Hi Guys, New here. Broke down the other day due to my own stupiditity - rotor arm cam loose and flew off due me bolting the rotor to the distibutor as I didn't have correct screws to screw into the distribtor. The nuts worked loos, the rotor arm broke off and I was stranded. Anyway, got towed home and i replaced rotor arm and fixed properly but find I have absolutely no spark. I do all the usual things - replaced condensor, checked coil with multimeter. I then discover that I have no rear lights working or side lights nor boot/bonnet illuminating lights. As they were working before, could this be related to lack of spark? All relays seem to be working. I'm at a total loss. Any suggestions? Many thanks
