Wiring Latching Relay

[Railroad]

I would like to confirm the wiring on my latching relay. I am using this relay with my RT turn signal column. The dimmer is activated by the momentary switch on the end of the turn signal lever,,,, all really not relevant to the wiring.
I am not using the flash to pass relay.
I do have the RT diagram, but still would like to get it right.

Here is the diagram on the relay.

119439

I have the 56A to the brown high beam wires in the Ron F harness and the hi beam indicator display light.
I have the 56B to the red low beam wires
I will run the hot head light on, switch wire to 56 and a jumper from 56 to 30.
S will run to the momentary switch, which will complete closed to a ground.

I hope the wire from the headlight switch is designed to carry the draw of the headlights??

Here are the wiring diagrams that I used when I put mine together. They seem a bit confusing, but I sat down at the table and took some time to follow all the circuits and understand the process. It eventually all made sense. The wire colors are what I used, and are probably different that what you have. HTH. (I did use the flash to pass relay.)

You should be able to copy the image, save it to your computer, and print it out. Then you can make any notes you need.

Thanks for the input. I will get right on it.

I wired the latching relay and everything works right, except my hi beam indicator light. It is LED, if that makes any difference.

Pull the headlight switch and they come on, either hi or low, whichever way it is latched.
I hit the dimmer switch and the lights change, but the indicator, with a very slight flicker stays red.

I looked at the wiring and the wire from the indicator is lugged with the brown high beam wires on the latching relay.

The only thing that comes to mind is one headlight may be wired incorrectly. Would that do it?
It was daylight and I had the garage door open with no helper. I was watching only one headlight to confirm the function. Do not know if that would do it.

Looking for suggestions. Try not to make me feel too stupid. I am getting where I can do some mixed up things.

I, as most I think, use a blue light for the high beam. Your choice though. Other than that, I have LED's for all 4 of my dash indicator lights with no problems. The old incandescent lights were just too dim for daylight driving. The LED's are much brighter, but can be a bit too bright for night driving.

If your LED flickers momentarily, could be a bad ground on the LED. Try putting 12V to the LED indicator to make sure it works. A Power Probe is a great tool for this kind of stuff. It's sort of a continuity checker, ground checker, power checker, ground source, and power source all in one tool. There's a Power Probe 3 and a 4. There are many different accessory packages as well. Plus, now I see a lot of knockoff units too. I keep one in the car. https://www.amazon.com/Power-Probe-III-Clamshell-Automotive/dp/B00G4YUWMC/ref=sr_1_5?crid=3FKLRSH9WY00M&keywords=power+probe+3&qid=1577418374&sprefix=power+probe%2Caps%2C207&sr=8-5

One more thing. The LED's that I am using are not compatible with 12V, so I had to put in a little resistor to make them work with 12V. I would have to get deep into my notes to figure out all the details and numbers for them.

The hi beam LED indicator is inside my Speedhut speedo. I sent it back to them and had the turn sig and hi beam indicator installed.
The flicker occurs when I change from hi to low or low to hi.
I think I can pull the high beam wires off the latching relay and see if that terminal on the relay has any power when the lights are on low beam.
That should tell me, if it is internal on the relay or feed back from my wiring.
Thanks for the tip on the power probe. I definitely need one of those.

Well, I had time to work on the headlight hi beam indicator.
To bring everyone up to date, it is an LED lamp, inside the Speedhut speedo.
I am using RT VW steering column and the momentary switch on the end of the turn signal lever, with a latching relay to control hi and low beam.
Head lights come on and go hi and low with no issues, except 1 little issue, later on that.
To make it short, on low beam, the headlights back feed 8.33 volts on the high beam feed wires. These wires are tapped into for the hi beam indicator light. This 8 volts makes the indicator light stay on all the time.
I put 2 separate bulbs on the head light plug. One on the low beam and one on the high beam. No back feed and everything works OK.
I did not know the high beam filament could back feet voltage on low beam.
The only solution I know is a diode spliced in on the hi beam wires, diode, indicator wire, to relay.
I have very little knowledge about diodes other than they are 1 way conductors.
I would think 20 amp, 12 volt will do, if anything like that exist.
If there is an easier way, or I am misdiagnosing this, please advise.

The other minor problem is the pass side head light is dimmer than the drivers. With my little electrical knowledge, I think this might be a poor ground. Any suggestions on this, also welcomed.

I am almost ready for insurance and registration. I would like to get this sorted out prior to inspection.

Thanks,

There should be no back feed that I know of. Sounds a bit like a wiring issue, either a bad ground, or crossed wires. Check the socket wiring again. Possibly a faulty bulb? If one light is dimmer, and a transient voltage, something is not correct. I would not go the diode route. Need to find the problem and fix that.

I agree with boat737 here, find your wiring issue, don't try to re-enginer a working wiring diagram by adding diodes where they are not called for.

FWIW, only "common" wire at the headlights HIGH and LOW elements is the ground wire. IF you had a bad ground, voltage would look to backfeed thru the other element if it was connected incorrectly and could provide a path back to ground - and would more-than-likely produce a dimmer light output due to the voltage trying to travel thru both elements.

Re=check your wiring from the source, one light at a time if necessary, to isolate the fault. Verify that any diodes you are using in the circuit are positioned in the right direction - diodes are "one-way" gates allowing voltage to flow in one direction only unless they are under-sized and being overloaded.

Thanks for advise. I put 4 headlight bulbs in and all had the same feedback voltage, 8.3 volts.
I will put a jumper ground on the dim side and see if I can find anything.
Good advise on addressing the dim bulb before the diode.
I ohmed out every wire, without finding any shorts.
I did make some permanent jumpers from the headlight circuit down to the parking lights.
,,,,will have to check my wiring.

Just doing some desk top checking, stumbled upon my mistake. I have the head light plug wired wrong.
I am pretty sure, I can unpin the weather pack plug on the back and correct it.
Thanks to all for keeping me on the right path.

[boat737]

Very good. It sounded like it could be an errant wire.

There is a little tool that makes pulling those Weather Pak pins easy. There are a couple different sizes, probably the larger, I can't remember. Lots of different styles. I use one with the screwdriver type handle.
