AMM ohms....how far out is ruined? 200 1986

Generally, when measuring resistances below 15-20 ohms, you subtract the lead and probe contact resistance. (Obviously, if your measurements are thousands of ohms, then another half-ohm amounts to nothing.)

Your readings are a tad low. But before condemning the AMM, I'd make the same measurement on a different AMM (same type) for comparison.

I believe you're measuring the resistance of the platinum wire. It's hard to understand why its resistamce would drop (but not be zero) -- but easy to understand how it might go up or even be open (infinite).

Somewhere in my parts heaps, I have several AMM's from '85-'86 240s. I'll snoop and measure a few for you.
