I was replacing the ballast on my headlight on a 52 plate Focus ST170 and dropped a spanner on the negative terminal and made quite a spark for about 3 seconds.

Since then the Brake warning light, traction control warning lights, and ABS warning lights have remained on.

I checked every single fuse in the bonnet and glove box and one was blown but was for something unrelated. All others were fine.

I have heard there are many inline fuses coming of the battery, but I dont really know where. Could one of these be the problem?

Or is it likely I have blown or shorted something and need to go to an auto electrician?

Thanks in advance.

 

Why don't you start with having the fault codes read from the ABS?
And then based on the codes investigate further.

 

Great! thanks for your help. I looked it up and will try to buy one of those readers. Cheers!
