Title: Add a Head Light Relay Circiuit
Post by: Cameron 77C3 on June 28, 2006, 12:05:02 PM

Found this on another site.

One note though.  Do Not use the jumper option.  That is not quite correct but the rest is.

I was about to ask what's wrong with the jumper option, but i think i figured it out.

  Is it that your dimmer switch would now be trying to power the high beam directly from a low capacity circuit thus possibly blowing a fuse or burning out the wiring?

  If so, wouldn't a large diode ( such as in my invisible auto resetting killswitch on the 4by ) sort out this problem??

Yes, the problem is the dimmer switch, as labeled on drawing (low/high beam switch or dip switch), when on low beam the high beam comes on via the dimmer switch.  Hence dimmer switch carrys full load current.  A diode in the jumper would resolve the problem of the back feed.
