The manual for my 46 says with or without field term grounded, you can touch the gen term to a ground and it should spark if you gen is charging. If no spark from the gen terminal cable, no charge. If it is sparking, it is your battery or Voltage Regulator..or a loose connection somewhere...
It should stay running if the gen is charging. | | | | | Joined: Sep 2000 Posts: 390 Shop Shark | | Shop Shark Joined: Sep 2000 Posts: 390 | gee yuh mean that neat lookin digital thing with the dial and a whole lot anumbers thats hangin in the shop? cuz i aint sure how ta use it.

I heard that you could remove a cable and check alt that way, was not sure about the gen,, probably not a good method with all the computer stuff on the new stuff,,,,no way did I mean to insult your mechanical or electrical skills........regards....Fred

If so, we'd replace (or adjust) the regulator. If the engine runs with the battery cable off and the field terminal grounded, the generator is working.
Did you try polorizing the voltage regulator? Battery to generator? Yeah, you tried that.
