Worked on finishing up the turn signals yesterday. Got the SD Turn signal controller installed behind my switch panel and wired it into the new spring-loaded switch. I have lights! But when I tried the hazards, things went very sideways. The hazards were not flashing at all…. just staying on as long as I held the switch.
The hazards don’t have to go through the SD unit, so I decided to return them to standard using the LED flasher and regular switch. Somehow, I was now powering into the keyed ignition system so that all the gauges were bouncing and even the fuel injection system was priming. But it was doing it at the tempo of the flashing hazards! And the key was off.
After sitting down and drawing things out in schematic, I figured that I had installed the TS controller between the TS switch and the hazard circuit connection… The hazards were attached to the controllers output. The hazards were powering through the TS controller outputs and probably the unit’s ground, back feeding everything on the car that has a ground.
So I removed the original wiring coming out of the hazard switch and installed it directly to the output terminals of the TS switch. This puts them before the controller, and attached to the controllers inputs. Success!!
I now have TS’s that only require a 2-4 second engagement of a spring loaded switch and turn off automatically. I have hazards that work from a momentary switch and will stay on until cancelled.
And those LEDS are nice and bright!
