I tried the "butt method" but it did not work very long. Others have had better luck. I took mine out and completely resoldered it. It is potted so it's a bit of a chore to do.

It's been working for 2 or 3 months now.

PS there is a pickup down by the balancer. I believe it generates a small signal from the magnetic effect and feeds to the cylinder shaped item described earlier. I don't have a schematic and didn't put a scope on it so I don't know what signal levels we are talking about. I've been told that the sensor almost never fails... it's usually a bad solder connection in the cylinder.
