I putzed with it a while tonight and found that the LM will send the PM around 5v in a key on/engine off state, but as soon as the engine is running it stops sending the regulation signal. I can't tell if the actual regulator circuit in the PM works or not as I don't have a handy way to send it the proper regulation signal with the car running. I tried another PM I found in the shed, but the car wouldn't even start with that one.
I also went junkyarding today looking for an external voltage reg and connector. The only thing I came up with was a 4-wire ford regulator off a 78 F150. I couldn't figure out how to adapt it though. I guess I'll buy a new dodge regulator and rig together some sort of connector temporarily until I can find a real one.
