So my 63 guide matic headlamps stay on low beam all the time. I have so far bypassed the system and everything works normal. I have been thru the trouble shooting in the manual but this is where the confusion begins.on my car when the power relay is powered I have low beam and when its not powered I have highbeam, this appears to be opposite what the diagnosis says should be correct.The wiring is all original and no wires have been mixed up.has anyone ever unplugged the 2 wire connector from their relay to see if it goes in to high or low beam. I have tested the relay ground and its good, I have tested the dimmer switch and its good. from working on cadillacs for over 30 years normally a gm wiring diagram shows the relay in a unpowered state which would put the system in low beam according to the wiring diagram on page 12-89 but gm may of had different rules in 1963. according to my cowl tag this option was not on the car when it left the factory, but was on the car when I got it 30 years ago. any help would be appreciated.
