== External Voltage Regulator for 92-93 models ==

The voltage regulator on the 92-92 trucks is an internal unit inside the control module. If this goes out, you can mount an external voltage regulator like the earlier first gens used.

A bad crankshaft position sensor will also cause your voltage regulator to not charge the altenator. '''You can also get by this by doing the following: '''The two terminals on the alternator for the regulator are interchangable. The alternator is a dumb alternator for an external regulator. The PCM is that regulator normally. The alternator does not care weather it is controlled by the PCM or a regulator. The PCM is not affected by not being hooked to the alternator.

The two terminal regulator has the contacts in the shape of a pyrimid. One terminal is missing. The missing terminal and one other terminal are at the base of the pyrimid.

Ok, hook the two alternator terminals to the two regulator terminals. Does no matter which goes to which. Now run a 12 volt line from an ignition source to the top regulator terminal along with the alternator wire. Thats it except you need a good ground from the alternator to the regulator case. On a second gen get that power from the output of the ASD relay.

A little note on this system. I have doen several of them and helped a few do this change. If you hook the 12 volt up to the wrong regulator terminal, it does fry the regulator. Not much problem, seven bucks gets another one.

Mine has been running this was for a year and over 100,000 miles

The terminals for the regulator can be just the round female terminals that are used for connecters on lights and other places or go to an older junk yard and cut the plug from about any old chrysler product.

Thanks to Haulin In Dixie for the instructions.
