I am having trouble getting enough electricity to my Eberspacher D2 airtronic diesel heater to fire it up. I'm thinking it's the way the thing is wired that's causing the trouble as I've just installed a new LB and still problems.
The heater is an add-on by a previous owner and it was wired straight to the back of the ZIG CF8 unit into the engine battery output connector. This explains why the previous owner told me the heater only worked with the engine running - i.e. as alternator was charging the battery so good voltage. I've tried connecting to the back of the LB connector on the Zig but not enough power to start it. I've set up a 44ah battery as close to the heater unit as I can and connected it up with a short length of wire and it starts and runs fine for hours so I'm guessing there is a power loss/drop over the 5 metre run from LB to Zig and the Zig takes some juice as well.
Am I right in thinking the best thing to do is get some decent 2.5mm cable and run direct from LB to heater to get most power to heater? (I'll stick an in-line fuse in too).
