Was taking our newly restored 73 2.0 out for its second attempt and although the car is not dialed in yet (another challenge) we hit a problem when turning on the fog lights. After 1-2 min with the fog lights on it started to smoke and I immediately turned off the switch and it stopped.
I am confident that the harness was good because Jeff restored it. Any ideas what might have happened to cause this? Thanks |

Hopefully none of the wiring harness got pinched or punctured in the process of reorganizing it, if I remember correctly the fog light RELAY'S power is fused, but the fog light SWITCH'S power isn't.
With the fog light switch lamp not lighting up when it's turned on, I'm wondering if the Grey/Red wire going from the fog light switch to the fog light relay's coil is pinched or otherwise shorting out, dragging the voltage down so low that the switch can't light, but it's still enough to trigger the relay. |
