To continue the thread of headlight issues, I have a photo attached of the plug which attached to the light switch on a 65 Mustang.
The three circles areas are confirmed as having power to them but the rest did not light up.
For context, neither my low beam or high beam work at the moment but park lights, brake lights, indicators and a couple of dash lights work.
The light switch is new. Replaced when I could only get high beam not low beam about a year ago. New switch did not change anything. Checked wires all the way through and could not find anything loose or cut. The earth for the lights seem in tact and well grounded.
My question is does the fact that the plug to the light switch only having three connections with power to them indicate a problem or is that normal? I would have thought other connections would be made/powered when the switch control is pulled or turned?
Am trying to work through these issues one at a time.
I can’t discount the new light switch being a dud.
I also note that when I pulled the plug holding all the lighting cables from the firewall under the bonnet near the brake master cylinder, this disconnected power at the ignition, which may be normal but seemed odd.
I also tried checking power to the headlight plug and got nothing with ignition on.
If anyone can help diagnose this or point in the right direction, it would be much appreciated.
I have included the switch with the terminals that have power going to them.
