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. |

Hopefully, it's as easy as this.

QUOTE(SVG223 @ Apr 25 2025, 01:02 AM)  Hopefully, it's as easy as this. I took it for a test drive; the backup system works well. Even with a 3 ohm resistor the new coil works better than the original blue Bosch. After 50 years, it did its job. Now to hook up the Pertronix 2 ignitor and remove the resistor. I will put the resistor in a bag along with the Hot Spark trigger, a Phillips head, and a 7mm wrench, and put it in the glove box. |
