So here's the situation I bought my sx nonrunning
All wires look with completely dead battery still hooked up
missing the key switch just has capped wires
It had no headlight but had the OEM plug for it
I started feeling with a voltage meter
good power to the battery but nothing to the headlight plug on any headlight setting
So I hard wired an off-road light I kept from parting a jeep a big ass light
It bolted nicely to what was left of the headlight mount
Worked great lit up everything
Many dependable hours with that setup
Then I slapped a 350x front end on the big light didn't work well so I grabbed a spare sx headlight and bought a fresh bulb
I had the bright idea of wiring it so the high and low beam were on at the same time
I used a car battery to find out which would do so worked great on the car battery
So I mount up the sx light (hard wired to the dead battery)
Fire her up and the light looks great I admire it for a few minutes then take off for a spin
The light turns blue then yellow then blue then dies
Burnt out
Thinking the bulb couldn't handle high and low beam at the same time I buy another bulb and wire it to only one filament (not sure high or low my)
Fire her up and the bulb burns out again
So what is possibly the problem with this setup
I'm thinking along the lines of voltage regulator bad or bypassed
I'm reading 10-20 volts to the battery and much more when revved
I see two routs
1 can I put a simple inline voltage regulator
2 is there likely a reason the key was removed or is it possible everything will work with a key
I am no electrician I need some help here
Yes I made sure not to touch the halogen bulbs during installation
