Sounds to me like your KV's are to high; thus it is burning your HT leads away as the sparking voltage is to high.
Fit a new cap (make sure you get a geniue BOSCH cap, as the cheap ones can't handle the Sparking voltage, so I am told by my BOSCH Supplier), rotor and leads; also check your spark plug gaps are correct.
Make sure that your leads are tight fitting into the cap, adjust the brass bit of the leads to make it a good fit if need be.
(Typical kv voltage is 10,000 volts but 0 amps thats why it just gives us a jolt and doesn't kill us.)
If this is helpful to you
PLEASE rate me.
