Boyer in a Victor

seattle##gs · Apr 15, 2024

I want to swap a Boyer black box in the Victor to see if the original is good or bad. It seems to fire way out of time. The battery is a lead acid battery and holds a charge of about 12.3 volts. That could be the problem. It could also be the black box. I have a nearly new Norton black box to substitute. Would this work? On the original box it requires connecting both wires to make it work. Anybody done this? A twin box on a single motor?

I thought the single and twin Boyer's were the same?

They certainly look the same. I can get a spark by turning the ignition on and off but it feels like it's badly out of time.

The boxes are the same, however all the boxes vary on timing by about up to 10 degrees due to component tolerances hence why the need to strobe after fitting also applies when changing boxes.
