A steady 21 Vdc is at the wires to the modureg when flashed up, voltage doesn't vary with temperature changes as i thought it should do???

:? :?

Well which is it?

If you mean resistance drops then by how much. As i said make a few resistance checks at different temps say 20, 45 and 60 deg approx.

Then we can start thinking about the board...
