1967 R60/2

I finally completed my Hella turn signal instal. The BMW 6V 3 prong flasher that came with the kit did not work when tested. So .... I went to the local auto parts store and picked up a universal 2 prong flasher that worked great on the bike in the garage. When I rode the bike however ..... the flashers were erratic. They were fast, slow and sometime intermittent.

Question is ..... whats the difference between a 2 and 3 prong flasher and which one should I use on the /2? Maybe I should have tried the BMW flasher on a ride. I just assumed if it didn't work in the garage it would not work on a ride.

I tried grounding the system from the battery to the handlebars, no success.

The trick is to insure that

The trick is to insure that you have a 6 vdc flasher. (Available on Amazon for a few bucks!).

3 terminal ver 2 terminal flasher

The 3rd terminal is used for the the indicator light on a cars dashboard and not used in your application
I am using it as I put a green led in my headlight bucket to remind me that the flasher is on

I am using a 550 3 terminal flasher for my 12 volt system
535 3 terminal flasher relay for my 6 volt system
Can be purchased at any auto parts store

P terminal to indicator light (if used)
X terminal power in
L terminal to load (center of flasher switch)

PS
You must add a load resistor if you are using led lights on your bar ends

Blue light is for my high beam indicator

Please don't shoot me because the bucket lights are not original
Easy to redo

Flasher

Ok, the BMW flasher was 6v. It must have been a bad flasher. At $22 that sucks.

Tommy .....
I'm not running LEDs in the signals so no need for a resistor yet. The 535 came up in my search but that's not the one I got. I'll try that one tomorrow. NAPA has them for $9. Now that I know what the 3rd post is for I may run a small indicator light somewhere through the headlight shell.

Just so I'm getting it right ..... (I have the chrome up/down toggle/horn switch) .... Down is right signal? Up is left signal?

Turn signal switch

I wired mine up or clockwise right signal
down or counterclockwise left signal
Button in for horn or kill

I think your flasher could be ok
If you have a bad connection it could act like you said ok standing still and erratic while running
Cheap enough to try the 535 and if that doesnt work you will have a spare flasher

Good luck

Tommy

Flasher

I ended up with the 535. All is well. Its installed and it works going down the road just like its supposed to do. I attached the flasher to the right wire bundle holder so it won't flop around inside the headlight bucket. I really like the new look.

Sorry for the sideways photos. Grrrrrrr

Chrome Was

The chrome right switch was the first iteration of the turn signal switch. You have to use it if you have the rounded perch, along with an adaptor piece. The later perches with the flat already machined accept either type of switch.

Dave is correct. I had to drill and tap the round perch to mount the adaptor. I also had to tap the adaptor to be able to secure the chrome switch.

The Hella bar end signals completed the frame up restoration of my /2. Now it's time to ride and move on to my next project. There may be a new (old) bike in my garage next week.

Bracket for flasher relay

Can't start your new project until you mount the flasher relay

You are correct. Thanks for the idea. I have several of those clamps in my parts box.
