Just been trying to wire in my rear fog lights and all of a sudden the stereo didn't work and now the car won't turn over? I think I tried it first thing this morning and worked fine (starting to doubt myself now). Was checking the lights to see if Heckler's PCB's are wired in correctly and noticed that the black wire attached directly to the ignition, going into the switch wasn't completely connected, so reconnected that and that was when i noticed the problem. The wiring has been like hat for ages, I changed the fog light switch last week but it wasn't wired in until yesterday with the PCB's
Any ideas what to check? Starter motor is turning over but not catching.
