trafficator - semaphores not working

Post by **tortron** » Mon Apr 28, 2008 6:27 am

have tried taking them out and running them straight from the battery - the lights will work, but there is no movement

i separated the coil from the semaphore and tried that connected directly to the battery (with piston inside) and still no movement

i dont seem to be getting any voltage drop across the coil.

anyone got any ideas? are both the coils gone? any other tests i can do to see whats up?

on closer inspection - after cleaning there looks like there are a few small spots where 1 or 2 adjoining wires on the coil have had their surface rubbed off. could this be it?

thats odd the lights don't work on mine until the arm is in the extended position.

i have a sidevalve which has the SF40 trafficators. They dont have the sliding contact like the later ones.

i have decided that the coil was short circuiting, looks like 50 odd years of weather etc has removed the coating of the wire

so i shall get/do it my self - them rewound

lucky for you guys i will document the entire thing and write up a how to
