Help finding a earth leakage

Thanks Tim. I’m only talking about -ve in the context of the negative battery terminal or pole. Shortening negative to -ve.

There is no volts or amps between -ve battery terminal and seat base.

The only way to measure current out of the battery is to disconnect the negative battery terminal and measure the amps, then milliamps if appropriate, by connecting the meter between the battery and the disconnected lead. The seat base should not come into the equation unless you're missing critical earth cables between the chassis, engine and body. Then you would need the volts setting and have loads switched on, e.g. the head lights and see where you have voltage drops.

Don’t the Perenties have a known wiring fault where the main loom runs through the fire wall and rubs through? I think more than one has burnt to the ground due to this - I’d be checking that carefully.

Thanks. When I rebuilt mine I routed the wiring on top of the chassis rail.

Apologies gents but idiot alert.
I had another look at the battery set up this morning. The earth lead was not connected to the battery but still tucked away in the back of the under seat box. I had only connected one end of the heavy cable that connects to the 2nd battery. So sparking is just normal when terminals are being connected.

I do have a slow current draw from somewhere which has flattened the battery, so will check across fuse terminals for voltage. And will try to find out what the fried wire was for and what caused the huge current draw through that wire.

You probably know this, but just in case you don't.
To measure the current (amps) you have to open the circuit and bridge the open circuit with your meter; put the meter in series, it's not like measuring the voltage .

Unless using a clamp meter designed for DC,which i have.

This makes reading current draw so much easier.

FFR or GS?

you can get some funny results if the radio batteries and 24v alternator arent set up properly.
