I need to replace my existing alternator, so I called a shop here in Orange County that specializes in building alternators/genators for all types of vehicles, even commercial trucks. He highly advised AGAINST the 1-wire alternators (especially the high-output ones) for a whole host of reasons. For true reliability he recommended that I stick to an internally regulated factory-style alternator that puts out 75-80 amps AT MOST. For cost savings, he even recommended that I buy one from an autoparts store instead of buying a "custom" one from him (even though I told him I was willing to pay more.) So, I'm looking for any opinions or experiences that might contradict this guys rec's. He sounded honest and wasn't trying to sell me anything. I'm stumped.
