Re: Voltage at Coil Positive by Sam Watson
Post New Message Joe, if I may, how about using a jumper cable between the engine and the battery negative post to see if that eliminates shock? Also, I'd suggest the following. With the key "off", disconnect the wiring plug from the control module by backing off the screw in the center of plug and removing plug from module. Measure voltage across battery terminals. Turn key to "run", measure voltage between coil+ and engine block, voltage should be no less than 1 volt below battery voltage.Next check voltage at coil -, on either terminal of coil you should read battery voltage or a max of 1 volt less. If it's more than 1 volt lower than battery voltage then you have a fault in your circuits. Start checking by reading voltage between engine block and battery plus, in all the checks, maximum allowed voltage loss below battery voltage is 1 volt. Next check between battery + and surface of control module---scrape a little paint if need be. Come back with what you find.
