Rover has been switched over to neg earth: I also put an alternator on it and switched the required wires. Do I need to change the ignition switch from the pos earth switch to a neg switch?? I imagine I would also have to add additional light switch. Is it necessary to change out the switch

 

did it energize when you turn on the key? you must have it running by now. did you change the coil polarity. interesting, where has she been all these years that it is just being changed over.
