Really nice job. I can't believe how much love you put into an 831. Give everything else a good double-check before you're done, especially the cooling fans. The inverter cooling fan should turn on with the switch in the run position without engine running-- you should hear it. The other two...

I'm a mechanical contractor specializing in refrigeration. Burning refrigerant, even at relatively low concentrations results in the creation of phosgene gas. It's mostly applicable to older chlorofluorocarbon and hydrochlorofluorocarbon (CFC / HCFC) refrigerants, like R11, R12, and R22...

Thank you for that study!

Hey, Does anyone here have experience burning waste oil in 802/3s? I'm looking to make about 150 gallons disappear, and just wondering if anyone had a negative outcome? I'm mostly worried about clogging the injector nozzles. I'm aware that burning waste oil isn't exactly ideal, but older...

Yes, red arrow is the sender unit. MT5 is the sender, and M5 is the gauge. Full tank should read 29.7 to 36.3 ohms, and empty tank should read 216 to 264 ohms. Your 50something ohms *should* be reading a basically full tank. Here's the test procedure for the fuel gauge. You use the voltage...

I've been swapping out relays for cheapo Chinese ones from Amazon. They seem to work just fine and are an exact match for the plug. Just make sure that you order the proper coil voltage, and that the blade configuration is correct for the plug. Also verify orientation of NC / C / NO contacts...

Thanks Ross! There's so many people here generous with their time and knowledge-- I'm always willing to pay it forward. For the record, I'm ashamed of my generation.

Ross brought the generator over my house today, and we managed to get it running just fine! Injector pump rail was jammed, and one or more injectors weren't lined up. Took a lot of patience. The second after we called it for the night and he drove away, I finished bleeding for the 4th time and...

You only need to remove the rear lower back panel going around the fuel filler / aux fuel connection nook. All of the 5/16" machine screws around the left, top, and right and filler have captured nuts-- nothing should spin. The bottom fasteners are 3/8" with nuts, lock rings, and washers. Those...

On your fuel gauge problem, you'll want to take the rear lower panel off and just take that float / sender module right out. From there, theres just a resistor strip and two contacts. The entire module comes apart, just clean it up nice and good, and it should work just fine again. You'll also...

The aux pump (and low fuel shutdown) is controlled by a dual float switch in the tank-- nothing to do with the fuel level sender. When the tank reaches basically empty, the lower float tells the aux pump to start pumping, and continues filling the tank until the upper float switch shuts it down...

I'm in agreement with PB, worth a look at those rings since you're already this far. Also going to add, are you sure that head gasket wasn't rusted out and leaking? That soot on the underside of the air intake makes it look like you were shooting combustion gas at it, right past the gasket...

Whelp, it's getting there! Today, I received another 20kWH of battery modules (4) and have installed three of them. Total available power when the last one goes on my rack will be 600AH / 30kWH. Right now I'm sitting at 500 / 25 hooked up. In another random posting I *mostly* finalized the...

If you have a faded e-stop button, especially on an 831A from UV damage / sun exposure, you can make it bright red again with a small butane torch. Keep a bit of distance so that you don't char it, and it will turn bright red again! Got the idea from a YT video where they were blasting plastic...

Very cool! Glad this whole thing worked out.

Solar panel mounted to pad via channel strut, and wire protected with 1/2" EMT conduit. IP65 junction box at panel splice. Disregard oil stain on platform. Oil weeping out of the drain plug. Had to open valve with cover on to get tank bulkhead fitting tightened.

NATO plug removed, and replaced with weatherproof SAE jack for solar panel. I used a 4" electrical box blank cover with a 1/2" center KO for mounting the bulkhead plug, and self-taps through the original plug mounting holes in the case. Charge controller riveted to lip in engine compartment...

I generally only change head gaskets, and reuse others that are not torn. I've had very good luck with the Ebay ones.

You can probably Shit, I see used HHO tanks up for sale ALL the time-- some relatively small ones too. A little fitting change on the valve, and it will pair right up to an aux fuel hose. What I dont know is if the head pressure will push fuel through the aux pump without it running-- though...

I had a little time today to play around. My goals were to finish rodent proofing, and install battery straps to keep them from bouncing around since I'm not using giant Optimas (and also have no trays). In the process of installing the straps, I realized that I could get both batteries...
