Hi y'all,
Meant to do a welcome thread, but have been consumed troubleshooting electrical gremlins. I just acquired a 69 FJ40V in relatively good condition, however I've experienced some 'changing' problems related to the turn signals.
When I got the vehicle, I noticed that the FR and RL turn signals worked, but only when holding the turn stick all the way down (for left) or up (for right). The RR and and FL signals do not flash. All lamps will light, and still do.
I'd been seeing some inconsistent behavior, like the fuel meter would not work all the time and the wipers basically flying off the windshield some times they were engaged.
Something else that changed during the troubleshooting run was that whenever the turn stick was moved fully up or down, both the FR and RL turn signals would flash (but never the other two).
I noticed the FR signal lamp was less bright, and suspected bad ground. Began hunting for some problems and corrected a bad splice. No change. I was looking the distribution block in the front right of engine compartment and checked voltage on the wires coming from the FR turn signal. ~11.5v on one side, 0v on the other. I moved the return wire up a screw and have full bright.
In the midst of all this wire jiggling and trying to see how things should be laid out and how to test, other components have gone inoperable - most importantly the brake lights (lamps are lit, but no effect from brake pedal).
The signal flasher is not making as pronounced a 'click' at this point, and since the previously working indicators won't flash I'm thinking I'll just grab a replacement flasher from NAPA to see if that improves any ops.
So currently, I have the following situations:
Operable
Still a little fuzzy on the right procedure and places to check for bad grounds. If there's a 101-level thread for electrical troubleshooting I'd appreciate any pointers.
EDIT: Should mention I checked fuse bank under dash, cleaned all contacts and replaced with known good (tested) fuses at correct amperage. Have found BLUE/RED wire that came off the wiper fuse and it's clean severed. Will be tracking that down to see if it was a jumper or something that should be connected elsewhere.
Thanks guys!

So currently, I have the following situations:
Operable
- Headlights
- Running lights
- RL turn signal
- Speedometer backlight
- Occasionally, the passenger side turn signal lamp in dash is lit when holding stick up
- Occasionally, the FD indicator lamp is lit
- Interior 'room' lamp
- License plate holder lamp
- Brake lights (lamps work, do not 'flash' when pedal is pressed)
- FL, FR, RR turn signals (lamps work, do not 'flash')
- Reverse light
- Hazards (switch does nothing)
