That sounds dumb to me, any comments or ideas on that? He says when going 12 volt, to just put in a reg for 12 and you're all set! Can't be that easy! I'm going to change my 50 to 12 later, probly use alt, but may use orig gen if above info is correct. Doesn't seem right to me. :rolleyes:

They have no load except for the ignition and the engine runs at a constant speed most of the time.Its also common practice on old British motorcycles to bump up a 6 volt generator with a regulator change.Again, it works just ok if you have little load and keep the engine reved up.The difference between 12 and 6 volt generators is in the number and guage of the wire windings in the armature and or field coils | | |

Sorry to take over...

#90173 08/05/2002 6:31 PM | Joined: Apr 2002 Posts: 15 Member | | Member Joined: Apr 2002 Posts: 15 | I am not sure where to start...the ammeter stays right on the center line with the engine running regardless of speed. When I put a load on the system (turning on fan blower), the gauge drops.
Does the generator "lose" it's polarity? I just got the truck runnning, and I do not know the condition of the generator. When should I hook up the meter to test the output?
Any idea where I can get brushes, maybe I will just rebuild it.
Any other ideas?
ALL apprecaited.
