Box of Sparks required

jimmy · 11-08-2011, 01:14 PM

Looking for some help folks.
My sons 1992 SR125 was running well until a few days ago, it then started struggling under load. I replaced the plug, cap and HT Lead but was still met with a very weak / intermittant spark. Soon even this weakened spark was lost. I'm not much good with one, but tried a multimeter across the terminals and between wires and the continuity appears fine. I cleaned all the connections and multi plugs. All to no avail.

Anyway the new coil arrived today. First thing was it only had one wiring terminal whilst the one I removed had 2 terminals with the red/white wire connected to one and the orange wire connected to the other.
How would I wire the new coil.

Having now replaced all components from plug to coil, what else should I be considering

Spoke with a local mechanic who assures me it is the CDI thats the problem, so I will sent the wrong coils back and try to pick up a Black Box
