Code 41 Voltage Reg is in which module........
86 Plymouth Reliant 2.2, A/T. Which location for which module that regulates voltage? The one in the engine bay or the one behind the right kick panel?? I have code 41 coming up, I replaced the alternator and still have code 41. This happened to us before but a senior moment prevents me from recalling which to replace. Help is appreciated.

Re: Code 41 Voltage Reg is in which module........
It's my understanding that the logic module senses the charging system voltage, then signals the power module to control the alternator field. I'm not sure which is your problem? My info shows the alternator doesn't have an internal regulator?
The two green wires on the back of the alternator, should be hot with the engine running? On one of thses wires there should be a dc pulse, with the engine running. If you have a dmm with a tach setting--dwell setting--frequency counter, any of these will react to a dc pulse, anything? If your not getting voltage to those terminals, I don't believe the problem is the alternator or regulator circuitry. The power module is under the hood, but I can't say that is your problem.

Replaced the power(?) module in the engine bay, next to battery & the problem is solved.

Re: Code 41 Voltage Reg is in which module........
no spark, hmm, two things right off the bat to suspect,most common is the pickup plate in the distributor under the rotor,no real way to test it if you don't have a scanner,& can monitor it while cranking, the other is possibly the dist. rotor has a very small hole burned in it and is taking the spark directly to the dist. shaft. Easy way to check it is to remove the dist. cap,then remove the coil wire from the cap. hold the end of the wire approx 1/8" away from a good ground,making sure you are insulated from it,while someone else cranks the engine,if there is spark, repeat the cranking while holding the end of the wire dirctly over the top of the rotor,if itsparks to the rotor it has burned through.
You may even have a bad crank sensor, or coil. Martola
