i have a 1988 bronco II v8 swap completed a year and a half ago but i left all lighting wiring un-molested
i am experiencing flickering headlights and instrument panel lights (taillights could be also but i can't see those) , not just at idle either i can rev up the engine to 3,000+ rpm and they still flicker.
the alternator is making 14.5volts at idle, and the battery is good and holds 12.5volts when load tested
for diagnostic purposes i ran a wire from one of the instrument panel light sockets straigt to the battery. that gauge lights up without flickering while those still wired to the inst panel lighting are flickering
if i shut off the truck they stop flickering as well
my truck has a huuuuuuge lumpy cam
it sounds to me like something that is vibration related
thanks in advance
