Hey, I have a question about some wiring on a 71 clubman with a 998cc.
Theres a wire coming from the Distributor, does this go to the coil and if so is it the +ve or -ve?
How many wires go to the coil?
We have the one from the distributor, a green wire and a white wire.
Any help would be great even some pictures if anyone has them.

Thanks
Blake

Assuming the car is Negative earth,

The wire coming from the distributor goes to the -ve terminal of the coil (this is the trigger wire and causes the coil to produce a spark when the points break).

The white wire should be the 12v supply (check with multimeter) - this goes to the positive on the coil.

I'm not sure about the green wire (can't find it on the wiring diagram), but does your car have a tachometer/rev counter? If so that's probably the sensor wire - not 100% but I think that also goes to the -ve terminal on the coil (but this depends on the tach itself).

Oh ok thanks, we gave it a try.

Am i suppose to get a spark inside the distributor when we turn it over with the cap off?

Not sure what you mean, there should be a small (hardly even noticable) spark at the points when they open. The lead that goes from the coil to the distributor should send out a spark each time the points open - you can test this by removing the lead from the distributor, peeling back the rubber boot and holding the end of the lead about 1mm from a metal part of the engine (don't touch the end of the lead with your fingers or you will get a jolt!) - when you crank the engine you should see sparks between the lead and the engine. If you're not getting a spark, the coil, leads, points or condenser may be faulty.
