I had a bad one and replaced it. Now when I pull the switch it wont activate.
Are you saying it has not worked since replacing the clutch? If thats the case, you may have a bad clutch coil OR the air gap in the clutch is set too wide...
The most common problems,
the switch can fail, usually becoming intermittent...
The clutch is not getting a good ground...
the fuse is either bad or corroded...
wire from the switch to the clutch is compromised...
