My buddy's car just quit running. It's a 1974 1.8L. He said he only has 1 volt coming from the coil. When he disconnected the yellow wire going from the dual relay to the negative side of the coil the voltage is 12.7. Is this a bad dual relay?

L-Jet uses the neg side of the coil for triggering the fuel injectors. There are some good write-ups on testing the double relay, search for them. (IMG:style_emoticons/default/wink.gif)

Hopefully it was a white/beige wire.
