Logic
IF HL ON
Foot switch is not powered unless headlights are on. AS IS Now. FS is SPDT with no off position.. Current plug will be disconnected. One lead will now go to activate relay1, the other position will be null, in essence making it an SPST on/off switch.
Relay1 is SPDT with no off position. In an inactivated position it supplies power to LO BEAM. When switched on, supplies power to HI BEAM.
Comments???
DRL, HL Buzzer, seatbelt buzzer, idiot light, and security starter disable circuits to follow. If logic on this one seems sound I will provide wiring diagram.
AGAIN. Comments, please.
