I don't know diesel... but mine is powered off the coil on my 2F.
Do you have anything like a coil.

I have a 2H bellhousing that has the sensor that got smashed by the wrecking yard I got it from. But I believe that sensor records everytime a magnet on the flywheel passes it. Is there anyway to inspect to see if magnet is there? Other then that I have nothing.
As Litp said there's a flywheel sensor on he bellhousing. Check that and the associated wiring to The tach

I took the sensor out of the bell housing looks fine I guess I need to check it with a multimeter but not sure how to do that
@lostmarbles is not on here much any more... He lost his BJ40... Let me contact him through personal email and see if he can offer any insight.
I'll get back to you, if Tom doesn't respond to this thread.
Could Joe Katana be any assistance?

Hi Danny, Hellgate and everyone..
We''ve just got back from a little steam excursion and I'm still running around chasing my tail trying to catch up on things...
Oh.. And on this trip (the day before yesterday) I spotted the latest acquisition by the New Zealand Army - Flash eh? (Just to show that I haven't lost interest in the 4x4 scene.)
But here's some tachometer information I've quickly found (of the stuff that's still have available to me here).
This appeared in Toyota literature in 1980 to show off the "new technology" that was then being included in the new 60-series (and that would be similarly applied to the outgoing 40-series and the HJ47 model):
Is this of any help?
Cheers - Tom
