Fog light switch/power take-off

Post by murr57 »



Just discovered that my fog lights won't come on when switch is depressed and that there is no power coming from the power outlet in the left side compartment. Any chance that they both run through the side fuse or relay?

Did you test with High Beams on? If yes, that is a normal situation. Test the lights while you have only the Low Beams on.

Thought you were on to something there. When I went to check on your suggestion I noticed that the fog lights flickered on momentarily as I switched from high beam to low beam but unfortunately that's all they did, and then they stayed off.

It may be the switch that is faulty. I've read about many failures.

Cyclemax has replacements.

The above link is to a show chrome switch. Cyclemax also has OEM switches.

It’s the switch or the high beam cutout relay under the fairing pocket. When the high beams are off, the relay is de-energized and the power for the fogs is connected through the relay’s normally closed contacts. When you turn on the high beams, their power energizes the relay opening the contacts and killing the power to the switch and the fog lights. The fog light power comes from the tail light circuit. This cutout is mandated in a lot of states that don’t allow fog lights along with high beams at the same time.

Thanks for your information Techdude. I'm new to this site and I see now that I'm using the 'search' engine that you've already answered this question for someone else previously. Thank you for taking the time to help me.

And now the follow-up. The fog light problem was a relay that needed to be replaced. And the power take-off plug had a broken contact in it so it had to be replaced. Nothing serious, the bike is 15 years old and these little things just happen. Thanks for everyone's input. I was pretty comfortable maintaining my VTX for the past 10 years but this is a whole new learning curve.
