Charge issues

[R Bedell]

You have the wrong V/R for the 127. Assuming you are using the older 4 terminal V/R used on the 70/100 series, DON'T use the "L" terminal.

Here is the 127 Charging Circuit. Make sure the wires are connected correctly AND you have a good ground.

when bought they had the 4 term VRs. also a 147 . but same wiring as we know..

the L is empty. just B F and A underside..

i think i found the issue.. ill give hint.. i did put new term post on the SG. nope wasnt shorting.. but i pulled the coils out of the casing of the SG to do the new post.. nope coils are fine inside. no shorts..
might give a hint..

Nothing was said in the original post about you servicing the S/G's.

i learned something new lol... new clue every time you work on them or disconnect them.. they need to be re-polarized.

i think .... that was issue.. i did the short A to battery while running . just touch .. spark done..
seems OK now..
floating 13 to 16.5 sometimes 17. but it isnt running away on the voltage now..

It has always been my understanding that starter/generators, as opposed to generators, do not have to be manually polarized.
When you did what you thought was repolarizing by touching the S/G "A" terminal to battery plus, it is done automatically the first time you hit the starter solenoid as you can see in the wiring diagram.
So, your problem may be solved, but not by "re-polarizing".
By the way, on a 4-lug regulator, the post on the bottom is the equivelent of the "GEN" lug on 3-lug regulators. The "L" lug (or Load) on 4-lug regulators is for providing greater current to high drain loads such as lights or other accessories.

In addition, if you are seeing 16-17 volts and and consider that "isn't running away on the voltage now", how much would you consider to be "running away"?

not sure as the polarizing but it seems to be working. it was my understanding they needed that.. so iam lost there..
run away voltage was goin to 17 plus. hittin 18... within 10 mins of run. it wasnt comming off 17 to 18. also amp gauge peged rite... now its floating all over place. 13 to 16.5, so iam guessing the VR is working .
after touching A to bat. it doesnt do that no more. i just mowed for hour and she ran around the 1st line above 0 . wasnt jumping all over like my other 127 does. seems stable now.

so i have no clue. you say no need to pole it. yet ive read and seen vids to do it. so ill leave that one to the experts. iam far from one thats for sure.

thank you all for the help for sure.. cold bev or hot your choices. say my name they take care of ya lol

edit ps... if iam wrong or doing wrong. pelase tell me so i learn what iam doing here. rebuild a motor is much easier then wiring for me lol ... tho these are pretty simple compared to cars and trucks. hahhaha will new stuff. give me a ole SQ body anyday lol

wow one thing or another... now i have to let off the key to start it..
in start postion crank a few times then let key go and it fires.

i give up lol
