Re: Ignition '69 Merc 1250 Tried Suggest. No Luck
Well, allrigty then....<br />It's time to get funky and technical on it!<br />Turn the key in the "run" position, and see if you have 12volts between negative and the white wire at the switch. It will be on the 'F" terminal of the ignition switch. If 12VDC is missing, disconnect the battery.<br />Set the meter to the ohms scale ,and check for continuity between "A" and "F" on the back of the ignition switch when it is in "ON", and no continuity in "OFF".<br />If not, replace the ignition switch, if you do, and you had 12 volts , then the switchbox may be bad, but not likely.They ]do fail, but it's more likely,a bad connection. Look for corrosion at all the terminals ,especially the white wire from "F".
