This must have something to do with pos. grounding. swapping the power and ground leads allows the relay to switch.....but then the lights don't go on.
I think I will skip this whole endeavor until I eventually convert to neg. grounding. At least I learned a lot about vehicle electrical...

Yes fuses are fine...and pins are linked.
However...
I tried flipping the relay with a 9 volt battery. It works. Tried the other relay I started off with. It works!
But neither work in the vehicle....or even when just using the vehicle's 12 volt battery directly (no vehicle wiring).
Ideas?
Okay.... new dimmer relay as used in old VW bug and wired in as shown in diagram above. Headlight goes on but grounding the switch lead has no effect....that is, there is no change to high beam.
Ground is good
Continuity is good between the relay and the bulb for both leads (high and low)...
Thanks.
Knowing that it was a pos. ground, I switched the power and ground leads. I don't think I originally set it up as in the directions (neg. ground) but, at some point I did switch I did switch the + - leads and blew a fuse. Could I have fried the relay?
I'm still trying to make this...
The relay I got has 6 leads.
Red-12 volt from light switch
Black- ground
White - low beam
Yellow - high beam
Then two orange wires. Instructions list these orange leads as going to a switch..... But connecting to the poles of a switch does not produce any effect.
I tried running a...
Thanks for replying.
Just a way to toggle between high and lo beam with a momentary.
I now understand that I'll need a relay. I found a source for a solid state relay, but not sure of the hook-up....which wires connect to what.
From the photo, I see at least 5 wires - red, black, white, yellow...
I have a micro push button momentary switch. I want to use it on a vintage motorcycle ( 12 volt) to switch between high and low headlamp beams. That is, to change its use from on/off to a to position switch. Can this be done? To be clear, the beams are not additive -- the low needs to go off...
