[QUOTE="machoheadgames, post: 434380, member: 18789"] High beam power comes from the dimmer switch on the steering column which is operated by a rod attached to the turn signal/high beam stalk. The dimmer switch gets power all the time jumpered from the headlight switch so that you can flash your high beams. Your dimmer switch is likely bad and allowing that battery power to flow through the switch when you are not flashing the high beam. I would try a new dimmer switch or at the very least test the output on the high beam wire from the dimmer switch. I suspect you’ll find some voltage there which shouldn’t be unless you are holding the turn signal stalk down to flash, or you have the headlights on and triggered high beams on. Edit: I just re-read and see that you already replaced dimmer switch….hmmmm. I can not think of how else power would be making it’s way down there after looking at the circuit… [ATTACH type="full" alt="0B5C1FD5-B311-4710-88A0-B69235133DF7.jpeg"]119658[/ATTACH] [/QUOTE]
