Turn Signal & Flasher Issue 1994 International Thomas Vista 6.7L DT 408
Hello, all I am experiencing a weird electrical gremlin and need some assistance I've included pics and will try to have a clear explanation of the problem.
My turn signals and hazards have always appropriately functioned, some marker lights and 2 brake lights were out on the back of my bus so I decided to change them and upgrade all marker lights etc to LED.
I changed all lights on the bus, the right marker on the rear (see pic with mark up) was not functioning so I went to check it with a multimeter. Not thinking I ended up in the brake light beside it by accident, while checking the small space my multi-meter prongs made contact and a small spark occurred. Note this was in the brake light not the turn signal.
ok so after I check the fuses for brake lights and it's fine, so I replace the lights and put things back and go to test my lights. Now I find all lights are functioning except the turn signals and hazards.
I get no clicking or lights when using right and left signal and hazards, but if I put the switch to left or right then put the hazards on and off I get 1 click and 1 flash from the signal on the side that the switch is set to.... ok?
So I start from scratch:
- Check grounds on all lights they all seem good and I am getting function from all brake and marker lights
- Check fuses they are good, 1 blown fuse for horn and fogs I replace that no change to function
- using the turn signal plus hazard to get 1 flash I test all lights and find all my turn signals are receiving power and lighting up
so I get a new mechanical clicker unit from the store, plug it in and now I cant even get 1 flash from anything, totally dead.
Back to Lordco and I swap the flasher for a new one, plug it in and now I get a steady dim light in all signals when using the hazards, and dim steady light in the corresponding side of signals when using the left and right signal..... no clicking or on-off action. If I switch back to the old clicker I again get 1 full brightness to click and light on all signals when using hazards or signals.
So I am stumped, it seems like the clicker unit is the problem as the switch is doing what it should and the change seems to come with the change of the mechanical clicker. I am going to go to Napa to check the clicker part again and see if they have a different brand.
Any ideas are welcome, I am totally stumped! Pics for the explanation of fuse panel, clickers and lights.
Thanks in advance guys, I have read other threads with similar issues but no fixes from those have helped me, I am very confused by the fact it worked one second then didn't with no direct cause, and that it still seems to partially work!
