Mep 803

[kevin66]

Finally had some time to do a little more testing on k20 oil pressure relay pins 7&4 are reading closed with battery disconnect all others are reading correctly. They are all reading correctly with engine running. Really appreciate the help.

Are you sure it's the relay and not a wiring issue?

 

[kevin66]

I have been going through the wires so far only found 1 and that was on oil pressure gauge. Will continue checking all the wires. Thanks

The generator is now working and putting out power to the output lugs. But will trip overload when putting 10 kw load on it. Is there anything that needs to be changed when swapping a 802 electrical panel to a 803 everything looks to be the same not sure if I'm missing something.

When you say "electrical panel" do you mean the entire cube containing the gauges, VR, relays, K1 contactor, current transformer, etc?

Only the front half

Are you dumping 10k onto it, or working up to it? Does it hold lesser loads properly? Any change in RPM or engine difference? Any black bits being spit out of the muffler?

It does hold 6500k with our any problem it is when I start going over that. Small change in rpms that l adjusted for. The engine doesn't spit out much of any black bits. I have let it run for several hours at 5k without an issue

Well if you just got this going I suggest putting a high quality fuel additive in the mix like seafoam and run it for an hour or two at the highest wattage you know it holds. Then, incrementally add load as you can until you get upwards of rated power. The overload fault could be one of corrosion in contacts in the cube... but if you have never seen this pull rated load, you need to get it up to working temp and see if the fuel can start to dissolve fuel system and combustion chamber FOD and see if you can start working your way up to where its supposed to be. It can take hours to do this properly, if there are no other issues at work.

If you swapped included the current transformer (CT) then you'll get those "overload" faults.
The number of turns of wire thru the CT's is different for an 802 and an 803.

I dump an entire can into a tank on either an 802 or 803... its overkill, but its cheap enough that Id rather it just work.

If you look back up, I think he answered your question but in the quotation. I think it says he swapped only the front half (so would have retained stock CT, etc).

 

[kloppk]

I just wanted to be sure he didn't swap the back half.

@kevin66
1) What do you have your Phase/Voltage reconnect switch set to?
2) How do your have your loads connected to the lugs? How much load and across which lugs?

I will try that next. It will hold 10k for a minute or so before the overload fault.

You might want to invest in a couple milkhouse heaters. They range up to 1500w for under $40 each. You can plug them into your home and turn them on as needed to add more load. Easy, cheap load banking.

Have am-vm set at 1p l-1 & l-3 and set for110-240 single phase. This is the first one I have had that been a pain in the butt but definitely a good learning experience

 

[kevin66]

It is holding around 7200k without tripping overload so I will let it run there for a few hours did add cleaner to tank already. I also have a 802 that I'm in need of a couple of injector pumps if any one has a couple to sell.

Used ones (and the grey market ones you see on ebay) are a real crapshoot. I would go new. These guys can help: https://www.sleeman-hawken.com

Why do you think you need new metering pumps? Have you tried soaking them in carb cleaner for a few days?

What iis the "front half"? Show us a picture. Or drawing.

The fun of semantics with MEPs!
