Got all my lights hooked up and working, a full battery charge and the engine at 1/3 engine speed the amp gauge is at 12 amps with no lights on and 4-5 amps with the lights on . is the 12 amps normal ? i am using a cut out . thanks, Ken
Sounds excessive to me. From reading earlier threads, the ammeter should barely show a charge at cruising speeds with the headlights on bright.
Here is a link to a bunch of earlier threads:
Your headlights can evidently be original 21 candlepower or up to repro 50 candlepower.
The tail light is evidently only 5 candlepower.
I have never seen a chart on how much current each light type can draw.
Sounds high. I would adjust the third brush for about zero with lights on at cruise. Some even recommend a slight discharge with lights on at cruise if you don't do much night driving.
Don't know about 21CP and 50CP bulbs, but I tested some 32/32CP bulbs and they drew 8 amps/pair. Can't help with taillight bulbs as I run LED tails. I set my max generator output at 12 amps. But I also use a Fun Projects regulator and highly recommend them.
I moved the third brush last night and in the process the insulator broke. maybe i had it to loose or to tight when i tried to slide the brush. looks like it's made of hard paper. i didn't run the engine after that. a new insulator is on the way from Langs thanks Ken
Hi Ken , New insulator will require new brush holders or maybe you ordered the complete plate. In my case I will try first to drill and tap the old brush holders and use cap screws to hold everything together.
Thanks to all that replied.
John i did not order a complete plate. i will try to reuse brush holders
I just replaced the insulator, using my old brush holder.
