Hopefully someone can give me some tips on this: I have a 1982 V50 Special - originally 6V, no battery, no blinkers. I have replaced the original engine with a 12V PK50XL engine and is trying to get the wiring correct. I have original wiring in the scooter, but have changed all the bulbs to 12V.
But, I have problems with horn and brakelight.
Horn: Probably because I still have the old 6V horn? The horn is 'on' all the time, no matter if I push the button or not. Seems strange, because this is a very simple connection - yellow wire with electricity to the switch box (frontlight) - yellow wire from light-switch and black ground.
Brakelight: When I connect the the blue wire for the brakelight to 'plus' - no lights are working until I press the brake - then everything works. And on the opposite: When I disconnect the wire for the brakelight - all the lights works fine (except for the brakelight of course...).
From the PK-engine, I have from the beginning connected black-to-black (ground), the green from the engine to red (stop-button) and the blue (positive) to all the wires from the chassis (via the volt-regulator). Lights and stop-button works fine.
After a lot of trial-and-error - I'm starting to run out of options here - does anyone have any tips on how to solve this?
