Last week I swapped out the ignition tumbler then started having electrical problems. I decided this weekend I would try to tackle them. BTW, I have a '74 2.0l FI. Here's the situation:
When I turn the ignition switch on, I don't get any power to the fuse panel nor the fuel pump nor the starter. Before swapping the tumbler, everything was working fine, except the headlights wouldn't raise. They would light up, but not pop up. So, I checked the wiring diagram. Here's my interpretation of the ignition switch..... 30 - power from the battery (red) X - headlight switch (red) 15 - fuse #9 (black) & seat belt warning light (red) P - starter S - seat belt warning w/buzzer(gray/brow) 50 - seat belt warning w/buzzer (yellow) I pulled the tumbler and checked for power at ignition plug #30 - good - 12v When I turn the key, I get power to fuse #9 (12v). Also the seat belt warning light comes on (the one in the dash above the vent controls). When I close the doors, the light doesn't lite up. The seat belt buzzer sounds, but stops when the doors are closed. Looking at the diagram, it appears that there should be power to the red wire at fuse #11. I checked and nothing. I decided to place a wire directly from the battery to the #11 fuse. When I installed this wire, my headlights raised and lit up. The fog lights worked. The windshield wipers worked. The turn signals worked. Is there suppose to be a direct connection between the battery and the fuse panel? And if so, where is the conection? I think the ignition switch is bad, but I swapped out (2) others that I have in my stash, but they didn't work either. Joe has suggested that I remove the ignition switch from the tumbler and use a small screwdriver to turn the switch, which I'll perform tomorrow. Any suggestion? BTW, I don't have internet connection at the shop, so I won't be able to check until tomorrow. -- Rob |

I can tell you that part of the panel is hot all the time.
