Correct.
Since writing this, I bought (to much money) a 200 Amp Alternator and it is worse. Also spiratic and the needle jumps up in volts as soon as the rpm's go up when starting to drive although, it doesn't read as high as the first new alternator which is 105 amps. When engine is warm, In idle, stopped and in drive, is when it gives off the worst readings. all plays out on the dashboard volt meter. With multimeter everything is normal. Could it be a ground under the dash? And how could the higher Amp Alt be worse than the stock Alt? Clearly not clear.
Any thoughts? One quick note, other than this, the truck works fine.
