In case of a Pertronix 2 failure, I want to keep points or a cheaper Hot Spark in the glove box for a backup. I already have a 3-ohm 100-watt resistor. I should put the 3 ohm resistor between the switched power and the positive terminal on the 0.6-ohm coil, which should make 3.6 ohms of combined resistance and be safe for points. Bypass the resistor and use the key-switched power directly to the points and condenser/hot spark trigger. I already have these items and don't want to buy a second Pertronix 2 trigger.
Sound feasible? Thanks. |

Most Pertronix units require a specific resistance so as not to short out the unit prematurely. I know the Bosch Blue coil I have has the right amount of resistance to operate properly. A friend of mine went through multiple Pertronix units because he did not have the correct resistance for the unit.

(IMG:style_emoticons/default/agree.gif) If you read the Pertronix directions they specify a minimum coil resistance. |
