Hey guys. Ive been having some alternator issues. When I indicate and whatnot, all the dash lights dim with the indicator. So I thought id have a problem with the battery or alternator. The battery tested out fine, and after havibg the stereo going for a couple hours at the drive ins last night, the car started up without an issue so im pretty sure the battery is fine. When I tested the alternator at the terminals, I got the proper reading of about 14 volts. But when I put the car in diagnostics mode, I only get a reading of 12.5 volts approx. Does anyone know what the problem might be?

I think 12.5v in diag is normal, dont quote me though. You said you did a conversion, what was it exactly?
