you probably know more about it than me
Yeah, he does @pokefun
The 12V (nominal) is produced by the battery, that doesn't change (as the revs rise, the reg/rec keeps the voltage where it should be), so as Motorbreath says, the two variables are the current and the resistance - a dodgy/corroded connection increases the resistance, so the current drops. With a lower current, the power equation, P = I*V shows that the power also drops, with less power, you've got less potential for heat.

yeah i see what you're saying but if there's more load caused by a dodgy connection or just an increase in load like by heated grips or something like that would the alternator not produce more current to compensate for the increased resistance?
