Boyer contact breakers

I've opened the cover of the contact breakers and the wires are melted.

Why?

Could that happen because of an incorrect timing?

Thanks!

Sounds like electrical current was applied, in amperage sufficient to melt the wires. A DEFINITATE NO-NO for the micro-electronic trigger circuit.

The only other thing that can melt wires is heat; that much heat in the timing chest would be disastrous to the engine.

Either way, you've got "issues".

I'm confused.

Do you have a boyer with points?

If you have a Boyer pick-up and connected the two wires directly to your battery you wouldn't draw enough current to melt the wires.

No, Arch :lol: .
I have a regular Boyer ignition, but my English is not as good as to explain everything as clear as I'd like...
:wink:

The point is that the plastic on the "rotor" wires have melted, while the wires that come from the coils are like new... :?

Sparkplug, I think that your engine suffered a general 'meltdown' in the sense of catastrophic failure. It is difficult to know what happened first but it could be as simple as a chafed wire in the timing cover although than I would have expected a misfire first. There should be a small rubber grommet there.

I think that you can rest assured that this sort of failure is most uncommon with a Boyer and almost certainly caused by external factors.

Timing in itself couldn't make the Boyer pickup overheat and even engines that have seized due to lack of oil don't get hot enough to melt the wiring.

Maybe your poor old engine was shooting flames out underneath ? :shock:
