[gilge85k98]

Hi there.
I have a gu 3 ltr diesel whitch i have converted from a 3 ltr turbo diesel to a 4,2 ltr, diesel.
I have wire connection problems as follows: the wiring for the speedo and the revcounter jump
up in the armature without the engine running or the car is driving.The reserve tank dial jumps to full whitout a drop in the tank,the airbag light stays on and don't go off.
Has anybody made a conversion like this and can advise me i would verry mutch apreciate it.
A drawing would be of great help if possible.

Gday mate most would jump over and introduce themselves first, but sure someone will be along
soon to help you. have you searched the archives ??

You need to give us a bit more information regarding the conversion, was the instrument cluster replaced? or did you fit a module to modify the tacho signal. What transmission are you now running.

The first things I would check are all the fuses and earths. Make sure you have an earth lead going from the negative battery post to the inner guard/body and one also going from the body to the chassis.

Hi there
Thank you for your reply i will try to reply by describing so good as possible my problem whit the
electrics as i been having. I'am not an electrichen so excuse me if it is not perfect.
The engine is a 4,2 ltr diesel mounted into a GU 3LTR diesel, keeping the 3 ltr harness.
THE PROBLEM;
1) The cluster as far as i know is the right cluster (3 pinn plugs )
2) The problem here is if i swich to ignition the rev counter, the speedometer the light for the airbag
gets on and stays on, the spare tank shows full but the spare tank is empty.
3) The sender for the speedo connection i have hooket up in the only socket for it where it will fitt in
but the speedometer when i drive 70ks will show 120 +
The revcounter will show 4 to 5000 ks wich should show 1200 revs.
The light for the air bag stays on permanently.
4) I had the cluster send to somebody to quensland but it came back whit a modem but that would
not work. i then send the cluster to south australia that did not work either.
5) All other functions on the patrol work fine.
Since the 3 ltr diesel has the same type of sender as the 3 ltr the the revcounter should be working,but it acts
in unison whit the revcounter.
I had also an elctronic enginer w0rking on it but no result there either.To tell you the truth
i getting a bit confused and thats why i hope somebody has made some experiens in this
aerea.

Good Day treedogs


I have a big service manual (360.00)but i must say one must be a japanese to make some sens out of that balony they have printed and i know how to read drawings.
What archives do you mean? I have tryed nissan myself but they don't seam to fallover to be of great help so i have given up trying there.
I would apreciate if you let me know what archives you have in mind.

Cheers Gilge

Hi Yendor
I did look after the eart connections but there seams to be no probblems they have some corrosions but nothing serious i could find there.I am still using the same cluster from the 3 ltr.
What bothers me is the fact that speedo, revcounther, spare tank lights, airbag lights come on as soon as i switch on the ignishen that is the problem and i have had the feeling that there is a short in the wiring but as far as i can sheck i can not see a problem, i have not bared the wiring wrap on the cabel loom. All other funktions work fine on the patrol. I have also changed the computer but no difference at all on the problem on the cluster.
The sender for the speedo and the revcounter on both engines work on the same princiep but the cabel for the revcounter on the 3 ltr motor is somwhere in the harnes and i can not find the revcounter cabels whitch lead to the cluster because i have to find these to connect to the sender of the
4,2 ltr engine. The connection
from the speedo sender seams to fitt on the harness plug because the plug fitts only in the correct
socked
I would appreciate any help on the matter.

What model was the 4.2 out of? are you still using the 3L gearbox?.

How was the engine wired up? are you still using the 3L engine wire harness?

The tacho will need to be re-calibrated going from a 4cyl to a 6cyl or is this what they did when you sent the cluster out?

I'm not sure why your speedo would be reading out, maybe it's been damaged?

Have you checked that the alternator is charging, does the battery warning light in the dash come on when the ignition is turned on and go out when the engine is started? This could be the cause of the problem with your sub tank light, gauge and airbag light staying on (unless you have also replaced the dash harness.

I would also run an earth cable from the negative of the battery and connect it to the chassis, disconnect the battery for an hour and see if this solves the warning lights staying on.

Killa Kustom Kables modifies the 3L engine wire harness to fit the 4.2L engine that includes the module for the tacho re-calibration, all you have to do is plug it in.

This option might be easier and cheaper for you in the long run.

Hello Rodney
I'm sorry that I have not answered your e-mail sooner but I have not been near my computer for ages.
I have also tried to get the car going but so far no luck.The problem is still the same. It seams that some body had a go at the loom and has cut some lines on the loom and at the same time reconnected them somewhere else, and by doing so the whole setup is hay is bugs.Perhaps you have some idea in or near Sydney which I can call for help?
The think that stumps me, how did that car ever run?
If you have any idea please let me know.

Cheers gilge

Hi Gilge,

Sorry mate, I don't know of anyone down your way that could help.

Hopefully one of the local guys can recommend someone.

Cheers Rodney

The first step of things I might check are all the circuits and earths. Verify you have an earth lead going from the negative electric storage device post to the inward guard/body and one additionally heading off from the form to the frame.

As I said i changed the engine from 3ltr to 4,2 ltr diesel but i kept the 3ltr loom.The problem i have is the
cluster witch i had to change because the cluster was damaged and did not work. I found that a person had worked on the loom and had cut cabels and had rerouting made witch the computer will not accept .Theand result is that the cluster instruments act crazy,both the speedo and tacho
jump to up 35 km and 800 revs, the spare tank and the main tank show full the glow light is on and
does not go out.
I have checked the fuses they are ok
I can start the engine the low plugs cease operating as soon as i switch back to start. I am not an
not an electriker but it i have the feeling that i have a short in the loom but i have run out of idea
If some body has an idea how i can correct this problem i will appreciate it very much .
Cheers Gilge
