EVO charging system question?
I have a 93 FXR, and I bought a HD engine guard mounted fog lamp kit,
the instructions say they take 9 amps of current from the electrical
system and may overload the charging system.
My question is how much "reserve" does this model have?
I want to use these as running lights and leave them on when riding
as the FXR has the small headlight and is hard for oncoming traffic to
see.
These lights have 55 watt bulbs (2) total, would smaller bulbs be an
option?
Thanks

If you want to figure out how much you're using use the simple electrical formula
amps = watts / volts/ That should give you an idea how much you're currently using. Allow some for your ignition and I'd try to stay below about 80% of current capacity just to keep your syste=m from running at full capacity all the time.

I really wouldn't say never a problem. You do have a 32 amp system, however that is at 2000 to 2500 rpm. At idle, the charging output drops significantly. You may see a slight discharge at idle, especially with the brake light on. Just keep that in mind in town around stop and go traffic.

If you have any problems with the 55w bulbs go to 30 w.......Thats what my running lights are and i have no problems with my system,even at idle
