Ignition Coil: Testing and Inspection

Fig. 50 Testing coil secondary winding.:

1. Ensure that there is 10-30K ohms of resistance between the high tension terminal and either of the primary terminals, Fig. 50..

Fig. 51 Testing coil primary to secondary isolation.:

2. Ensure that the resistance between the primary terminals, Fig. 51. and the case is no less than 10M ohms.
