A couple weeks ago I drove to the local cruise and part way there (less than 3 miles) it just quit working. Other than the obvious loose or broken wire what else can go wrong? Do these suddenly go bad? Is there any kind of internal fuse? I will track down the power, ground and trigger wire this afternoon. Hope it's just a blown acc fuse or bad connection. If it is a dead tach, is autometer still the go to brand or is there something else you like?

Thanks

In theory, there is no difference between theory and practice. In practice, there is.
