Brake Lights Not Working !!!

[francoblay1]

I was able to disconnect the bulb and test the wires. Brakes would still not work but the signal lights do. I'm trying to narrow down this problem but I'm turning crazy. Any other ideas or troubleshooting I can do?

Test the switches themselves??

When you apply front brake - rear brake - do you get continuity on the wires 24v and 0 ???? If not the switch isnt working. My guess would be short on rear brake wire and front is broke sensor??

Check all the grounds on the wire plus unit...i have fixed several bikes with parking and blinker issues cause they didnt work and it was a ground that wasnt hooked up during the wire plus installation...there is alot grounds...dont know if thats ur problem or not but hoping it might be

Sven gave the best answer for troubleshooting electrical issues.
Begin at rhe source/switch, and check continuity of the path/wire to the next connection, with a volt/ohm meter, to isolate or eliminate wiring as a potential issue.
The wire for the front brake circuit are notorious for breaking at the pin plug on the pc board on the hand contol.
If you have continuity in the wiring, then the actuator or end component should be suspect.

I know this can get to be a big pain. I looked at your post of the wire plus wiring dia. If you take apart plug #3 you should have 12volts
on pin 1 & 2 when the brake is applied. Pin 4 to ground is both brake switches.

I did this and there wasn't any current going through these pins.

how do you test the foot brake switch?

To be perfectly honest, I dont know, I'm following this thread to find that out myself, as I am experiencing the same issue myself. I've checked continuity of the wires, found the problem with the front (broken pcb pin) but still trying to diagnose the problem with the rear (foot) brake lights.

You need to check the rear brake switch on the caliper. Trace that wire to the connector. Open connector - Use Ohm meter on pins, have someone depress rear brake pedal. If you get conductivity, then trace wires from connector back to ehc for a broken wire.

If you grounded pin 4 and no power on pins 1 & 2. Then it is the relay either no hot going to it, or not working.

So I did this and I got 0.1ohms when I pressed the pedal

Then switch is good.

Switch is good but this was directed specifically at Big D Florida since he was trying to figure out REAR brake not working but front ok.

But it does eliminate on more thing. Next you need to get to the EHC/WP and ground the pin there and if lights fail then (assuming they are wired correctly) then the module is probably bad and you could fix with a relay.

which pin is the one I need to ground I'm a newbie with this system.

Like I said in this post, the plugs should be numbered. Find plug 3 take apart and with a volt meter red lead to pin 1 or 2 black lead to ground. Then take a jumper wire from ground to pin 4, you should have 12 volts on pins 1&2. If not the relay is not working or maybe the hot wire going to it is broken?

When I had the wire plus system on my 04 Chopper, (what a mess) I lost my rear taillights. Found out one of the wires came out of the plug. There are so many wires to deal with on a wire plus. Anyone of them could not be crimped right or not installed in the plug all the way. To me it was the worse replacement you could of bought. But back then that's all they offered.
