Hey Jim, You mean use the momentary Start/Crank terminal off one of those generic switches to excite the alternator I take it?? The one thats hot ONLY while cranking??
Im not sure how good that would be (if thats your intent) cuz when cranking 1) The battery voltage is reduced 2) The RPM is slow and the alternator may not turn fast enough to ever kick itslef into self excitation.
I dont understand how you mean to make the engine crank withiout use of the momentary start/crank terminal BUTTTTTTT of course thats for a solenoid type of starter arrangement instead of a mechanical push start switch..
I see the ignition terminal (one thats hot to feed coil when ON) as the better source cuz it stays hot to excite the alternator during and until its RPM raises sufficient so shes self excited..... Im afraid if you only applied the external excitation (while cranking at slow RPM) while cranking once it switched off the alternator wouldnt ever become excited unless maybe after a high RPM???????
I know you know this stuff as well and better then myself so Im not sure were on the same page here or that I understand your question??????

Sadly though all his efforts seemed to be a waste of time and money as he still couldn''t get the temperamental old thing to run correctly!! If i said that this was a little frustrating for him that would be "conservative" in fact the problem had reduce
