Does anyone here know anything about the inner workings of the tacho that Rotax supply for the 912 please? Part no 966403, specifically for the 912.
I have one that overreads by a factor of exactly 2 and I'm wondering if there's any chance of fixing it. The trigger pulse from the coil is double as the magnet passes it, a + spike then a - spike, I'm wondering if maybe a failed diode might be causing it count both spikes?
Not easy to open up but nothing to lose!
