Where is the voltage regulator located in my vehicle?

(1998 Dodge Ram Van 2500)
in Elkhart, IN on April 29, 2009
My vehicle is registering no voltage
on the dashboard. When I had the alternator checked out, it registered ok. I've been told 2 things, go ahead and change out the alternator and that should take care of the problem or have the voltage regulator changed out. We don't know where the voltage regulator is located.

is part of the Engine Management Computer (box) - if it is faulty it needs to be replaced... however, your description says the dash gauge is zero with every thing else working and no trouble found with the alternator - then it should be the connection(s)/wires from the computer to the dash gauge. The computer sends the signal of "good"voltage; but the gauge says zero; also the gauge itself could be bad. Test gauge with voltmeter attached to the connections of the gauge...

The Electronic Voltage Regulator (EVR) is not a separate component. The voltage regulator is actually a voltage regulating circuit located within the Powertrain Control Module (PCM). The EVR is not serviced separately. If replacement is necessary, the PCM must be replaced.
