Hmmm, interesting - I would be happy to try it with the Ammeter on the bench. Swapping the supply (Y/B) and ignition feed (W/P) connections hasn't reversed the polarity, but that would be because it's still grounded, so the electrons have somewhere to run. I'll definitely involve my auto leccy mate, and report back.
I also have 2 spares, thanks.

No stock now though Mark.

that is a bit puzzling --if the oil is up to temp then you'd think the oil going to the cooler would be as well---have you got a pic. to share of your hoes /thermostat/cooler layout---

Worst case ... I have 2 -20+20 ammeters on the shelf in stock to replace yours.

Apparently yes a DC ammeter CAN become polarity sensitive!

As to changing the polarity, I found this below. Cant say I understand it at all ... but here goes.

Anam,

promised to let you know how the reconditioned shocks from V&C Engineering performed.
Finally fitted them, along with Superpro bushes (a faff as we all know) and an Austin Healey Sprite & Midget Top Trunnion Needle Roller Bearing Upgrade Kit (easy).
The ride and handling are much improved. More controlled, no crashing over bad bumps, a significant improvement. So can recommend V...

The boiling point of water is 100C and you might expect your oil thermostat to open at 80C. If without a stat the oil pipes are still cold either you have the stat on the wrong way around or you have a blocked pipe.

Maybe we need a new thread on old gas. I have a '72 MGB, a '62 MGA and a '53 TD. I drive at least one at least 100 miles every week but that means that the each sit on average for 2 to 3 weeks and occasionally one will sit for over a month. I use E-10 gas because I burn it up pretty fast. They all start pretty quickly. Turn the key, listen 'til the clicking slows and hit the starter. The TD ...

I think I was misled by the diff allowing the opposite rear wheel to rotate when the car was in gear and the clutch pedal released. I am now wondering whether the release fork is bent.

Under the chassis hoop and on top of the steering column.
