    Default MEP 804B Circuit interruptor wont stay closed

    Working on this 804b and when you release the start switch after 6 seconds it stays running but all my instrumentation goes back to zero and my Circuit intereuptor switch wont stay closed. Trying to find the exact troubleshoot for this.. Tested fuse next to the A1 voltage regulator and it was good. I have 11 volts on pin 7 on the S1 switch when i hold the switch in the start position.. I switched the K15 relay and k14 relay to see if that would work, and Nothing has worked so far..

    I would like to test thr volatage regulator but cant remember what terminals to disconnect and try it. I believe it was terminal 1 and 5.. Its been awhile.. Any suggestions or gave a link to the trouble shoot?

    You will want to refer to TM 9-6115-643-24 for troubleshooting and wiring diagrams.
    If you are measuring only 11 volts on S1-7 when it's in the START position then there is certainly a problem.
    Ought to be ~ 24 volts DC then.

    First thing I'd check is to see if the batteries are fully charged...

    I would get the -24 manual out and look up the test procedure.
