torpedo resistor holder

[vi3901jc]

What color wires connect to each end of the blue torpedo resistor holder on the 1977 Fiat 124 spider? It is used on the lighting dimmer circuits, I think. Thanks for any help!

That might be the resistor holder under the dash for the overheat switch on top of the cylinder head (not the same as the sensor for the temperature gauge, but right next to it). If that's what it is, the wires are either green, green/white or green/black. Fiat was not always consistent in wire colors....

For what it's worth, the resistor is about 32 ohms.

Thanks, you were correct in the location and the wire coloring! The car is getting back together slowly but surely. I finally have all the wiring harness back in and everything is working except the turn signal dash indicator lights, but will check out that problem later. Thanks again, Norm

Didn’t even know that resistor existed until I looked closely at schematics. I then went exploring. I had never removed the fuse holder assembly before…never had any issues. On a 124 Coupe, there are three inline fuse holders behind the main fuse box. A large white twist-on, another smaller one and a 1/4 turn small black one. The black one had nothing in it. Maybe later I’ll trace it back.
