Help me! My 802 is only running on one cylinder. This all started after I pulled the head off and cleaned the valves, their seats and the top of the pistons. The injectors are brand new Onan brand injectors. I keep getting white smoke from one cylinder. For testing I swapped the injectors...

So fired up my 802a tonight after some major overhaul work and the alternator doesn’t appear to be charging? Anywhere to start looking first? Here’s the backstory. I took the head off and cleaned the top of the pistons, heads, and valves. New head gasket. New injectors (the old ones were pretty...

Has anyone ever used any aftermarket fuel injectors in their 802 or 803 and how were they? I keep seeing “Friday Parts” injectors come up for like $40 each. Or I can get genuine Onan injectors for $80 or so. I took my current injectors out of my generator and had them flow tested at a local...

So while tearing into my 802 to replace some leaking fuel hoses, I noticed that the top of the thermostat housing showed signs of leaking right at the hose. Well I took the hose off only to discover that the housing had been corroded away. Now I need a new thermostat housing and thermostat...

So the 802 that I’ve had for a few years as a house backup is in need of some repairs. Fuel tank needs cleaning, rubber fuel lines need replacing, and it seems to have really bad blowby. Pull the dipstick while running and it’s shooting mist at ya. Now I noticed in the -24 that the pistons move...

Cold snap came through with TONS of ice. More than half the city is without power, and out towards the country where I live almost nobody has it. But I got my 802! The problem is one of the rubber fuel return lines coming off the rear injector is oozing fuel. It appears to be dry rotted. It is...

So I’m about to be stationed in Japan, and for those unfamiliar with their electric grid, they use 100V 50Hz power. Now I consider myself above average when it comes to understanding electricity and electronics. I know that most modern electronics with wall wort transformers or built-in...

What faults will the Battle Short switch override? The reason I’m asking is I tried to start my generator with a low fuel fault (don’t ask why, I have good resining) and it wouldn’t even crank. Tried the battle short and it still wouldn’t crank. So of course I had to add fuel to get the...

Fired up my generator and I’m using it to run my house right now, bad weather in the area. I decided to pull the oil dipstick while it was running to check for blowby. I’ve always had some mild blowby but today it was very strong/ hot. I would definitely consider it severe blowby. The...

What is the size and type of wire that is used for the controls on the MEPs? It’s white with some sort of maybe fiberglass or other fabric embedded in it. I’ve seen the stuff on other military machines. Sent from my iPhone using Tapatalk

Hey y’all. Quick question about the overload protection on a 802. How does it work and when? I’ve overloaded my machine several times to the point when it bogs down and the frequency gets really low, the machine is sputtering and puffing smoke. It has never tripped the overload. Sent from my...

So I messed up. I forgot to add stabilizer to the diesel in my 802 when I filled it about 9 months ago. Now the diesel has varnished up and coated the inside of the tank. Well I didn’t discover this until after I had ran the generator for about 3 hours. Now it ran just fine, and still does, but...

First off, the stupidity comes from not checking the oil level before running my unit. It’s on my before start checklist, how dumb can I be? Well I fired up my 802 today for probably the first time in 2 months. I let it run for about 20 minutes to charge up the batteries and just get fluids...

Where have all the 803’s gone? The last month or two there have been very few for sell on the auction websites. My father has been trying to snag one for backup power at his house for about 6 months and hasn’t been successful. The first few times it was his fault as he couldn’t figure out the...

First off I would like to apologize for the can of worms I am about to open up as this has been discussed in depth in other threads. That being said, I have a unique situation. Please read the entire thread as there are many important details regarding my electrical setup. First, I have a...

So I've had my 802 for about a month. I've noticed that if I let it sit for 5-7 days and then go to start it, the starter will get the engine started and just as the engine tries to pick up speed it shuts down and illuminates the low oil pressure fault light. If I try and start it right away it...

So my house receives higher than normal voltage from the power company. Between 125-126 volts depending on which outlet you check and where it is on the property. That is over 250v on what should be 240v service. So, does it really matter? How does this happen? Can it be adjusted? (of course...

Hey Yall! New here and this is my first post. The website looks awesome and there is a lot of good info here. I just brought home my first 802 today from the auction warehouse. This thing is amazing. The outside is a little beat up as expected, but after a quick inspection it appears all fluids...
