Its doesn't  give a spark but i change condencer and module coil its still working fine what can i do please help

I haven't seen inside a 3Y dizzy, but does it have two modules inside like a 5K??

The electronic ones I have seen have no condensor, just a pickup module and an igniter module.

It appears there were quite a few different types of dizzy for the 3Y, with both points & electronic.

The ones for South Africa, were apparently different, & that is where Sipho is located.

As Sipho has replaced the condensor, we have to assume it is a points type, which were fitted mainly to the 3Y engines, according to this blog at the above link.

Maybe Sipho, your issue is with the rotor or the spring & carbon rubbing point in the top of the dizzy cap.

Would need a bit more info, to solve this one. At least if it is points, it is the cheapest & easiest to fix.
