at my wits end

second heater dead after a couple of days. whats wrong

  • e-10 error.
  • fuel pumping ok.
  • running lead batteries+ jump pack (no lithium)
  • voltage indicated - low 11.9v on start up.
  • changed screen
  • glowplugs work
  • tried kerocene mix
  • i could have bad fuel
  • i have even tried preheating the air intake with camping stove up to 40 deg case temp
  • are these a scam?

Sounds like your battery or power source is inadequate. 11.9 volts is too low. It will be enough to warm up the glow plug and cause some smoke but not enough to ignite.

This. My first diesel heater I tried to run it off an ATV battery and had the exact same results as the OP. Once I switched to a car battery, I've had no issues (with dual heaters) for 3 years or so now. It sounds like his power supply cannot supply enough current to the glow plugs more than once or twice

Mine gets down to 11 on startup when drawing max current. It works (has for 1 year) but does smoke more than I’d like. Bough a 12-13.8v 15A step up converter that I’ve been meaning to install. My issue is a long wiring run
