There are two electronic modules, on top of the motor, marked A and B, these modules each have two plugs attached to them, one 4 Way and one 6Way The 6Way plug connects, mostly to the Coils (HT Side), but one of the connectors attaches to a red wire, that is from the exciter coil, mounted on the back of the motor, where the pickup sensors are mounted. The 4way connector is for the pickups at the back of the motor. These two red wire comes from the back of the motor, and are shrouded in metal braid, which stops just before they plu into the 6way connector. It is just before the 6way connector, that the wires break inside the insulation. So all I had to do, was find the end of the Red wire(s) that still worked, bypass the 6way connector, and wire it straight into the respective modules.

Where is it located?

(Found the problem using the pin and Ohm Meter method) I then bypassed the plug, with a new piece of wire, left the second ignition unchanged. Flew for 2 Hours, to discover that the second ignition, now had a broken wire! About 15mm from the plug! In both cases the wire had broken INSIDE the plastic insulation! Please note that I did NOT install any of these wires, this is as installed by ROTAX. How can such an expensive engine have such crappy wire!

The engine would quit on one" mag " After a lot of wire switching,etc it ended up being a broken wire. Check the red power wires to the A and B modules. (or whichever doesn't work) The way I did it was to get an ohmmeter and but one lead to a ground on the engine (engine is NOT running by the way) then get a sewing pin and work your way down the wire from the connection at the modules. Punch thru the plastic sheilding of the small red wire with the pin to make sure you have continuity in the wire.Do this about every couple of inches or so all the way to the back of the engine I would be willing to bet you will find a break in the underlying wire and it is just barely touching at the broken end thus causing the module to be intermittently powered.That was the case with mine AND the break was in a straight wire run making it totally invisable from the surface . I found the internal wire break just a few inches from the module connection. I cut the wire,spliced it ,and am now back in business !
