Trident Eberspacher Heater Fuse

If you don't get any immediate responses, you may get more info if you say what make/model of power control system you have, as the fuse locations tend to depend on that as much as anything else.

Having said that, typically an Eber is powered separately from the habitation electrics so that it can be used at any time - certainly ours (in a 2005 Trooper) can be used while the van is being driven.

I've owned several vans with either an Eber or a Webasto and I've never had one blow a fuse. They can, however, "lock out" if the diesel in the main tank is allowed to get really low. If that happens, they will typically have a small number of retries and then will stop retrying.

I can't offhand recall the procedure for resetting them, but there's plenty of info on that available with an internet search, if that becomes necessary.
