SEMAPHORE WIRE AND BULB

Post by **flying** » Mon Nov 27, 2006 8:39 pm

ive started to look at the traffic indicators on the moggy and found they have stuck closed...so far got one unstuck and its moving if i put power to it but not getting a light......does the wire heat up to produce the light when is fully up and its touching the contact point on the side, or does the wires fail after a while etc ? any ideas how

As far as I know the trafficators have only got one wire to turn the power on, which makes them swing out. As soon as the power is turned off, it should return.

they take a festoon bulb, which is put at the end of the orange bit, with the end touching the metal strip holding the actual plastic in.

I will try and make some pictures if this is not all clear enough

Yes. The trafficator doesn't work with out the metal strip.

they take a 3W festoon bulb (Lucas No. 256 12V 3W)

Hope this helps a bit.

Don't put weights on them. Otherwise they won't come up

Really depends on the weather wether they come up or not

Make sure that the metal bar that goes down inside the electrical coil to make a 'solenoid' is free to slide - WD40 will usually help here.

You should NOT be able to just lift the arm out - there is an interlock that is released when the power is applied to make it work. The interlock prevents the arm jiggling about when it is supposed to be down. You should be able to see it and release it manually, but be careful!

One wire only. When power is applied the arm comes up and towards the top of the movement there is a switch that makes contact and illuminates the bulb (if fitted and working!)
