voltage regulator on 1990 Dodge Ram Van B250

where is the voltage regulator located

Asked by for the 1990 Dodge Ram Van B250
They are generally part of the alternator, is that what you found with yours? Were you able to replace it separately or is it integrated into the alternator?

It is separate, the regulator is a silver box like bolted up just behind where the hood lifts up. If you are looking at the oil dipstick mine is above that (bolted to the top).
It has wires that connect to it in a triangle type shape (but only 2 wires go in).

Hope that helps
The repair manual that I have, saids that it is located in the SECM -aka- computer.
i have a 91 van the computer regulats the voltage in it but im not sure its the same in a 1990
External voltage regulators were not installed after the vans moved to fuel injection- 1987 would be the last year for the external regulator.
The voltage Regulator in a 1990 Dodge Ram B 250 5.9 liter cargo van is inside the ECM unit.
