I was wonder this while lurking this forum for the last couple of years?
I was thinking that it has to due to the volts? Is this correct? It seems like all the aftermarket alternators I bought for other cars only put out 13.5-13.9 volts out of the box. when I check my rodeo's alternator it is puting out around 14.2 volts. Does the rodeo's pcm need the higher voltage to work?

If the volts are the issue why doesn't the aftermarket put different voltage regulators in that regulate more volts? It seems to me that the rate of return to the aftermarket on this models alternator would be sky high, indicating that the aftermarket is not rebuilding them right?

Any thoughts would be appreciated! Mike
