I have never wired a bike with a Phelon magneto, and it appears that the tail light and brake light are wired hot all the time. Is this correct? On a bike with a Wico magneto, the tail light is switched on the same circuit as the head light.

On my 57 the taillight is hot all the time as is the brake light...my brake light switch is pulled open when running so the contacts points are apart in the switch when I depress the brake pedal the contacts touch and complete the circuit to the taillight hope that helps

Rick , mine is wired same as relic's . Tail light and stop light are wired directly to the tail and the stop switch . So , always hot when running . I took my wiring Que from the M manual and from what I remembered it being when I first bought the bike .

Does anyone know what years did they use the Phelon magnetos?
Was it specific model years or were they just mixed as the demand increased?
-
They used Phelon 1957 and later.
-
I thought the Phelon came in in '56

My 56 has a Wico.

Sounds like a mid year change to me!

My '56 has a Phelon magneto.

I see this thread is a about 4 months old , but ...
Anyway , my '57 is equipped with a Phelon magneto and below is a diagram of how I have my bike wired .
Hope you can make sense of it . :D
Note that I ran a ground wire to front and rear to eliminate the need for any bare frame grounding .

I used what ever wire I had at the time , so there's a lot of black . Fortunately the runs are short and easily traced .

PD, Your drawings are great! And more than make up for your lack of attendance in Portland! All kidding aside they really are great!

Thanks , Tom . :)
Hopefully , I'll see you in Portland , next month .

When wiring that Phalon up, be sure to secure the wires far enough away from the flywheel that the magnets don't rub on them. In the attached photos, you can see where I didn't have the ignition wire secured from moving & the magnets eventually rubbed thru. Those of you who were in Portland 2 years ago saw how frustrated I was when the bike ran great at home, but started only getting partial sparks after arriving. In the other photo, you can see how the issue caused the coil to overheat & the one terminal "popped" loose. I"m going to glue it down & clip off the one spark plug wire.

Hey Mike ,
Good to see you're still kickin' .
Looks like that coil did get a little warm . ;)
My OEM coil came apart in the same place , but for a different reason . Mine was due to some pretty strong cleaning chemicals I used when first cleaning the bike after a 40+ year storage . The casing turned to mush and that was all she wrote .
My magneto backing plate has a clip to hold the wires tight to the back of the plate , held in place by the grounding screw just right of the wire entry hole .
My clip is similar to :

Yes, mine still had the original clip and I had all the rest of the wires under it....why I didn't have that ignition wire under it is anybody's guess....maybe I was just in a hurry....
I got it back together tonight & drained the old gas....tomorrow I'll put fresh gas in it & see if it'll fire up. I can't find the plug wrench I made so didn't pull the plugs yet to check them.....we'll see....

Good luck . ;)

Bad news....no spark after putting the bike back together....I wonder if when that one output terminal blew out it was a signal that the coil is shot? I figure I'm going to drop it off at Wayne's booth when I get to Portland & leave a blank check.....wish me luck....

Mike ,
That coil is very likely internally grounded / shorted . The only way to fix that would be to remove the outer 'shell' , unwind all the wire and coat it . Let that dry and rewind the coil .
I don't think that would be any kind of an easy job as the wire is very fine and has way too many rounds .
Just buy a new coil from Wayne and install it . 5 minutes and you should be on the road again . ;)

Well, the good news is Wayne had a new 2 terminal coil at the meet. I had to shave a little out of the inner insulation to get it to fit onto the laminations. The bad news is that didn't immediately fix the spark issue. With help from "old timers" Ernie & Jim, we got spark (we tried too many things all at the same time to know true root cause, but suspect my points gap was too small), but still no start.....
Ernie started pinching off the needle adjustment on the carb (back when the bike first konked out, I thought it was a carb issue & I piddled with all of the adjustments....so who knows how badly I had it adjusted) & it finally caught & I was able to ride the bike a total of about 2 blocks.....when I returned to the camp, I had to choke it to kill it (we had unhooked the switch to make sure we weren't getting a false ground on the ignition).....when I went to re-start it 5 minutes later, it wouldn't hit a lick......I got so mad, I pushed it over to Sonrisers for the group picture, then pushed it back to camp, and let it set till we loaded it into the truck to bring it home.
I'm sure it will run now as soon as I get the carb tuned in (I'll probably swap back to the new Carpenter carb that I have too).

I have to wonder if Wayne had those 2 terminal coils made or if he found some that were made for a different machine .
