Mystery wires

[Jev88]

I appreciate this is rather difficult to diagnose remotely!

Replaced a tired old underpowered inverter in my RV, that sits above the leisure battery bank.

One wire that disappears into a small cable protection sleeve used to be connected to the Positive on the battery.

I measured it today with multimeter (second connection to earth on chassis) and in DC mode flutters positive and negative readings 30 millivolts.


Flick over to AC mode WITHOUT second probe touching chassis earth and reads steady 8 volts.
Now touch second probe to Earth and get a steady 44.9 volts.

What the heck might this wire be for and therefore doing?

Scratching my head now.

It's connected to Bill gates all-seeing transmitter. He uses it to get a stronger signal from the micro-dot cells injected with your covid jab. You have to wear a tin-foil hat to block it.

I was told tin foil pants were enough.

Only if you had your jab in the bvm!

I have tested the same wires now with an older multimeter and it sees nothing!! I gather that apparently "cheaper" multimeters get fooled by the "ripple" effect of some inverters?
Now home I also traced these mystery wires through a small protected loom to front of engine and they snake up and go right through a small grommet into the black hole that is the back of a dashboard..... Still non the wiser what these wires are for.
Although it did occur to me that I don't know how/if my RV charges the leisure batteries?
