I fired up my dash panel the other day, with nothing else attached,
and the red LED still flashed for about 5 seconds.
(With or without the 42 / 43 control unit connected.

1983 Tin Top with a poorly DF and 4 speed DT box.
1987 Electrics and a DJ engine.
Maybe one day I might get it finished

That will be the capacitor charging and discharging to perform the test then, not sure if that would happen id the rest of the circuit is plugged in and taking the load . Mine wouldn’t self test with the control disconnected iirc

Hmmm, so I'm still none the wiser
I don't suppose anyone knows which wire, or trace connection on the flexy ribbon PCB behind the cluster is the led feed so I can test for a signal?

The temp gauge led is controlled by a circuit in the gauge itself. The circuit can be triggered by earth faults and voltage changes.MoritzTheDoka wrote: ↑21 Apr 2021, 18:20 Hmmm, so I'm still none the wiser

module 43 (or 42 as there are two types) sends a series of pulses to the circuit inside the temp gauge, these pulses trigger the led and continue until the ignition is switched off. If your temp gauge led is flashing intermittently while you are driving it is unlikely to be the module 42/43.

No, as mentioned above... It doesn't work at all... Ever.
Not on start, not when the temp sender is bridged, not when the coolant level sensor is removed - never

Gauge out and test the actual led then I would say ...

Re: Electrical? Mechanical? Overheating no fan, no idea
I think that's the way forward
One slightly more broken gauge coming up!
