 40A to get it to start.

My standard size Shumacher has a starting mode of (supposedly) 40 Amps. It is what I would call a hand-held vs. one on a roll cart.

Stator tested good, 50VAC and even at 3k rpm and 60VAC at 4k rpm.
I will get my new R&R installed on my days off.
The question I asked before is that this one has two red and two green wires. Do I connect them together then to the battery. Or just tape one off Does it matter?
There are 2 red, 2 green, 3 yellow, one black (sense)

The Stator Papers has a couple of active tests that are very informative (like the voltage drop between the r/r output and the battery positive). But I put those together as "quick and dirty" tests to aid in troubleshooting. I have found that almost any test will tell you if you have a bad part but won't necessarily prove that you have a good part.

The one he used was on like a dolly, he only used 40a, but I am sure it went much higher.

The 2 red wires are the output voltage. I would splice them together, put a 20A fuse inline, and connect to the battery. the 2 green wires are your grounds. Depending on your outlook, you could run 1 to the battery and 1 to a frame ground. Or run both to a common ground, dealer's choice.
Multiple wires decrease heat and increase efficiency, so I would certainly connect them all.

I wired in the new R&R, soldered most all the connections. One neg wire to frame the other to batt + . I still have a flaky charging system. The stator wires get warm when running. I am using spade connectors, and there are a couple butt connectors inline as well.
I am getting tired of it, so I am going to solder the wires in now. I tested the stator and it checks out fine. I think the heat created in the wires is because of resistance in the wires caused by bad connections.

I gave up on spade conections and just solder mine in too.

Yup spades are no good, every spade that I had was running hot/warm.
I soldered every connection i could find in the charging system.
