Technical Problems with electrics

[Topa]

I used the search, but I didn't find answers.

Okay, the problems started after I changed the battery. I was a little bit careless and I didn't connect the minusconnection proberly. So the connection was like on/off (sparks).
After that I found out that electric windows, central locking, additional heater (Webasto) and seat heater doesn't work. Any ideas, what broke down? All the fuses are ok (checked twice).

I used the multimeter and so far I found out that there is now voltage getting to the webasto timer.

Van is a 2002 (newer model) with 2 litres JTD (HDI) engine.

EDIT: Yearmodel

If this happened to me I would be looking at the various connecting blocks & tags near the positive terminal.

You would have got a bit of sparking as you connected the earth lead to the battery as there is always something live (radio or alarm) even with all accessories switched off.

However the positive terminal is tucked well under the scuttle and it is more than likely that the associated cabling got strained when you changed the battery. I believe there are some main fuse links around there to protect the cabling leading to the accessory fuses.

Good luck, not the best of weather to be tinkering outside.

Ok, thanks. I will check the connections near positive terminal.

And you are right, the weather isn't the best possible...

Problem solved!

One cable was snapped. Cable is the one between positive terminal (from 80A fuse) to passenger side fuse box. Quite thick cable.

The cable was hidden when I checked the connections until I removed the battery.

Thanks crossigkeeper for a good advice!
