1980 Spider - Turn Signalling

Post by dodgydon63 » Fri Jul 12, 2019 9:00 am

My Spider has issues with the turn signalling mechanism and the lights on the instrument panel.

1) The indicator lights on the instrument panel are both always on and only go out (both) as you indicate. Is this easy to fix?
2) The indicators do not self cancel - are they meant to? My manual (Brooklands Books) suggests they should but then is silent on how to test/fix......
3) The flasher is silent and whilst I suppose I could live with the above the silence means I often drive for miles having forgotten to cancel and then wonder why other drivers complain!! Where is the flasher and how easy would it be to replace? What are the part numbers?
4) The Brooklands Books manual is OK..... but not great - is there a better manual out there for a 1980 car?

Any help and advice (including parts information) much appreciated

Many thanks

Do the lamps work with the hazard switch on? All of the flashers run through the hazard switch, so if it runs the lights and the column switch does not then you may simply have a bad column switch. Given your description of the flashers not parking I know at least the little auto park switch is not correctly seated in your steering wheel hub; if you remove the steering wheel via the hub nut (the big one under the horn) you'll expose the neck of the column switch and it becomes easy to see how to align it.

Otherwise, the most common cause of all of these issues is the wrong flasher unit. The correct unit is not internally wired the same as the common "auto parts store" units. Buy the correct unit from autoricambi if at all suspect: https://autoricambi.us/products/flasher-relay

A secondary cause is the wrong bulbs and/or bad grounds to the signaling equipment. You can trace the ground wires using the diagrams in the library of this forum. The ground in the trunk, which controls both lamps, is known to be an issue if not clean and tight against the body.

As to a shop manual, the official FIAT shop manuals are available in the library. The brooklands book, by comparison, isn't very good.

The instrument panel turn signal (the double arrow) flashing both ways is in fact normal operation. Fiat figured you could tell which way you were signaling by looking at the stalk, and just needed a light to remind you that it was flashing.

They are supposed to self-cancel using a pin in the mechanism of the stalks. Aftermarket steering wheels can sometimes mess this up. Blinkeritis is indeed an annoying affliction.

I misunderstood that the blinkers weren’t working. Everything else applies but you can ignore the part about the hazards and grounding. Get a new flasher unit, and it’s located under the dash by the ignition switch.

Btw many European cars had a single indicator for flashers. My old vw and Audi’s were like this
