Wheres the regulator on my 93 dodge

[Mudbug]

Anyone tell me where my voltage regulator on my 93 dodge? I thought I read they dont have one its
controled by the computer? is this correct?

Yupp built into the ECM which is under the fender behind the battery. the CPS signals the ECM to charge or not. 92-93 had the EMC and previous years had external regulators

Thanks. So its probably my CPS working. Anyone know cheapest place to get one? seen some on ebay.

there is a thread where some one figured out how to test the CPS, make sure the gap is set right also. there are a bunch of threads on the charging sytems on our trucks here, so deffly read into them and get some ideas

Does the truck have A/C? Simple test is if the A/C compressor kicks on then the CPS is working.

I will have to remember that the next time. Thanks.
