M1010 personnel heater issues

[TechnoWeenie]

Rear heater in M1010 isn't working...

Previous agency (SO) ran a new wire to the pump....and the pump works....I can hear it clunk..


The drain at the rear..when opened..dribbles out at a decent pace....more of a surge than dribbles but hard to explain...

Hold start position. ... fan works....strong diesel smell.... no heat....

Pump seems to work.... I'm thinking ignitor maybe?

Most info I see on TMs is about replacement, not repair or troubleshooting... other than bleeding..but I did that.

Thoughts?

Mine seems to work better when the temp switch is toggled to low, might try that. Also check to see if your indicator bulb is working, won't affect it starting but lets you know when it does.

How long do you have to hold it in the start position?

3 minutes approx, when it starts is sounds like a jet engine turbine winding up and gets louder, it will be obvious when it's full on.
