Q: How can I tell if I have a bad neutral safety switch?

asked by on

I have this 2002 Ford Explorer that has way over 200,000 miles on it. I drove it to the hardware store went in for about five minutes got back in and turn the key and nothing. The lights, horn, wiper, dash, and dome lights works fine. So I had to call AAA and get them to pick it up then the first thing i done was get my vote meters and check the battery and it was 11.7 so I figure that was about right because I was checking the lights and stuff then I went to the positive cable at the starter and had power there then I checked the small wire that went to the starter and had my son turn the key but there was no power so i took the starter off and bench tested it and it woke right up so I said it must be the neutral safety switch. So my question is how do you test the switch. This vehicle is a spare that I keep just in case we need it and it gets about 500 miles a year on it.

My car has 20000 miles.
My car has an automatic transmission.

Hello, thanks for writing in. The switch should show "connectivity" (zero resistance) in the "Neutral" position for a successful start. Keep in mind that these symptoms could also be from the ignition switch. If you need help having this issue checked, a certified pro from YourMechanic can come to your car’s location to pinpoint the cause of the no-start and replace the neutral safety switch if necessary.
