Battery connected to wrong terminals

[mikebee]

I connected my battery to the wrong terminals on my slk 230 after the light bulb died in my garage ,yes a very stupid thing to do! The starter motor won't turn over and I am really worried about what sort of damage has occurred.
Can anyone out there put me out of my misery and offer any suggestions, my car is a 2001 model.

Because we all make the occassional silly mistake, most manufactures design in measures to protect the car from us! so hopefully it won't be too serious.
When you try and start the car the ecu checks a number of things first such as the cars in park, key fob security, etc You'll really need to get the looked at by somebody who can read the codes to see what the ecu thinks is wrong and hence stopping the car from turning over.
Tracing what's got power and whats not, may be a start?
So far I've been really impressed with the Mrs SLK, apart from the rusty wheel arches!
Good luck
My local Merc garage have been amazing good! And even more surprizingly, really good on price, get a quote first though!

With a bit of luck you will only have blown some fuses. have a look at this thread assuming you have a R170? K40 relay circuit and associated - Benzworld.org - Mercedes-Benz Discussion Forum
