For the first time on my 1990 burmby I pulled the dist cap and found a little 'black box' in there instead of the old contact breaker and has the two wires from the coil conected to it. The 'black box' doesnot have any contact with disty shaft and vacum advance rotates the plate the 'black box' is mounted on.

 

Is this an electronic dizzy?

Do i need a special cap and rotor for it?

Yes, that is magnetic pickup loop. As one of the magnets on the shaft rotates by, a pulse is generated in the pickup loop and the signal is sent to the ECU so it can send a pulse to fire a plug.

 

Some models had a couple different disty makes so it would be good to know what make your disty is. There have been mixups with the cap and rotors.

Has yellow and black wires running to dist.
