transfered a 200amp hummer alt to my LMTV few years ago. All been good. All the sudden it has stopped charging. Does not reach 28v at bats (or on dash) and does not reach 14v.
Anyone have diagnostic hints?? like which one on this alt. is the excite wire? Figure will need to asses if it is getting 24v. I dont see labeling on anything but the 14v+ on side of regulator.
non related to this issue.. but future question... this alt is temperature sensing; if I understand right, and will dial back output to save itself. Is that correct? Where is the sensor? inside body of the regulator and it senses thru the contact of regulator to the alt. body orrrrrrrr??? wire to a sensor in the alt. orrr? But again.. this is secondary.. primary is checking to see if this one has failed me.
