Well I followed the procedure in the Haynes manual, and the battery is not getting the volts it should. It's a little lower at idle then when turned off, but it should be a couple volts higher. So either the alternator is not producing the power or it's not getting to the battery. Is there any way to rule out that the voltage regulator without replacing it with a new one?

From the description removing the alternator doesn't seem that hard. Loosen 2 bolts, move it around a little, and unplug the wires going to it. Is it much harder or very time consuming in reality? Is tightening the dual belts running the alternator a pain after re-installation? Thanks for the replies and keep them coming.
