What will trevor do next to me?

[clasabro]

Trying to get the old beast back on the road for spring. Turned on the ignition switch and the rev counter shot of scale and stayed there as long as the ignition is switched on. Any ideas?

Have you got the white / black wire on the - neg side of the coil? Sounds like you are putting +12v to the pulse side of the rev counter...

All wires are correct. Rev counter was OK one minute and not the next
