Hi again Briant, thanks for the updates, heres my response:
- Battery installed: battery cable clamps were different sizes. It appears to be a neg ground.
Probably right, most all Alternators (unless special built) are indeed NEG ground so be sure to connect the battery that way..... .
- Ammeter reads charging when I turn the headlights on.
If when not running a load makes the ammeter swing to + Charge (should be - discharge) and since it was originally POS Ground, the leads likely need swapped. NEXT test is to see if when running its charging ?? If charging battery voltage when running at fast RPM should rise to at least 13 up to 14 or so subject to RPM, alternator and battery. Similar you have to have the ammeter wired correct so it swings + Charge (if alternator is working) but - Discharge as loads are applied The engine appears to be turning in the correct direction based on the fins on the cooling fan. If the battery was reversed, would the starter turn the engine backwards? NOOOOO OOOOO it will still turn the same regardless of battery polarity On to the key/magneto function. I looked more closely at the back of the key switch. There is only one wire connected to it. I think the only purpose of the switch is to ground the magneto to stop ignition. If that is the case, I think I can just disconnect it for now and touch it to the engine block to kill the engine. Is my assumption correct? Typically a Mag can have a simple one wire KILL SWITCH that kills the spark if connected to ground which can be the frame YES assumption correct Youre doing good, you got this John T
