Some background. The truck is a 1950 1/2 ton with a 1954 235 motor. Years ago the electical was converted to 12 volt. the work was done on the cheap and very hodge podge. However, it mostly all works. Headlights, turn signals, after market blinkers, brake lights all work. Oh, dimmer switch also works. Even the dome light. What isn't working are the gauge indicator lamps. Both clusters are dark. I've pulled out the speedometer to have it replaced when I found the bulbs and couldn't get them to light up. I'm thinking the headlight switch might be bad. The switch and the wiring on it all look original - cloth wrapped wires and rust on the terminals. Any thoughts or suggestion on this? anyone seen this problem before? Maybe it just the bulbs. Now that I think of it, I haven't run a test to determine if there is power to the bulb sockets. May try that tomorrow.
Anyhow, any help will be appreciated.
