How to program the ten-tap" programmable switch.

Your shogun does come equipped with a voltage regulator to protect your headlight, you shouldn't tap off the ignition circuit or directly off the alternator just for the reasons you listed, plus it can affect these systems unpredictably. Can you tap off the hot side of your horn before the switch, or taillight? If you tap off your headlight it would only work either in the high or low. Of course for the negative (-) side, grounding it any place on the frame is fine. Give these spots a try. Take care and enjoy your ride.

check the dimmer switch, I had the same problem. this dimmer switch didn`t dim on low beem but went out on high beams, turned the dimmer switch up and down/on and off and it came back on.

Hi, I have included a link to the instructions for the ten-tap programming.

sounds like the dimmer switch is going bad.

I have the same problem and I've tried two fixes so far and neither has worked.
- I replaced the daytime running light module and that didn't work
- I replaced the trun signal/hazard/light switch and that didn's work

I've had one comment that it could be a ground issue.
hope this saves you spending money on "fixes" that don't solve the problem
