Mystery Wire was created by Tom_england
Hi All,
I'm currently re-wiring my Rotax 462 and I've found this wire attached to one of the ignition coils, but I'm not 100% sure what it does. I thought it might be some kind of earth, but it appears to join one of the lighting cables just before entering the regulator-rectifier. I can't see any reason for it to be there; am I missing something obvious?
Many thanks,
Tom

Looks like a ground to me.

Roger,

Thanks for your quick reply (and apologies for my slow one).

Is it correct for this to be joined to one of the lighting wires then, or should this actually go to ground?

Many thanks,

Tom

A lighting wire does have a ground so yes it could be and this may be a ground for more than one thing. Hard to know from just this picture and not seeing it.

I'm refurbishing an old 503 and that also has this wire. On my engine it goes to the 8 way connector but after that, who knows.
