In search of 1st gen Diesel tachometer

Postby 1988trooper2auto » Tue Jan 10, 2017 4:58 pm

I'd really like to keep the original trooper tachometer if I can when I swap a diesel into my trooper.

If you have one let me know. Thanks

On the 4jb1 the sending unit is in the injector pump. Is that the same area on the diesel 86?

If so it would just be wiring I believe.

EDIT FOR CLARIFICATION: The tachometer in a gas-engine Trooper is different from the tach in a diesel-engine Trooper.

Jerry told me the sensors are different, and therefore, the tachometers are different as well, due to the type of signal sent.

I know for certain the connectors are different, with the diesel tach being a slightly larger connector, so the wiring is not just a simple "plug-n-play," unfortunately.

I don't have the connections worked out yet, but that will happen in the next week or two, as I've got to get it done, so the owner can come pick it up.

I'm not sure, I just pulled the tach from a diesel at the yard as i was told that might be a hard to find part without realizing the sending unit was also needed. If you want to pay shipping, I would just send you the tach as i have no use for it personally.

thanks, Kevin

EDIT: I didn't realize this was someone else's request for a tach. Didn't mean to undercut or preempt that. Sorry. PM retracted.

ok well im looking forward to what you come up with. my 4jb1 is incoming today(leavingshippin)
and plan to start soon there after.

i will make a thread for it when it get here.

so any help is appreciated.

so do you think other than the connector does it seem much more difficult. or what are people using for there swaps? i know there isnt many.

would a diesel tach be more useful or research my gas tach to work?

Mileage on a tachometer won't matter, as long as it's working.

Okay, update on the diesel tach situation:

The tachometer is slightly different, due to a different type of pickup sensor on the fuel pump. If your fuel pump is equipped with the sensor (some aren't), you'll see two wires coming from the fuel pump tach sensing circuit - one is black and the other is black with red stripe (same colors as the gas engine tach signal, located over near the battery - two wire connection which stands alone). The black simply goes to a ground connection and the black with red stripe is the signal to send to the tach. I ran a wire from the fuel pump over to the connection near the battery, which was already wired into the instrument cluster, and made the dash connections easier.

Google "Isuzu pup tachometer conversion". I think it's the first link: http://www.isuzupup.com/viewtopic.php?t=12049 This thread deals with the C223 diesel, specifically, but I believe it's the same circuit modification for the 4JG2.
