Hazards on: light on hazard switch flashes, as does the indicator tell-tale on dash. If you indicate, you just get one flash from the dash tell-tale, while the actual indicators work fine (complete with nice steady ticking sound). The lack of tell-tale is MOT failure (or will be anyway).
Things I've tried:
All earths.
All indicator bulb resistances and connections.
Swapped tell tale for the main beam one (that works fine): still the same.
Rev counter (where the tell-tale lives) earth.
Connection between flasher unit and tell tale: I'm assuming the indicator switch itself must be O.K. as the indicators are flashing.
Two different flasher units.
Voltage and earth at flasher unit.
General wiring around flasher unit, indicator switch, and hazard switch.
Seems odd that the tell tale works fine with the hazards, and yet the same tell tale running through the same flasher unit does not work with the indicators, other than the one flash
If the 914 had seperate left and right tell tales, I would just bypass the existing wiring and hard wire the tell tale to each indicator circuit, but it only has one bulb for both.
Having spent over eight hours on this, on the drive in the cold wind (garage full: nice timing
), I'm running low on ideas .... any thoughts?BTW, with the cover off of the flasher unit, it is of the older style, with two solenoids: a larger one for the flashers, and a little one for the tell tale. You can actually see the small one just work once, and then stop, almost as if something has broken the circuit. I would buy another one, but having already bought one new one that behaves in just the same way, I thought I would try here first.
I'm getting jittery as V/World is fast looming, and time is getting tight
