Testing inex ingnition system (red)
Would anyone know how to test these systems to see if they are faulty, we have two, one is new the other came with the car, we're not sure if there is a short with the electricals or if these boxes are being blown by a fault in the harness, we get a signal to the boxes ( red led falshes when turned over)....we replaced one with a new one, the engine fired after a few minutes and ran, we switch it off and went to start it an hour later and nothing!!!!..... this is seriously doing my head in .....any ideas?
