No Electrics

[vorlon99]

my wifes 05 c3 broke down bizzarely tonight.

she came home and parked up as normal, got out of the car and tried to lock it which didn't work.she tried then to start the car again but there are no electrics whatsoever. no display,lights, nothing.she says there was a loud bleep when she parked but otherwise no warning of anything amiss.

I tried to jump start it but nothing, her battery reads 13v. I tried something I saw on various forums about disconnecting the battery for 1/2 hr but no help there either.

first thing I thought was a fuse but none of the ones listed in the book seem to be the one, I assume its one a dealer would have access to?

Welcome to the forum.

 

It could be a maxi fuse that has blown. These are located in the engine fuse box below the top layer - I am not sure how to lift off the top layer without seeing the car but once off you should see 8 maxi fuses ranging from 20 to 80 amps with fuses 4 and 5 listed as being for the bsi. We had something similar to this on a Xsara Picasso where suddenly the car went dead electrically and that was a maxi fuse that had failed. It was replaced and never happened again so may have been a weak fuse.

 

If you do a search on C3 maxi fuses you will find some picures of the fuse box showing the maxi fuses.
