my first job will be to check them out to see what they read......if Not good they do take returns so that's good........ but like you say 5.0 is better that's what them at Common Motors say to use.

It depends ... ignitions with capacitive discharge CDi use coils that are typically less than 2 OHms ... really depends on the type of electronic ignition,
mo goldie:
Yes well as I say them over the water say 5.0 with their`s ...... but where do you go ?
K2-K6:
Worth an overview of wiring to electronic unit to discuss ?
Ordinarily you'd have power to unit switched by ignition, earth competency to allow the coils to switch, trigger wire to sensors to control that switching (to earth) that goes to unit to toggle switching in time with cam etc. Power to coils and their earth routed to the unit to be switched up and down by the circuit control within that.
Is there wiring diagram with unit ?
mo goldie:
Hi K2
here is a link to the insulation of the shockwave and a video too.

My starting point would be the black earth cables on the mounting bracket. The one in the video has little chance of earthing as the frames paint is still on. Make up another wire from the same bolt and take it to the earth either on the loom or a good reliable earth on the frame somewhere. Suspect those dodgy red cable connectors as well.
