Hi my name is Caspar and I'm a moron.

Today I fried just about every fuse in my new Hanse due to immense stupidity.

I had charged the house battery while it was disconnected and decided to switch the +/- cables when I reconnected.

A flash, a bang, wife screams, kid screams, I scream, smoke and smell of melted metal.


Now to be a bit more serious:
So far I have uncovered the following damage:

Electrical panel is dead. Found one 30 amp broken fuse on the rear. Suspect this might be the fuse for the panel itself?
VHF and stereo is dead. Confirmed just broken fuses.
Charger relay fuse exploded, 125 amp.
Charger cable to start battery deformed. Needs replacement 125 amps.
Probably more fuses, but since I don't have replacements at hand I have to wait until monday to get replacements.

If all the damage is broken fuses I will be very happy.

Could this possibly have done damage to the battery itself? The negative terminal got "weld"-damage to it, but the duration was very short (luckily)

And an update Confused

Replaced 125amp and 30 amp main fuses. No light in the electric panel

On closer inspection I see several mini blade fuses have gone pop. 10 and 5 amp fuses to known and completely mysterious devices.  I thought the 30amp fuse on the rear of the panel would bring it back to life but alas Unhappy

To be continued.

Why did you decide to switch the cables? I seems to have caused a bit of trouble for you, to say the least.

Sorry, I meant to say swapped. I had disconnected the battery in order to charge it with an external charger before winter layup. The mixup happened when it was time to leave for home and was getting dark. I should have double-checked the polarity, but I didn't...

Bad news: After changing all broken fuses (15+) the panel is still dead.

Good news: I now know my electrical panel intimately...

I might have to order a new one. 800 euro...
