I hate wiring just spent a lot of hours rewiring the rear lights I notice a crap job done before and battery died in the process I stuck it on charge and left it to return to another trying to move it and tried starting it.now the batt was very dead still ,it wouldnt start but I did notice the fuse blown in the charger. I replaced it but didn't have time to check if it screwed the wiring in the car or blew any fuses though I am thinking with the luck I am having it has done something.as I did notice tail lights not working,though I thought it maybe just cause the battery is really low. So can anyone shed any light on this will trying to start it with a charger on it blow the ecu,fuses,relays etc
