I work overseas and am at work, but now have something stuck in my brain and nowhere to check it out. Causing a headache...lol.
1 - When flipped to 'dim', does the tail light light?
2- I am having difficulty working out in my mind how the opposing power buss crescents inside of the switch go. So if anyone can offer an explanation that has in fact taken a switch apart...I'd appreciate some commentary.
Seeing the question, I went and tried my lights. Yes, the tail light stays on for both bright and dim. I didn't look inside the switch.
I just repaired a switch for a 26 and the tail light does work on high and dim. Any thing that I don't fully understand runs on magic, without pulling the switch out and apart I would have to say it runs on magic.
I know now that this is apparently running parallel to the Jim Thode/Martin Vowell discussion...
Thanks for the answers guys...
Here is the problem I'm trying to conceptualize shown in photos...remember I do not have a switch in front of me...and that I am only working from drawings on the internet in a cut and paste way.
As I mention on Martin post, I have been labeled certifiable because I bark that 22-27 does NOT use the standard switch arrangement when built for mag only, and that you have to be careful when you take a mag only and 'electrify' it after the fact...
This is the best cut and paste I've come up with but I still can't see how it works contact wise! Nobody will hurt my feelings....show me what I've cut and pasted wrong
George, that's pretty much what I found also when I was trying to figure out how the switch worked. Although I think I would've switched the key to the mag position, just for the aesthetics of it.
George; Power is applied to the crescent that makes contact with the lighting sector of the switch. With the tail light using the center contact between the high and dim, when you shift between the two positions, one of the two contacts on the crescent will always land on the tail light contact resulting in the tail light always getting power. If you watch from the rear as you make the switch, the tail light will blink during the switch over. Now your headache should go away.
On my wife's 1923 Roadster I replaced the switch with one of the new lousy repops several years ago.
I don't remember which is which but the tail light only works on Dim or Bright but not on both.
Probably should find me an original somewhere that works correctly.
Got it all now...thanks
I don't remember how we did it, but my Dad and I installed one of those brake light switches that mount with two screws to the band inspection cover, and made our stock 27 tail light work as a tail and brake (brighter) light. I'm replacing it with a Ford accessory, Hall stoplight
My switch doesn't light the taillight on dim, but it does shut the car off. Luckily, everything works fine (so far) on the bright setting, but I need to work on that switch some day.....
