Chased that one thread that needed it and re-installed the intake and the wiring: After completing the wiring, I flipped S1 to pre-heat while having a voltmeter on the tip of #4 pre-heater. It started out at ~25.5V and over the following 10 seconds, slowly dropped to about 23.5V. I then...

Yep, 12V heaters. 2 in series on a 802, 2 pairs of 2 in series on a 803. 12V is stamped on the side of the housing. So 288 Watts per heater for a total of 576 Watts on a 802, and 1,152 Watts on a 803. The 0.5 Ohm I'm getting is on each heater not connected to anything else, manifold on my...

The preheaters are 12V each and wired in series. 12V across 0.5 Ohm is 24A and 288 watts. That sounds reasonable. If they are supposed to be 5 Ohms, that would only produce about 29 watts per preheater @ 2.4A, which seems on the low side. The gauge of the preheater wires coming from K18...

I rechecked the resistance and I guess I just wasn't patient enough last night. After waiting 5 seconds or so, the readings on all 4 preheaters settled to 0.5 Ohms, so the same you are seeing @loosegravel I need to chase the shaft on one of the preheaters: The other 3 are fine...

I’m 99% sure it was S1 since it won’t spring back to OFF after using pre-heat. So when shutting down the unit, one can easily turn it past OFF and it will be stuck in pre-heat. That said, I’ll be sure to check K18 before putting it all back together again.

Finally had a chance to pop the roof and have a closer look at the intake manifold. After removing the muffler, this is what I was greeted with: #1 and #2 took the brunt of it. Closeup of #2: I was able to unscrew #1 and #4 nuts pretty easily, but #2 and #3 required that I hold the...

I just checked S1 again, and what do you know, it will get stuck in Pre-Heat is not careful. It also feels real mushy. See below: So when I shut it down yesterday, it more than likely got stuck on the Pre-Heat position. So I'll start by swapping it out with the S1 from my spare set, which...

Thanks for the suggestions. I'll be sure to pull the intake to make sure none of the heaters dropped any fragments. Good to know pre-heat always come on during cranking, that would explain how K18 closed in the first place. I guess that means the heaters stayed on while the set was running...

I picked up a 803 a few months ago in good condition with a little over 5,500 hours on it. Runs good and I load tested it last weekend and it held a 12 kW load without breaking a sweat. Fired it back up yesterday and ran it for a few minutes and then shut it down again. Temps were in the 40's...
