Aftermarket Tachometer
 

I just purchased an Autometer 2888 diesel tach, but it says to put the probe on the laminations of the alternator. my truck has nothing such of the sort.

I seen some aftermarket tachs on 12-valves, and was wondering how they got em to work...

for some reason i want a different tach then what came factory...

Bout the only thing you can try is move the probe in different spots on the alternator.

where does the stock one get its reading from...the crank, cam or alternator:humm:

Believe it's alternator. If it read off the cam, might give to high a reading?? :D

its off the damper.
