Expert Posts: 2264 Location: McComb, Mississippi | About to begin the work on the auto dimmer. Has anyone here diagnosed these or found a place to source parts such as the photocell? I have a new vacuum tube for it. Thanks for any help. | ||

Just bench connect it and put the beamer in a household paper tube so you can obscure the beamer and let in light. You just need a foot dimmer switch, a power source (car battery), a sealed beam headlight and some wires. | ||

The entire unit appears to be dead. Just trying to troubleshoot. | ||

Board Moderator & Exner Expert 10K+ Posts: 13042 Location: Southern Sweden - Sturkö island | Does the tube lights up? There shall be an orange glow in the tube. If so, there is also a warm-up time before it will go into function mode. The photocell must be obscured so that you know that high beam is allowed. expose the photocell to light and the unit should dip the beam. | ||

Yes, the tube does indeed light up.. the electromagnet contact pulls down but does not open when you try to manually override the system by using the floor dimmer. | ||

Since I have I found that the capacitors are bad oh, do you recommend standard replacements or would you recommend capacitors with different values to compensate with halogen and LED lights? Thank you for any help | ||
