Metal Collar
What is the purpose of the metal collar over the distributor cap of a 1980 VW Scirocco 1.6liter engine?
The metal collar has 3 wires: one from the ignition coil, one from a condensor outside of the distributor, and one is a ground. There is a black rectangular "relay?" attached to the outside of this metal collar where the wires attach. What is this thing? What is it called? What does it do? Thanks
My guess is that it is an external resistor. Supposed to vary the maximum voltage available at the coil during high and low rpms.
