EBERSPACHER MAIN FUSE - LOCATION?

[alisdair4]

Tried to turn on the Eberspacher this morning. The timer unit indicated that the heater was on, but no noise or heat. I suspected the main fuse (25A according to the manual). Can anyone suggest where the main fuse is? I only have a circuit diagram showing that it exists, not where it is!

Certainly on my D4 its in the main wiring loom near the battery connections. Check for poor connection of the fuse & holder-this does occur sometimes.

Despite the eberspacher being fitted by professionals, the main fuse on our boat was under the floorboards in the cockpit locker.

My advice would be to follow the cabling from the unit back to the batteries.

The main fuse is an in line fuse in the +ve power lead.

The original fuse holder can be prone to making a poor contact.

I have replaced quite a few of those holders with a single car blade type in line one

You could try a jury rig to check if it is the fuse or wire or connection. Of course you need to locate the fuse for future reference.

jury rig on the main fuse for this line is not a great idea due to the large current that can be drawn during start-up.

By jury rig I mean a lead of the appropiate section and with a fuse. Jury rig does not imply unsuitable .

On my D3LC, both fuses (car type blades 25 & 5(?) amps) are mounted adjacent to battery take off point at the battery, not wired via main battery switches so programmer works with other circuits disabled. Suggest you look around the battery area.

Thanks for all the help. I have now found the main fuse, and it is intact! So back to the drawing board -why else wouldn't the damn thing work?

Oh [--word removed--]! If our experience is anything to go by you can be in for a treasure hunt. There was a thermal breaker hidden amongst the wiring in the electrical panel and another fuse actually in the E unit
Good luck!

There are two fuses indeed , one main fuse and one for the fuelpump .

 

[pcatterall]

Never seen one for thethe fuel pump!! main fuse 25amp and smaller fuse protecting timers is usuall.

Which model is it? Just wondering if it's one that can lockout (like the D1LC)

 

[alisdair4]

I think it is a DILC (ie, bottom end of range) - but all the paperwork is on the boat. How can I lock myself out?

Check the forum for lockout and Eberspacher. Certain models had a kind of "3 strikes and you're out" functionality. After a certain number of unsuccessful start attempts the unit believes there is a serious problem and locks you out until it can be reset by an engineer.
