Stupid Wiring Question From A Dumb Guy

    Will someone please identify the terminals of the voltage regulator as found on the wiring diagram for an
    F 134 CJ5 1962. My regulator is configured differently (photo).
    Also the terminals on the generator have no markings. A little help there will also be appreciated.
    Thank you very much.

    On your generator you will have one stud on the housing that doesn't have an insulator. That will be the ground. You will have a bigger stud than the other which will be the Bat (larger stud) and the other one is Fld. As for the regulator we will need a part number or it will be marked on the tabs which you should see after removing a wire from the tab.

    The regulator is marked. It is the one from the wiring diagram that I would like labeled.
    Is the larger stud on the generator also the Alt stud?

    The regulator terminals will be stamped "Batt", (battery), "Fld" (Field) & Arm (armature). I can see the BAT hiding under the top terminal in your pic.

    Thank you
    Maybe I can put this thing together now.

    forgot to add this
    Whenever a generator or a generator regulator is tested, repaired, or replaced, the generator must be polarized. If this is not done, the generator may be damaged and the regulator contacts burned. Reversed polarity will discharge the battery - or damage it.

    There are two types of generator and electromechanical voltage regulator combinations used with DC generators.

    In an "A Circuit" system, the field is grounded through the regulator. "A Circuit" systems are found in most Ford and GM vehicles.

    Most Chrysler vehicles had a "B Circuit" system which was grounded internally through the generator.

    To polarize an "A Circuit" system, connect the FIELD, ARMATURE, and BATTERY leads to the regulator. Connect the battery. Then, momentarily connect a jumper wire between the ARMATURE terminal and the BATTERY terminal at the regulator.

    To polarize a "B Circuit" system, connect the FIELD, and ARMATURE leads to the regulator. Connect the battery. Then, just before installing the BATTERY lead, momentarily touch it to the ARMATURE lead terminal.

    will do BTW What kind did Willys use on the CJ5 ?
    Thanks

    the only stupid question is the one that wasn't asked.

    Willys use the "A" circuit, field is grounded through the regulator as in my diagram above.

    John, don't worry about it. I have worked electrical for over 40 years now -- AC, DC, High Voltage (up to 230,000 volts), Low Voltage (fractions of a volt) High Current (upwards of 100,000 amps, and Low Current (down to nanoamps), etc. and there are times when I have to stop and scratch my head, or whatever, and figure it out. As Tesla, who understood electricity on an esoteric level, once said, "It's electricity. You have to make concessions". Possibly one of the smartest sayings ever uttered...
