Not a master of the dark arts (aka a sparky ) but if oneGSF sender was faulty perhaps the whole batch was. The dalek caps are all iffy.

the switch should pass a current until 60 deg C
that's when it turns off the heaters (Carb choke and manifold)
the relay (No.1) is found in the junction box, in the engine bay (left bulkhead)

As an aside here, I have just set up a manual switch as I too suffered with no heater.
With the syncro thermostat housing that came with the new engine, I can't fit the proper push in with a clip thermo switch.
unless I get off my ars* and fit the proper housing

ordered one from Brickwerks will try that if not will fit manual switch on dash....

[telsony]

fitted new one today from Brickwerks still not working,,,lost?

[kevtherev]

have you checked the continuity across the switch?

i.e. does it pass a current when cold?

[telsony]

no.but there is current to connector bot not across switch?

[kevtherev]

there should be..
either it's the switch or the connectors

have you a curcuit tester, like one that beeps, when you check a switch across it's unconnected terminals?

[telsony]

when switch in hot water power across.working wrong way round,,,,?
