What an astoni****ng design. Well, err, forget most of the rest of
what I said. I had assumed that these things were actually controlled
somehow rather than just waiting for the short and then flipping.
I did a bit of websearching and it suggests that they're adjustable.
That is, the current at which they flip is adjustable. Have you tried
increasing it ? This will (as the sites I saw agreed) increase the
energy in of the sparks and thus the damage to the wheels each time
they operate but such damage is inevitable with the design.
