24 volt dosimeter(same as Clansman?) connectors which is + and which is -

Question

I canny find oot which of these pins is +ve and which is negative on this connector

The connectors are for a dosimeter BUT the part numbers 6665-99-225-2221 and 6665-99-225-2220 seem to get me to a clansman connector.

The device has the letters PLA and 24V on it.

Where might I find out which is +ve and which negative.

 

The land-rover 2-pin connector does not seem KEYED!  that is strange in my eyes, or does it not matter which pin in which for a dosimeter?

The connectors have A and B on them and a chevron below the B connector.  I think I say something somewhere that suggests the B is positive.

All help appreciated.

The rectangular connector is for a remote lead from a clansman battery to the radio. Used in cold weather so that the battery could go inside the operator's clothing to keep it warm. As shown the upper terminal is positive. It screws onto the battery. The circular connector  is I think the general power connector in vehicles. Not used on radios.

Aye that is great thanks.  I hooked up a current limited PSU attached as suggested and the unit works fine.  

However it does show that my PSU voltage overreads a little - or that I have voltage drop in the cables!

Thanks again.
