worth checking these first before you go buying parts you dont need.
hope this helps

Cheers matey, stuck my tester into the aforementioned plug, I get 12v pos outta one, 4v pos (ish) outta another and nothing (guessing earth) outta the third., but you may be right with the contacts being apart and not making a good enough contact. Will ave a look in the morning. Other than that, me first stop is a new dizzy cap and rotor arm.
Cheers
