I pulled the dizzy and brought it inside to my desk for a check with the digital multimeter.

With manual counter-clockwise rotation and a digital meter set to the 200 ohms range, the center pin to the "left" pin (the one closer to the condenser) returns 0.6-0.7 ohms before continuity is lost. The center pin to the "right" pin (the one closer to the vacuum mechanism) returns 1.0-1.1 ohms before contact is lost. I get that normal "alternating" 360 degree reading as described in the VClassics article on Druck-Jet.

I'm a little bothered that the resistance for the left set is about half of the right set, but unless you guys suggest otherwise, I'm not going to mess with bending the contacts for a measly 0.4 ohms. That may adjust out if I loosen the screws and wiggle a bit.

Clearly they are "breaking" so I'm at a loss to explain why my injectors are no longer firing.

The Fault tracing manual does not seems to suggest much here aside from "Replace Injectors"
