Time to clean the dust etc from the coil tower and HT boot. Damp time of the year can cause this on start up if the car is used and not a garage Queen!  | ||

A dab of silicon grease on the inside of the king lead boot might help too. | ||

Dampness also provides a path for ignition wires that should be long replaced to short. Make sure they grease is for electrical work, otherwise it does not conduct. | ||

I would be concerned by those crimp connectors too. ( one of my pet hates ) I would replace them with soldered brass with sleeves. Mark | ||

Preinsulated crimps should never ever be used in any carb boat truck or motorcycle . However an uninsulated crimp ( as invented by the Japanese wiring suppliers ) that pierces the insulation is by far better than any soldered terminal better still if a 1/2" of glued heat shrink is shrunk over the actual crimp before the insulating sleeve is pulled down over the terminal | ||

The only reason why the terminals are crimped in the first place is because it is easy and many can be crimped per hour. It is not as good as a soldered connection with a shrink sleeve around it. | ||

Depends what you mean by good, where the wire is & what it is doing Soldering makes the end of the wire solid and prevents the individual strands from bending & twisting This creates a stress concentration point where the wire will work harden & fail unless it is very well secured which rarely happens. So on that coil for instance the wire should do a loop back down the body of the coil & be clamped tightly to the coil | ||

For the record . Running LPG causes the coil ht output 7-8000 volts higher than petrol. (the Shadow 2 has had the opus ignition fail in the past, could the coil HT put a strain on the electronics?) Good news, coil tower insulation was ok. Main prob was the coil king lead rubber boot being perished allowing the intermittent arcing from the coil HT to the LT coil male spade terminal when damp conditions prevail. IMO the NGK indium plugs also put a higher voltage on the system as more voltage is needed to fire the plugs due to the makeup material of the electrodes. LT wires and the resister HT leads do not need soldering. Ripaults genuine crimped connectors never had any probs. Scotch locks gave up using them years ago.    |
