Installed 2nd hand Eberspacher - it keeps blowing main fuse!
Posted: 16 Feb 2007, 10:23
I've had a good search on here & have spent mainy hours chasing the wiring with a multimeter looking for faults & shorts, but still no joy.
I was sold the Eber as a working unit but have yet to prove it. The wiring to the thermostat on it was very dodgy with lots of block connectors, miscellaneous wire & insulation tape, so have VERY carefully removed all the crap wire & soldered/heatshrunk all the dodgy connections. I have checked & rechecked the 3 wires & am 99.9% certain they are correct (checked against schematic).
When I switch it on at the thermostat on/off switch the fuel pump sometimes clicks once or twice & then the 15A inline fuse from the battery blows. I have checked that the fuel pump works by putting 12v direct to it (it needs a pulsed current to work doesn't it?!) & it seems to be okay. I don't want to keep trying it in case it damages anything else!
How do you prime these pumps as I can't suck fuel through it?
I have now run out of ideas. Are there any Eber experts in the Warwickshire/Midlands area I can visit? Is there anything I should be checking?
Please help, surfing & coming back to a cold van isn't much fun!
