There's a 220 ohm resistor on the back of the cluster that is often the culprit. Here's more info:
Hey, good info. I didn't know about that. I'll have to check that. Hopefully that will be the culprit.
I have to be honest, the more I chase electrical gremlins for superficial items, the more I like my cars that have a total of 8 fuses for the whole car.
Glad to hear it. Small victories...
Crap, mine started flickering tonight.
I'd say pull the cluster and take a look. I bet its that resister that needs attention. Since I soldered mine, I haven't had an issue again.
BTW all the post regarding getting rid of the sensor by twisting the ends of both sensor wires together: no need to do so with brand new or not worn through sensors as the wire will still be in one piece. That's how the system works: wire wears through --> light switches on. Wire with continuity --> lights off.
quote from e30tech.com that describes it more precisely:
the indicator light illuminates when the sensor wire is either grounded or is broken.
When a sensor face first starts to wear against the rotor, the wire is
initially exposed and grounds against the rotor only when braking.
Later the wire is worn through, breaking the circuit. Thus the lamp is
initially illuminated only when braking, and later stays illuminated.
