Title: parasidic draw
Post by: Happy Eeyore on February 24, 2026, 10:58:07 AM

If I connect a multimeter between the neg cable of the battery and a ground,  it shows about .16 volts with the key in the off position.  I see no reason for that and can find no wires which look damaged and i have looked carefully.  Any ideas.

You may have re-invented the antenna.

Disconnect the earth and put the meter on mA in series. Try 20A then 200ma etc in case you do have something leaking.

I need to patent that idea before the Chinese can steal my idea.  Did the amp check and got zero.

These don't pick up much RF. They were still in use when I was an apprentice. Big, heavy and reliable. Much like my greyhound.....

Analogue meters are better at something and are still very useful. I have my telecom multi meter and it gets a lot of use.
Sadly I missed out on getting an avo meter

I had a Model 8 Avo until one day I dropped it and destroyed the movement.

I cried  :'(
