I tore the fuel valve completely apart, cleaned everything, reassembled, and calibrated it. It's supposed to output 14 ml/min in low/start mode, and 28 ml/min in high. I set the low to 15 ml/min, but my high is only 20 ml/min. I figure the start mode is more important to have to spec, since...

I think they're still calibrated for selling to the Military.

Update: I went to calibrate the valve. The good news is I get fuel coming through the valve now. The bad news is the valve also leaks fuel in several places. Since the valve sits above the igniter, I don't think I want a leaky valve dripping fuel down the side of the heater, into a puddle...

Thanks guys. I had fuel out the bleeder and power where it was supposed to be before I tore this apart. I've learned a lot in the process, mostly from SS. Bjorn's been a big help, and his article answered a *lot* of questions.

I took the valve body apart. The cork washers behind the coils gave me pause, but the rest of the disassembly was straightforward. I was afraid I'd destroy the cork washers in removing them, but with patience and some dental tools I got them loose and out with no damage. First photo shows the...

That's likely. I'm trying to trace through the wiring to figure this out. Is there a way to manually work the valve, and see if it moves freely? I'd love to see documentation about how to effectively troubleshoot these.

The fan blows air, I get fuel out the bleeder, but no heat. I pulled the glow plug, a coil which looks like an old-school car cigarette lighter on the end of a long spring. I closed the fuel valve, turned on the heater, and the coil immediately glowed hot. I get no diesel smell, so it seems...

The M1010 box heater is PN 10530B. I found the TM for the 10560G, TM 9-2540-205-24&p. I worked through the troubleshooting section to the point where I'm supposed to remove the igniter. But my 10530B doesn't match the TM's 10560G pictures, so I'm hoping someone can point me to the right TM...
