Lj71 tachometer on hzj75

[JoseR]

I buy a instrument meter frow lj71. But the tachometer and oil gauge don't works. The injection pump have revolution sensor (take from hzj80).

Someone know what I need to do?

The oil gauge should work, they are the same AFAIK.
I think it will be easier to buy a 1HZ tachometer.

After test the meter, the oil pointer fall below off position.
I have not found any meter.

@JoseR , I am going to Panama at the end of the month.
IF you can find one in the USA (ebay or @joekatana), I can hand carry it for you.
PM me if you find one and I will send you my address.

 

[joekatana]

I have more 12V gauge clusters in stock and can ship them to Panama if he has a forwarding address.

@joekatana, did you have any of those lower dash panels in grey?

 

[JoseR]

Some one know how I can test the ignition pump RPM sensor?

Does the needle(pointer) sit really low down when its turned off?
If it does it usually means it is no good. They are very sensitive, if it happened after a test ,maybe you damaged something?

Yes, after doing the test, the needle fell.
The gauge cluster (oem) only turn a red light when the pressure is low. I don't know if use different signal on the needle gauge.
I can not find the electric manual of a bj70 to verify how it works

When they are good they look like this. If you have shorted the wires, they die very quickly.
Do you have an LJ71 or BJ70?

1HZ tach sensor. Its complicated
FZJ80 to HZJ80 conversion Tach wiring problem.

exactly that gauge cluster model
HZJ75 LPMR 92/ ignition bump HZJ80 92/ gauge cluster FJ70 90 /alternator OEM

Damm... It will be an electrical problem or wrong pressure sensor????

The oil pressure sensors are all the same for diesel , petrol, car, landcruiser, bus etc. They all look like this.
