Need help on 6 V semaphore

[bedjo78]

Hai All,

I just buy oval, has been converted to 12 volts. Now I have 6 volts semaphore, I need help how can I install them.
have been searching how...but i don't have an answer that clear enough.

I found a converter from cip1.com. Is this converter will work? how It wired?

Thank a lot

regards

That "converter" from CIP1 is just a high power resistor. Each 6V electrical item you want run on 12V will require a resistor of a different value. Since they don't tell you the resistance of that resistor, one can only assume it works only on wiper motors.

Instead of getting that, go down to your local electrical supply store and buy a 1.0 ohm, 50 Watt power resistor. It will look exactly like the one in your CIP1 link. 1.0 ohms is the size that makes the semaphore see exactly 6V. Some guys like their semaphores to snap up quicker, so if that is you, get a 0.9 ohm 50 Watt resistor. That will give the semaphore a bit more voltage.

Whichever one you get, you must mount it onto some kind of heat sink.

It looks like it should work, the wire that goes to your switch/lever on your column has a live input which is then sent to either side semaphore when you move it up or down. So I would think if you traced that wire and fitted the converter so only 6v is getting to the column switch all should be well - check the wiring diagram on this site for further information.

If you want to run several 6V items off a single supply, a rather more robust solution is something like this :

I just want to convert on Semaphores only, all other stuff is already 12 Volts. So I'll go to the cheapest option.
I'l try to find the resistor in local store first, If can not find..then will ordering from cip1.com

Thank a lot guys

best regards from Indonesia

I run 12v through my semaphores with no problems, just switch to a 12v bulb

Is the Solenoid not get burn?
I just want to be carefull with that cause this is NOS 6 volts, and bigmoney too.

thanks
best regards

Check the voltage at the semi-4 post. My Zwitter has it's original wire harness, I get 9.3 volts at the semi wire and have run my semis on the 12v system with 12v bulbs since '94

I just want to thank you, you found what I need to reduce the voltage going to my wipers

Yes my system is 12v and yes Bruce is correct. While most of my original harness has had terminals replaced / cleaned etc I left the turn signal circuit 100% alone. The only time I got smoke was after the first few times I used them and I attributed it to the oil I used to ease their old hinges etc. They haven't smoked in years now.

You might think that if you double the voltage in the semaphore, you will create double the heat in the windings. Not so. Follow along with some help from Georg Ohm.

V=IxR
A semaphore's resistance is 1 ohm. Apply 6V to it, you get 6Amps of current flowing through the winding because of this equation:
I = V/R = 6V/1ohm = 6A

The power in a cct is found using the following:
P=IxV, in our case, P = 6V x 6A = 36W.

Now hit it with 12V. The resistance is still 1 ohm. I = 12V/1ohm = 12A.

The new power being dissipated is now P = 12V x 12A = 144W.

By pumping 12V through your semaphores, you are creating 4 times the heat in the windings. It is no wonder they start to smoke in less than 1 min.

[Alan Willis]

I find flaws in your calculation; if the draw on the semaphore is now 12A then how come the 8A fuse doesn't pop even when I have the brakes applied? True the solenoid will get hot if left on too long, but I havent had a problem yet. As for leaving the bulbs 6v in a 12v car; the FILAMENT can't handle it. Its the same as running 12v through a 6v starter;its been done for years with no problems.

I'm running a 12v system in one of my cars. Haven't burned a semaphore yet either. But at the same time, I don't have the semaphore lit up for more than 15-20 seconds at a time. I know it'll fry if I have it up for too long, so I'll aviod that problem all together.

Put in a six volt battery and run them seperately from the rest of the car.

A 12 volt battery is a group of six two volt cells. They are connected inside the case by lead bars between each cell. So a 12 volt battery is really six two volt batterys connected together in series.
Drill a small hole through the top of the case into the connecter bar between the third and forth cell, and connect a wire (with an eyelet) with a sheetmetal screw. Use an inline fuse holder, and run this wire to your six volt item. Ground the item to complete the circut.
I learned this from an engineer at a battery manufacturing plant 35 years ago.
