thanks for the replies everyone .. I've replaced the wires by soldering in new ones... this time with a little more length which allows a little more play in each wire.
I followed as per Mr Flippant's wiring directions and simply
' removed the chassis, removed the wires from the guide completely, and even removed the front axle assembly. I put the chip in and made sure those wires were arranged to avoid any pinching by the interior, then ran the guide wires up and under the front axle and then to the guide. '
I seriously need more practice soldering, must have taken me a good four to five attempts to get a half decent looking weld.
This seems to have done the trick ... Also, I mentioned earlier it was mainly on a CLC where the flag was hitting hard .. but my mistake it was is fact a XLC but occasionally also on one of the CLC
On a lighter note... I've just returned from Hobby Co. They're clearing out their Scalextric Digital gear... less than half price !! I bought a few CLCs . they're selling the C1223 Triple Cup for less than 130 pound ! NICE deal if you live anywhere close to a store.
