6.2 Tachometer

Post by George Stojkos » Wed Nov 15, 2006 7:42 pm

On the My Humvee Website ( item # 10403 )is a tachometer for 6.2
Anyone fitted this unit. Seems to be a lot of cabling for a tachometer.
Where is it designed to be fitted on dash? Is this unit used on any Mil. trucks ?

Hi George,

The tach mounts to the doghouse on the LHS.
(opposite side to where we Aussies sit :D )
It is designed for the ambulance and shelter carrier configuration which do extended idling periods and has an over temp shut down feature.
There is a 6.5 variant to which mounts up above the winshield in the centre.
But it too is designed to face the LHS.

I've got some pics of the install of both tachs....somewhere :roll:

Cheers

Interesting. I've seen that kind of tach kit before, but I didn't know it was intended for that use. Is there a provision to engage a governed speed for running heavy electrical loads (like a commo shelter), or do you just pull out the hand throttle and run the engine open-loop? What's the big toggle switch for? Does the tach get its input from the RPM sender that's normally just connected to the STE/ICE-R plug?

Since I've configured my truck as a shelter carrier, I'd consider putting in a 100A or 200A alternator sometime. I've wondered about kludging in some sort of governed fast idle mode for running a heavy electrical load.
