OBS cruise control quit

How so?

Assuming the two wires are positive and negative...

All it does is complete the circuit.

If you do have a bulb in there, it's not like it "protects" the circuit. It either completes the circuit, or it doesn't.

If you have a light bulb in there, it completes the circuit. If the bulb is burned out, the circuit doesn't get completed.

If you tie the wires together it completes the circuit. If you cut them and don't tie them together, the circuit doesn't get completed.


We aren't talking about some uber sensitive computer controlled circuit here... It's an OLD truck. No computer involved. Nary a logic circuit to confuse or short out...

On or off. Completed circuit, or non completed circuit. That's it.

Take a light bulb and connect it to your battery, it lights up and completes a circuit, now take a piece of wire and connect it across your battery and it completes a circuit, which one blows up in your face?

Only difference between my example and the truck is the truck has a switch and fuse in series and the fuse will blow if you tie the wires together.

The light bulb in a circuit will only allow so much current through where as tying the wires together will let “unlimited” current flow aka wire melting current. Every circuit needs a load, be it a light bulb, resistor, motor ect... replace that load with a piece of wire and you have a short circuit and your wire now becomes the load and goes ****!

True. Good point.

But I would think it would blow the fuse. Not short out the brake lights.

Still a very good point. My suggestion then, would be to put a resistor in the line. Or, a light bulb. (Paint it black or something. )

I hope your not saying to take the 3rd brake light wires and tie them together as that will short out your brake lights and blow the fuse every time you press the brakes.

That's what I was thinking, but after pondering it a bit longer...
Please correct me if I'm wrong. I'm thinking that each brake light is it's own parallel circuit, and if you removed the bulb and tied any of the the wires together on any of them, you'd blow the fuse when you tripped the switch. Is there a way to eliminate the third brake light circut completely? I'm not ever going to run without a cap and I'd prefer to never have to deal with it again. Thanks for your help!

Correct, you have 3 parallel brake light circuits. You don’t have to do anything with the third brake light circuit, just put one end of a resistor to the green wire on the brake switch and the other end of the resistor to ground. This is exactly how the third brake light is hooked up and will solve a dead third brake light bulb issue.

Note-this is also one way to allow you to run leds without having to hack up your tail light harness.

Thanks. You Rock
Just to to be clear, the green wire on the pedal switch, correct?
In regards to running LED bulbs, just the resistor and a LED compatible flasher and I'm gtg?

 

[saburai]

Something like this will work, correct?
I know I can go much cheaper, but this one is easy....

Yes the green wire on the switch and a led flasher and your good to go.

That will work and you only need to use one resistor
