Thread: 3.9 V8 DISCO GURU NEEDED IN FRESHWATER, 2096

Sounds like the usual ignition module - if still on the side of the dissy definitely replace (earlier models)and if a later model it will be remote form the dissy (near the coil I think) and may be worth while replacing as well.

What Garry said. But also check all plugs and connections before sending her away. It sounds like something fairly simple, but just has to be found.....
For the sake of maybe an hour, have a look around for a loose connector or dirty connections.
Check ALL earths. Including the mounting point for the coil and its associated wiring.

Well, followed Bee_utys modification instructions, got the BIM024 in (Pic attached), took out the dizzy to remove the ignition module, was easier than breaking my fingers!, and finally have a resemblance of a spark!, not enough yet but something, see video clip attached.

In the third pic there is a shot of the dizzy, does the spade on the left nest to the blue plug need to be attached somewhere?

Thanks!

The spade lug is for an earth connection, you could use it to connect a shield around the pickup to module wiring, either coaxial cable or make a foil shield under an outer wrap but I don't normally bother. Just keep the pickup wires away from the alternator or the other wiring to prevent it from picking up interference. I often just tie this wiring to the top radiator hose.

On the subject of spark strength, I hope you are using a suitable electronic coil with a low resistance primary, not just some generic points coil. Also the type of plug leads is important, a spiral wire (inductive core) type will give the best spark energy transfer.
