ill put some better pics up once i put batteries back in and wired up those picks are from a few weeks ago. and im in forrestfield wa. she got a professional tummy tuck, ill put compliance plate picture up to if people would like to see it?
Ok so when you disconnect the positive from the first (LHS looking from the front) battery, you still have the issues. I am assuming you don't have any Aux (third) battery connected up anywhere? Kinda got me stumped as well but going to throw some ideas out there..
The way they are wired up (guessing its the same as my Safari) is :
You draw power from the LHS Positive Battery
A long cable runs from the LHS negative across the front of the car (behind grill from memory) to the Positive of the RHS battery
The RHS Battery negative is then earthed to body etc
How much voltage do you have? Is it leaking 12v or 24v or??..From memory Oil pressure and water temp gauges are 12v (run from a little invertor in the back quarter panel) so may help point in the right direction.
By the look of it though you have something connected to the second battery (RHS) so using it for a 12v Source?
This may explain why you see two different voltages on the batteries. Although I would expect to see the RHS battery lower. If you keep drawing 12v off one battery you will find your battery life is effected and unfortunately with a 24v truck once one goes its a good idea to replace both as the old one will bring the new one down to its level. You can buy battery equalisers, but even they are not perfect.
My first check would be to see if there is any broken insulation on the cable that joins the two batteries (from LHS Neg to RHS Pos) that was shorting out. Even disconnecting the positive from the LHS battery would still leave 12v coming from the RHS battery. So what voltage is leaking? What happens when you pull both the LHS pos and RHS Neg off? Does the problem stay/go away? The fact that when you pull the pos from the first battery and still have stray current got me thinking along these lines. But then again you say you have checked and replaced all of the battery cables so kinda rules this one out..
Pull ANY after market wiring off the batteries leaving only the basic (standard) wiring to run the car.
If the problem goes away, add the extra wiring back one by one and see which one causes the problem.
As 3Dogs said..do things one by one..Its just going to be a matter of taking your time and taking things out of the equation.
"Pull ANY after market wiring off the batteries leaving only the basic (standard) wiring to run the car.

Gotta agree with that.
Also measure voltage on batteries with everything disconnected.
Extremely logical... I told OP to do that back in #5
The only way the chassis can actually be "live" WRT to supply -ve is a high resistance path to Chassis from the Supply.
That could/will be why his 12 Volt instrumentation is playing up, it isn't getting 12 volts WRT to chassis anymore.
On a 24 Volt system the chassis will appear live from the RH battery -ve (it will be 12 volts WRT earth obviously).
But if the OP is connecting a test lamp to LH side -ve and putting the probe on the engine or chassis and the lamp is illuminating then his "earth" isn't an earth IE the earth cable is high resistance.
It could be the engine to chassis earth.
His mention of the globe being brighter at different points screams earthing issue but as we have all mentioned, the only way to go is start at a logical point and go one step at a time.
Best check will be to put the test lamp on the chassis/engine end of the earth cable and go back to battery -ve.
Light on = battery cable faulty
Light off = battery cable OK
If light is off then go to Engine and Chassis and wherever the lamp glows is the broken earth strapping
looks clean enough the patrol that is and looks well looked after {loved]
like all Patrols should be, seems strange its just happened,,,,,,,, as we all know
something had to occur for it to happen, IMO we'll have to wait till he starts ripping wires off
and just seeing whats what.
Mudski for eg re-did a few earths and created more problems, and sounds similar to me
but on a smaller scale
hey guys sorry for not answering back, trust me i have already done that, that was one of the first thing i done was eliminate any after market wiring. and doka404 no there is no 3rd battery and sitting in cab the lhs battery is the 2nd battery in the loop. it goes to earth. i have replaced all positive and earth cable aswell as check resistance for each circuit no signs of shorts yet. im about to install the batteries and see if it was the cable if it hasnt fixed it ill share a video of it. cheers guys
