Warning lights on the dashboard

Hello Rover folks,

i have a specific question about two problems regarding my dashboard lights. I removed the cover and checked the printed circuit board and the bulbs. These are the results of the german jury:

- Choke warning light: Does not work at the moment, bulb is OK. How would one try to start systematically and fix this? The choke itself is manual and working fine.

- Ignitition light: Does not work, the reason is a big chunk of the respective conductor path missing on the pcb. Is soldering a little cable between the connection points an option? That would be my first try. Might be a bit difficult with the instrument panel in place and only the cover removed. Certainly above my soldering skills...

These are minor problems, but everything else is sorted out and the car is otherwise running perfectly.

Any hint is welcome.

Choke Warning Light- Switch on the ignition, pull out the choke, and then earth the Otter temp switch on the inlet manifold and see if the light comes on, if it does then the Otter switch is faulty, if not, then, with the otter switch still earthed, check there's a feed to the switch on the cable behind the centre console, if not then that's the problem, if there is then join the two wires together, if the light comes on then the choke switch is faulty.

Bridging the PCB where it's broken shouldn't cause any problems, and could cure the problem with the Ignition Light.
 
There a silver filled epoxy available - sorry don't know where from but it is a Loctite product.

This can be painted onto the circuit board to replace the broken conductor.

Also used to paint onto broken rear windscreen heater elements.
 
That sounds interesting, never heard of that. I will google it up. But I am afraid since a good chunk of the conductor path is missing (at least 15 cm), a soldered little cable would be a better solution.
But thanks for the information, learned something again.

Olaf,

Before you solder a piece of wire to bridge the broken track carefully rub the old track ends to clear away any lacquer or shellac which may have been sprayed on to protect the board. It will make soldering easier.
