What car and did you replace the alt B+ to battery cable or overlay?

Stock alternators (well at least the ones I deal with) are rated at a certain temperature and speed (80 °F and 6000 alt rpm are common) and tested according to an SAE test method. They can produce slightly higher current, but generally at higher temperatures they will produce lower current. My...

An alternator is only so efficient, 50 - 70% depending your model. Assume that your alternator is 50% efficient, rated at 100A. For the alternator to produce 50A @ 14v, it is producing that same amount of heat (efficiency loss mainly produces heat but there are mechanical losses also). So 50A...

What bub is saying is all true. I will add a couple notes. Putting in a larger battery will only help if the alternator cannot keep up with the system voltage that the amps are continuously pulling for a set timeframe. BUT, after a short period of time, the larger battery will be no better...
