Greg, I've had the brake light switch fail on my Super. It would only light the lights when the brakes were under extreme pressure, as in while testing them in my garage. They would not light under normal street braking. Once I saw what was going on, I didn't bother with any further diagnostics, I just ordered another switch, which once installed worked fine. I've since talked to other Alfisti with cars of similar vintage with the same problem.

It passes a continuity test when I step on the pedal. I can make the ohm meter go from one to small fractions. It will not, however, carry twelve volts to illuminate the rear lights. I've bypassed the switch and the lights light-up just fine. I've tested the switch several times and it reveals the same symptoms. It breaks resistance, but will not carry voltage. Has anyone ever encountered such a perplexity? modelle 105.04 115.01 -- to be removed from alfa, see http://www.digest.net/bin/digest-subs.cgi or email "unsubscribe alfa" to [email protected] -- to be removed from alfa, see http://www.digest.net/bin/digest-subs.cgi or email "unsubscribe alfa" to [email protected]
