Turn Signals for Collector Classic Cars: Turnswitch from S&M Electro-Tech — Page 2

Integrating a turn signal system such as S&M's Turn Switch into your collector car can be challenging depending on the lamps and lights you have available and how far you are willing to deviate from the original. This is usually directly related to the vintage of the car. In general, the older the car, the less lights were offered by the manufacturer. Cars of the late teens through the late 1920's fall into this category.

Turn Switch controller connections:

  1. Power — Either positive or negative
  2. Ground — Either positive or negative ground
  3. Right Switch — This is the lead included in the wiring harness that goes to the arm on the steering column. It is connected using the three prong Molex connector (supplied with the kit).
  4. Left Switch — This is the lead included in the wiring harness that goes to the arm on the steering column. It is connected using the three prong Molex connector (supplied with the kit).
  5. Right Parking Lamp — Wire connection to the right parking lamp.
  6. Right Brake Lamp — Wire connection to the right brake lamp.
  7. Brake switch — Wire connection to the brake switch.
  8. Left Brake Lamp — Wire connection to the left brake lamp.
  9. Left Parking Lamp — Wire connection to the left parking lamp.
  10. Parking Light Switch — Wire connection to the light switch (parking or running light terminal.

Problem: Only one tail light is present on the car. Model L Lincolns are a good example of this situation where up to 1930, Lincoln only offered one tail light on the driver's side. Packard's as late as the fourth & fifth series also fall into this category.

Possible solution #1. Create a separate tail light for the missing side. Use a similar tail light assembly correct for the given year and adapt it in a manner similar to the original. This may include a special frame bracket and stanchion. This approach would preserve as much as possible the original appearance, but admittedly is the most complicated. It is likely adding the extra tail light would cost more than the whole turn signal system.

Possible solution #2. Add small accessory lamps to the bumpers either permanently or for temporary use using a clamp method or even Velcro straps. This is the least elegant and least costly solution, but may be good enough if the intent is to remove the extra lamps when participating in a judged meet.

Problem: No cowl lights present.

Possible solution #1. Small running lights may be present in the headlights that may be considered as turn signal lights.

Possible solution #2. Add small accessory lamps to the bumpers similar to the method as the tail lights.

Summary/Notes

  1. The Turnswitch is designed to self cancel itself after 15 seconds. This is setting is adjustable from 15 to 60 seconds. The driver can also cancel by momentarily switching to the opposite direction.
  2. The Turnswitch includes an audible indicator inside the controller. It can be turned on or off using the procedure in the manual.
  3. The unit operates on 6 or 12 volts, either positive or negative ground.
  4. If the audible indicator is not enough, a separate visual indicator (not included in the kit) can be included and mounted using a magnet or other means (see Photo3). The manual supplied provides information on how a customer can include this feature.
  5. The latest version will fail-safe with the brake and park lights still functional, even without power to the controller. (Note: your cars brake lights, brake switch, wiring and lamps must still be good).
  6. Can now use any type of momentary contact switch(s) to initiate or cancel a turn (You do not have to use our switch).
  7. All input signals to the control are optically isolated from the car wiring for improved noise rejection (e.g. ignition noise).
  8. Single plug wiring harness connector to control should the control need service or replacement.
  9. Adjustable self cancel. Will only cancel after preset time and lack of brake signal. (Time out is paused whenever the brake lights are on.)
  10. Still shares single filament park lights with front turn function. No need to use double filament lamps
  11. Hazard 4-way flash function by holding the signal switch in a left turn for 3 flash cycles. Flash rate is constant rate regardless of lamp type — LED or incandescent lamps.
