Has anyone switched over to one of these instead of relying on the one in the computer?
I used one for about a month. It did what it was bought to do but I did not like it. It pulsed on-off very fast which was noticeable in the head lights and the radio lights at low RPM. I have the entire unit somewhere in a storeroom.
The reason I bought it was to be able to maintain a constant 14+ volts to the battery which was difficult in my model year XJ which is fitted with a battery temperature sensor which would reduce the voltage between 12.8 and 13.5 on a hot South FL summer.

I have this issue too; I get a nice 14v on a cold startup but once it heats up it reduces voltage. I also have a 96; what was your solution? just let it be?
Wondering why you would do this ?
Overcharging/overheating the battery is not good for it. The 96-01 PCM regulates battery charging based on the level of charge, and the heat of the battery as it charges.
I’m running a higher amp alternator for a winch and accessories. The regulator is known to fail under those conditions. Much easier to repair than to replace the PCM.
