Subject: Re: Car broke down.... by Woodstock on 2010/10/18 22:27:41 We just have had the ???-signs in our eyes last week, after chasing down a no spark symptom for a full day! We changed all ignition parts from left to right. Turned out to be the wiring to the instrument panel, in particular the tach signal. We just had to unplug the tach connector at the distributor and felt like real idiots, when it fired right up. We came close when I measured the voltage at the distributor with the cap off. The middle is of course ground, the other two terminals left and right need to have full 12V battery voltage. Ours had 10.7V on the "bat" side and 4.2V on the "tach" side. Did you try already to start it with the EST unplugged? |
