turn the meter dial to resitance
a set of numbers like 2K 2M 20m that have this synbol

when you touch the leads of the meter together, and the meter reads ZERO or super low number, ZERO aka zero resistance "complete continuity/dead short"
infinity is when you touch the leads to something and it reads a really high number, high resistance like 200 megahoms,
when trying to find a pinched wired , a high resistance reading say 2000 ohms (beeper won't beep) where it should be infinity,, means you have a leak to ground where the other probe is touching (frame ground)
a reading of infinity (super high number) means no connection to ground, move on check the next wire
Glad you found your problem
I used both a volt meter and a continuity tool that had a bulb that should light up if anything went to ground. I will say I am not known by the name Mr Wizard so I suspect you are light years ahead of me. I don't know what you mean by a reading of infinity. If you could give an explanation it would be very helpful. You guys are great. I am more of a wood guru and any help is appreciated.
