Rob Posted July 25, 2012 Share Posted July 25, 2012 thanks ,have already done that?? might just have to rewire???!!!!Ensure your bulb sockets do not have water or corrosion in them, along with wiring terminations. A high resistance connection will fool a mechancal type flasher into not working properly. These are a bi-metal construction and rely upon a give resistance value to "make, and break" the circuit to cause the lamp to flash. With your voltage varying as it does I would be looking at the charging system for evaluation also. The alternator should be outputting near 14.5VDC at engine idle speed if in good shape.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
