    Default Generator removal question

    Do I have to remove the whole front fender to get my generator out? Even with the panel above the fender removed,I can't access the two inner nuts on the bottom mounting bolts. Can't get to them underneath either because of the shield/splash guard. Am I missing something simple? One would think for service in the field, they would have made these items simple to get at, or folks had little tiny hands back in the 50's.

    Offset box wrenches and sockets. The sucker is REALLY heavy. Be careful.

    Yeah it looks heavy. Got the test adapters today, thanks again. I'm going to run a test on the genny tonight and keep my fingers crossed. I pulled the voltage regulator yesterday and cleaned the contact points and ground cables. After pulling the cover off the VR, it smelled like it had been smoked but put it back on and re polarized the generator, and still no charge. THE CIRCUIT BREAKER POINTS ON THE VOLTAGE REGULATOR don't even close.

    Generator putting out 0.00 on the multimeter. Guess its toast. Looks like I'll be having that rebuilt plus a new solid state voltage regulator $$$$. I would like to talk to the previous owner and find out what he did to kill the charging system on this truck. He told me when I purchased it that it was in good working order after the restoration but had quit charging one day while he was driving it.

    Check the filter capacitor at the bottom of the regulator, maybe it has no continuity. They are old.

    You have the adapter. Full field the generator and see if it doesn't come to life. Follow the procedure in the TM.
    Then check the brushes. The genny is pretty bulletproof.

    ?? Full fielding? I did polarize the generator per the TM and nothing. I didn't see anything "full field'. Is this the same thing.

    It's very durable as stated and basic, open it up to see the brushes and inspect, they are likely the cause, if not just keep looking, a problem with them is often easily seen .

    Edit.
    I need to check the manual to see if it is A circuit or B circuit to tell you how to full field.

    Follow procedure on page 2-40 of the TM.
    Here is a link to the manual if you haven't found it already.

    You need TM9-2320-212-20 for these tests.
