more wiring question

Post by 69veedub »

How can I wire my Head lites and brite lites, my wiper motor, and my emergancy flasher to toggle switches. I have a 69 beetle ( baja ). and still running the genarator. I would be happy for any help. A web site or anything with drawings I could look at.

Thanks Jeff

I actually did a circuit for someone for the wiper.
It is quite involved!
Looks like this:

The headlights would be fairly simple.
You want to get heavy-duty toggles for this.

The Hazards switch would also be a bit complicated,
but doable.

E-mail me with what you had in mind and we'll work
something out if you like.

Speedy Jim Thanks for the info, I'm not a wiring expert so you'll have to bear with me. I Would like to wire the headlits so all I have to do is flip the toggle switch up and the lites come and if need be flip another one on for the bright lites. So that would be 2 switches. I would need another one to turn on the running lites. The reason for using toggles switches is the dash has been cut were the orignal switches go. I have made a cover plate for the hole and have drilled it for toggle switches.
The wipers would need to be like your drawing, but not being an expert in the electrial field its hard to follow. I do know its a double throw/double pole but, Were are the wires coming from and which wires are they. Will the wiper work on a single pole toggle switch. Will the head lites also have to be a DP/DT switch or can they be put on a single pole switch.

Thanks Jeff

Speedy here is is how I see this wiper motor hooking up to the DP/DT toggle switch Let me know If i'm wrong. Looking at it from the way its drawn out.
Top left blk/yell from 53b*** Top right Brown from 31
Middle left blk/gry from 53a *** Middle right blk from 30
Bottom left blk from 53 *** Bottom right Brown from 31

Thanks Jeff

That was for this diagram?

Upper and lower right go to relay coil.
Center left goes to relay contact.

Speedy were do I get the relay or is it on the car. I told you i'm not a smart man when it comes to wiring. Can this be bought at radio shack .

thanks Jeff

I am going to resurrect this thread because I have a few questions as to how this circuit works. I am hoping that I can make this work using a single dash-mounted switch, which activates a relay or two, which will properly close/open connections as needed.

I am going to reference a very popular diagram, which I have a few questions about, which I will add to the original diagram for my sake. The original circuit comes from this website, http://nls.net/mp/volks/schem/wiper2.htm. It is copyrighted to J. Mais, so I hope that this cross-link and adaptation is acceptable.

The first question, Does this diagram represent the use to two separate switches? In the areas that I have highlighted with RED and GREEN seem to represent switches in both locations. Am I reading this correctly, that based on this layout, I would need to have two switches to have this circuit work correctly?

The Second question, What is going on with the dashed line that I have highlighted in YELLOW? Does this connect the ground at the OFF position?

Dashed lines, by convention, indicate a mechanical connection (not a wire). The contacts shown at both ends of your yellowed dashed line are all inside the stock dash-mounted wiper switch, it's just been drawn on this schematic as being in two locations for the sake of clarity when analyzing the circuit. In other words, the pink-shaded "switch #1" and the blue-shaded "switch #2" are both inside the stock wiper switch. If you were to try to duplicate the function of the stock switch with two independent toggle switches the "pink" one could be a commonly available single-pole, single-throw switch but the "blue" one would need to be triple-throw, and that's not a common item. The pink switch would need to always be open until the blue switch was in the "off" position, because if it were shut while the blue switch was in a run position you'd have a short to ground which'd pop the fuse every time the wipers came to the park position.
This is where relays enter the picture, they can be used to make simple toggle switches accomplish the more elaborate functions of the stock switch.
Now, if you don't care about having the wipers park on their own and will settle for just manually turning them off at the right moment, you can simplify the wiring dramatically. Forget about the pink switch and its wire to 31b on the motor, forget about the black/purple-stripe 53a wire, and use a simple/common single-pole double-throw center-off toggle for the blue switch. High would be with the toggle handle up, low with it down, and off in the center.
Now, if you could find a double-pole, triple-throw switch that could handle the current it could be wired in thusly:

...problem is, about the only DP3T switches around are made for electric guitars and aren't robust enough for this job.

If you were to use another double-throw, center-off switch for the headlights it'd just be up for Hi beam, down for Lo, and center off....but you'd need a second switch to run the taillights, and you'd need to remember to use it.
OR, use one single-pole on/off switch to feed both the taillights and the input of a second double-throw (no off) switch which would be used to select either Hi or Lo beam.
Either way's pretty crude and a bit awkward when the need arises to dim the headlamps for approaching traffic (without turning off the taillights and/or turning on the wipers should you hit the wrong toggle) but they'd get the basic job done.

A `69 should have a factory relay that does a dandy job of selecting headlamp Hi/Lo when triggered by the momentary switch actuated by the t'signal lever. My first choice would be to make use of those components, then you'd only need one SPST toggle to turn the head & tail lights on.

If you want to be able to turn the tail, and maybe front parking, lamps on without the headlights as the stock light switch does, you'll need a double-pole, double-throw center-off switch (one side for the headlamps and one for the taillamps)...up could be head & tail, down for tail/parking.
