Just picked up a 2009 MEP-803A

[craigc]

I have the 803A on a trailer and went over it briefly, I think I lucked out somewhat. Then I dug around in the bottom and found numerous pieces.

- I think all the relays are there and correct. will read a lot more to be sure.
- found it has the fuse mod already, I think
- There were all the parts for the battery hold-downs and both tubs.
- the lug wrench was there and a unused Aux fuel line coiled up in the front door.
- found 2 ground rods ? mounted up under the skid.
- the 3 gauges that can be lit are and have bulbs in them.
- all the filters have 2014 hand written on them, air filter looks brand new.

Anyone know what these are? found them laying in the bottom of the genset.

Those wire items go on the output terminal lugs.

 

[craigc]

Thank you for letting me know, I've been reading everything I can to learn about this equipment.

Actually it's the "Fuse Mod" and yes you have it.
You can tell by the fuse in mounted to the left of the Voltage Regulator.

Looks like a nice unit.

Thanks again, I've edited the first post to correct that. It seems to be ok so far but we'll find out for sure once all the fluids and filters are changed out and a really good going over. I am wondering what is going on with the wires that are pulled from the bundle in the pictures. These are the batteries I'm hoping will work well in this unit[h=1]Duracell AGM Automotive Battery - Group Size 34/78[/h]

 

[craigc]

oops double post please delete. sorry I'm new to this

 

[DieselAddict]

The batteries that seem to fit best are Group 51.

Edit - I can report that Group 24 batteries do not fit and are the same basic dimensions of Group 34.

 

[craigc]

Thanks, I was going to buy them tomorrow so you have saved me a real headache. I'll get group 51

What do those wires do that connect to the output lugs? Mine are missing

 

[kloppk]

I suspect they are there to prevent the nuts from getting lost when they are fully unscrewed from the stud.

A better picture... (click to zoom in)

Nice looking unit.

I will have to look under my skid for a ground rod. My documents had an inventory list saying my unit had a 3 piece rod and 6 AWG cable but I didn't find it.

 

[craigc]

They will be on the right side of the skid facing the panel underneath the top lip of the skid. I saw 2 and there is 2 bolted clamps holding them up.

Howdy,
MEP-802A 5kw generator
The military is currently using Optima Yellowtop 51R batteries x 2 in series for the 24 volt system

MEP-803A 10kw generator
The military is currently using Optima Redtop 34/78 batteries x 2 in series for the 24 volt system

Use whatever battery you want. AGM batteries cost more, but, whatever style you want to buy.

 

[craigc]

Thanks, I had read that but the Optima batteries are not as good as their price would seem. I plan on keeping the genset so I will use a good quality AGM battery that's equivalent to the Optima batteries.

I stuck group 24 marine start batteries in mine. They fit the pans perfect but just barely contact the two unused mount tabs on the block. I put a piece of cardboard between the tabs and batteries but I may pull them out and grind those tabs down a little. They sure spin the heck out of it.

 

[TrailLifeBill]

Very nice genset!! Mine had the 2 ground rod sections on the skid also, but didn't have the driver and couplers. I have a store bought rod, but at some point I think I'd like to pick up an original set.

Thanks I think I got Lucky, I would also like to find the driver and couplers. Have to read and see I I can find the part numbers.

Found the 3 ground rods on mine but no sign of the couplers and cable. Inventory sheet showing my unit had this complete as well as a long auxiliary fuel hose and the bung adapter. It has the hose and adapter but the tube for the adapter is not to be found either.

 

[Triton]

My adapters, ground wire, and hammer are missing as well, others on the site have said they would use them and leave the rods in the ground. Makes sense but I would like to replace them as well.
