Mep-804a issue

[Clinton2292]

Hello new to the forum . I’ll start by saying thanks for having me. I recently purchased a mep-804a at auction well it has some issues I’m hoping I can get some advice on. It has no power to the front panel at all anywhere it will turn over by the switch in the engine bay. Upon further inspection there are some wires burned off of what looks to be a resistor bank in the left upper corner behind the control panel on the back wall. I don’t have a pic of the actual gen it’s at my dads house currently in his barn until I figure out my next move with it I did get a pic off the web of the part in question. And advice of what I should do moving forward would be great

Really could use some advice thanks guys

Have you downloaded the -24 TM for your set? At the end of it are the schematics to help with troubleshooting your set. Also the TM has troubleshooting steps for situations such as No Crank.
A good picture of your resistor panel would be of help too.

I will get the manuals for sure and some pics I was hoping to find out what exactly those resistors are for thank you

Thank you I’m not sure we’re to find the manual I read a post there in this forum but I’m not that computer savvy

The Technical Manuals (TMs) are located in the TM section of this forum.
Here is a link to download the manuals for the 804 ---> MEP-804 TMs
It has the TMs for the Generator and TMs for the engines.
Generally TM's ending in -10 are the Operator TMs, -24 are the Maintenance TMs and -24P are the parts TMs.

The table I posted is from the -24 TM. Schematics are located at the end of it.

Here is the schematic of the resistor assembly from the -24 TM

Truly, a picture would help a lot. Then you/we can see what needs to be replaced. AND, it might help figure out what happened.

Have not been over to get pictures I really just wonder what they do they are labeled sync light resistors if there just for sync generators together then I really don’t care about that

If something caused the components to burn up, then its always possible that it can happen again, if you do not find the cause and properly repair it.

Yes, that much is obvious, but if it’s something to do with syncing two generators together, and it will never be used again then I would rather not just worry about it
