Not clear if you're using an LED for the generator function (red) 
light.  You're not supposed to use an LED here, but I've never heard an 
explanation why (except that the bulb is part of the generator circuit, 
and may provide some necessary resistance). Anyway, I've run that way 
for a few hours with no issues, but I'll be replacing with a standard 
incandescent bulb before I get my car back on the road.
