Re: Voltage regulator and alternator questions
I was headed towards the mew internaly regulated alternator except the shop said that the old original was a lot heavier duty. They say the early style GM externaly regulated alternators are bulletproof compared to the newer style. The early ones have the power trtansistors pressed into the housing and cool better. The only difference between an externaly regulated and an internaly regulated alternator is where the regulator is.simple as that.
All of the reading I have done on the 1 wire set ups are that they are for simplicity of wiring only. The actual practical value does not stand up to the three wire alternators with the sence wire that tells the alternator what to do. One wires only know to put out a straight voltage and don't kick it up when the demands are great from sources down the line... such as stereos and lights. Madelectric.com or something like that has good info on this stuff.
I am hauling it all back to the shop...............they are pros and I payed for the rebuild so I am sure it will work out.
