Hairline crack on back of ignition switch
Found a hairline crack in the bakelite on the back of a 36 ignition switch. Crack is noticeable on the inside but not on the outside. Apparently the two screws that hold the bakelite and the two brass posts in place were tightened too tight. Would this cause some ignition problems I'm having?

Re: Hairline crack on back of ignition switch
Hi Everyone, Here's some more on DK's issue. Sorry but I'll have to stay out of the cracked ignition switch question.

Re: Hairline crack on back of ignition switch
You could test the switch. Bypass it and see if your engine runs better.
That part of the switch with the posts is repopped. And so is the little switch part. The metal enclosure is not. Maybe replacing the switch would be prudent anyway. |

Is there a way you can test the switch while it in the car with a voltmeter? |

" Is there a way you can test the switch while it in the car with a voltmeter?"
I tested mine by measuring the voltage to ground on both sides of the switch with the switch in the on position. There should be no perceptible difference in the voltage readings. If there is then there is resistance across the switch and repair or replacement is needed. In my case I measured 6+ volts on one side and less than 4 volts on the other side. |
