Hi Everyone and Happy Holidays,
Our 1992 Dodge Shadow left us on the side of the road the other night. We decided to do some back yard checks on the ignition system. Using a computer probe (like the ones sold at auto parts stores), we checked the primary connector to the coil. We connected the probe as directed (Red clip to the positive battery post and Black clip to the negative battery post), then disconnected the primary connector to the coil.
These were the results as we cranked the engine:
1) While touching the probe tip to the terminal to the Grey wire: the Green light and the Red light alternately flashed (I am thinking this is the signal from the computer).
2) While touching the probe tip to the terminal to the Green wire with an Orange stripe: the Red light glowed.
3) Then using a regular old test light, to jump the Grey wire to the Green wire with an Orange stripe: the test light flashed.
It seems to me that this type of testing was talked about on the site a long time ago, but I can’t find the discussion now. I am hoping that someone can let me know if these results are correct.
Thanks for everything
