Good Evening All, I have combed through multiple websites and countless threads looking for some help or answers with this. I have a 52 Ford F1, 6 volt truck. Electrical has been gone through, new battery, parking lights, brake lights, headlights, dash light work, new regulator, rebuilt generator, replaced old bulbs etc. Never got the signals to work. At the time I had attributed to buried wiring The truck was a farm truck and had some hokey stuff done to it, but got most of it squared away now. Currently front clip is off the truck for various fixes and clean up.. Its still is runnable, electrical is intact except for headlights, front parking and signals. Heres the issue, with all the wiring checked out and cleaned up. And with a new flasher unit the signals still dont work, on the dash or the rear ones. I have also gone through the Napa X638 4 wire signal switch. That is clean and functioning properly, with a good ground. (Meter tested). I have 6.5 volts to the flasher unit on the X terminal, but only 4.5 on P. When I move the stick to activate a signal the dash bulb will light very dim, the rear lights show nothing. Rear lights are dual filament with brake lights wired seperately. The only bulb that light brightly is the indicator bulb in the signal switch it self. Nothing however flashes. I am curious if it is lack of load on the flasher, or maybe there is something I have missed that could be crossed up under the rear of the truck? Any thoughts? Any insight is greatly appreciated, Thanks Rick
Most likely suspect is bad ground. Is your truck bed grounded properly? Run a wire from the pick up box to the frame, and run a ground strap from the firewall to the engine. Have you checked to see if you have power to the socket contacts at the lamp are the lamp ***embly's grounded? Are your bulbs indexed correctly? Some six volt bayonet dual filiment bulbs can be inserted both ways. If one or more of the bulbs is lined up to the running light filement there may not be enough resistance to trip the flasher. Does your switch power through the brake light switch? On mine I have wired in auxillary lights for the rear signals (motor cycle signal fixtures) independent of the brake lights. I power the flasher from the accessory terminal of the ignition switch, my brake light switch is powered through a separate fused line from the battery side solenoid terminal. So rear factory lamps are run and stop and signals are seperate.
You probably have to hook up both signal bulbs up to have enough load to make your flasher work, if your grounds are good.
did you run the wires from your master cylinder (brake lights) through the t-sig switch then to the brake lights?
With the dual filament bulb, the brake lights and turn indicators should run on the same wire going to each bulb. Or maybe I reading the above statement incorrectly?
Help I have a 6 volt 1948 ford coupe. Brake lights work Tail lights work. BUT When I put turn signal on Both rear lights signal. Doesnt matter Left or Right Both rear lights flash. The incorrect light is a little weaker than the intended light. Also these lights are dim. The front signals are fine. Thank You.
Not quite sure how the lights are wired but a 4 wire unit does not have a brake light input. Check out this thread, post #5 and diagram C https://www.jalopyjournal.com/forum...wire-turnsignal-switch.1009372/#post-13973377 This setup should require separate turn signal lights. X= power in L- load (to switch) P=dash indicator
