Hi Pete
Once you have everything connected run the heater on max. and test the voltage at the heater. It should be 11-12V.
While your at it, check all the 12v systems.
If the extension cable is too long, there may be a voltage drop.
If you are getting voltage drop, either shorten the cable or use 6mm cable designed for 12v systems (and then 240v 3 pin plugs won't work, you can't get the cable in).
