Default Re: Automated shift lite tach problems

Chip
Is the tach working right all the time? Any bounce to it?
Check ground on all of it. Also wire from box or tach and the 12 volt source.
Sounds like a loose wire IF the tach is working right.
Also, not sure if it's LED or bulb type light but if bulb, make sure it is not loose.
I will call you later.
