installing tac

[tourdog]

so i will ask the dum question were would one install a tac on the engine not in cab i have a nice recall tac out of old truck was gas now have m1010 love it want to put it in new

I think to put a tach on a diesel you need a converter box or something to plug into your alternator, to read the revolutions off of that or something. I don't know for sure but I remember reading something like that. Its not as simple as hooking up to a coil wire on a gas engine

jaytee you are correct.

you cant just hook one up to a spot on the engine, you need to get a tachometer that runs off the alternator and have it calibrated.

How would one check the rpms without a tach?

type in
tinytach into your searchbar...they have a small pressure transducer that clips to an injector line.They are pretty cool little unit.

We use a strobe light to check RPM on engines, shafts, etc. where we cannot have or do not have a tachometer. Interesting how it totally freezes the motion to the point we have to watch ourselves because we might absent-mindedly reach into a turning fan, etc.
