mep 003 no power output, disconnected battery while running.

[bchauvette]

All of a sudden my MEP 003 stopped putting out powerAlso No power to the convenient outlet. The set came with a battery disconnect switch. I just realized After many days of searching the TMs that I I may have been disconnecting the battery while running. I've been scouring through the TMs looking for the stuff on servicing the rectifier bridge with no luck. If someone could point me to the TM number and location that would lead me to troubleshooting no power output. I would appreciate it. So the basic question is What are the diagnostic steps when there is no what power output.Sorry for the bad grammar. My stroke has left my brain scrambled. Among other things.

Thank you in advance

have you checked the DC circuit breaker on the control panel???

TM5-6115-585-34 has a section on troubleshoot.
Page 2-9 in the July 1977 version of the TM.

If you have the PDF you can search for... ENGINE RUNS NORMALLY BUT GENERATOR HAS NO OUTPUT

Before you go into the rectifier bridge, lets start at the beginning. Could be simply the S1 start switch. Or something simple.

Will the set start and run correctly? Do you have voltage at the load terminals? The 120 volt outlets are separate from the load terminals. You need to see if there is voltage there also. Does the set volt meter and frequency meter read right? If so, your set puts out power, just need to see why the 120 volt outlet doesn't work.

set starts and runs fine. no voltage at the load terminals, no readings on the freq meter or volt meter

thank you for the tm and page number. With all the searching I've done already I must have searched that already I will certainly try again wish me luck

 

[bchauvette]

yes pulled it out and pushed it incouple of times.

How about the convenience outlets... you have power at those?

 

[doghead]

The first sentence in the first post said he had no power at the convenience outlets.

 

[Guyfang]

Lets start easy. Do you have 24 volts on pin 27, of the S1 Start switch, when holding the S1 in the START position?

Also, after checking Guy's start the easy diagnostics...have you checked the F1 (alternator fuse) and are you able to cycle/exercise the AC Voltage Reconnect switch?
