My multipla 2004 (54) has been struggling to start for a while so today i changed the battery. Dont ask me how but somehow i crossed terminals for about 5 seconds and a bit of smoke came up from way down below. I did the battery change and all was ok, the car started up 1st time and all the lights, indicators brake lights worked. I had to take my daughter home tonight and i noticed the stereo was not working also the fog light. I went to reverse up my daughters street which is on a little bank and the car cut out and would not start, the abs/ ebd warning come on the dash, also the engine management and airbag light, i bumped started the car to get home. when i got home i switched the engine off and now it will not start at all and the warning messages are on the dash. Is it mechanic or auto electrician time? i checked the fuses for the sterio and it was ok. The battery teminals are still connected ok and the lights alarm and things still work apart from starting. I am not very good where it comes to cars, where would my best course of action start.
Thanks
