thanks,
i was just reading more on the forums, it sounds like someone 10 yrs ago also had loose alternator belts.

i was also reading that 13.6v was about normal for when the engine is running, at idle or higher rpms. i was also reading that 12.5v was normal for when the engine is off, i was getting 13v, so the small difference made me think the alternator wasn't doing enough, but maybe the battery alone was just reading 13v because i had charged it with a charger the day before and then had been driving it an hr or 2...? i'll take readings again in the morning. even if i'm getting the right voltage reading, i don't think the belts are supposed to be loose.

there's so much discussion about alternators, 55 amp, 65 amp, or even higher alternator upgrades. i'm guessing it's simplest to stick with 65 amp bosch at most, in the case that it is the alternator?

thanks!
