Heater staying on ???

[Travism]

Hey guys,

I have a 2012 z3 and am on a 2 week holiday. Since Friday we have put 14 hours on with no issue.

Today as soon as I turn the battery's on with the red disconnect switch the heater turns on and will not turn off even when you turn it on and then off with the tige touch.

I have tried resetting the battery disconnect with no luck.

Any ideas ?

Thanks as always,

Travis.

We had one do that and it turned out to be the main power box , relay inside failed, you can open the box and pull the fuse till you get it to the dealer.

Dom what are you calling the main power box? Under the helm I have the tall black panel with 15 or so fuses, a blue box and a black box with a 40A breaker and manual switches for ballast drain, bilge, etc. is it one of those?
