1966 Suzuki B100p Turn Lights How do you connect??

[marty tilley]

I almost have my 1966 b100p restored and working. I replaced the carb with a new one, a new rubber air intake going out of the carb to the air filter, a new feul petcock and a new battery. I would like to get the bike on the road and have been told it does not require signal lights. I would like them for safety purpose and have suzuki lolipop lights to mount to it along with a turn switch. I tested the switch and it will work but they will not blink. I take it I will need some type of relay. The switch has a Blue and green wire for left/right and a white for ground. The turn lights has one yellow wire and the body is ground. Can someone talk me though what I will need to get this working. Perhaps you have connected something similar for a b100p or other bike. If you have example of a relay flasher I will need and how to connect it would be appreciated. Thanks.

yup you do. This seems to be a good fit https://www.ebay.co.uk/itm/SUZUKI-GENUINE-NIPPON-DENSO-6V-FLASHER-RELAY-/400571281020?pt=UK_Motorcycle_Parts_13&hash=item5d43e8ae7c I'm guessing it is 6 volt?

Wire from switch to relay, then to each pair of lights

On a bike that old it's very possible that it typically had a 2-wire relay wired like this:

Battery - switch - fuse - relay - switch - lamps - ground.

Power from the battery through the ignition switch to the fuse, through the relay, into the centre pole of the indicator switch which is always live when the ignition's on. Moving the switch left or right sends power to the left (or right) indicators which causes power to be drawn through the flasher relay. The lamps might be 1-wire or 2-wire type. If they are 1-wire then they ground through the stem into the frame. 2-wire are more reliable as they return directly into the loom.

The relay is probably a bi-metallic strip type. When the bulbs are on power is drawn through the strip which heats up and bends, the contact opens and the bulbs go out causing the strip to cool and straighten until the contacts close, lighting the bulbs and repeating the flash cycle until you cancel the flashers at the switch.

Here's an example of a typical schematic:

Of course, if all you have is the switch and indicators were never fitted then you can wire them up as you see fit.
