no spark

[MColes]

just fitted the new engine, not getting a spark at the points

which way around do the wires go on the dizzy?

[Matt]

From memory there is a plain white wire that goes to the + side of the coil (- if you still have posative earth) then there is a white wire with a black trace that connects to the other side of the coil, and another white wire with a black trace that goes to the body of the dizzy.

I wasnt getting a spark from a dizzy that hadnt been used for some time, I ran some wet and dry through the points to remove the build up of corrosion and all was well

[MColes]

nope still no spark. any other ideas ?

[Matt]

well what have you done to it since it was last sparking?

[MColes]

Well there is a spark at the terminal into the dizzy and the wire from the terminal into the dizzy and the wire from the condenser appear to be connected correctly to the points. But still no spark at the points?

[aupickup]

have you put the points in correctly

[Matt]

the dizzy works by by making and breaking an earth, if the side of the points that move are constantly earthed you wont get a spark. There should be an insulating sleeve that goes between the loop on the back of the points and the pillar with the bolt, its top hat shaped. The wire from the condensor is then bolted on to this, but rests on the rim of the hat so it doesnt touch the points...

does that make any sense?

the other thing to do is to get a 12v bulb and attach some wires. Attach one end to the posative side of the batt and the other terminal to the one on the side of the dizzy. when you turn the engine over the bulb should flash on and off

[MColes]

it all looks just as you described. No bulb to test it.

still no spark

[MColes]

Sorted now.

Thanks all
