Changing the interrupter switch

Hi Miguel,

I assume you are referring to the park neutral switch. This is located close to the oil pan on auto transmissions. It is as simple as unplugging it and removing it. Once you locate it, you should not have to remove anything to change it.

Here is a drawing of the location.

More than likely that clicking is the starter solenoid. If it does start it could as simple as a dead battery. If not then I would think it is a starter. The way to tell is to measure voltage at the starter while cranking. If you have battery voltage and it doesn’t turn over then I think it’s the starter.

So when you say he starts it from under the hood by jumping the starter, then yes. I agree sounds like an ignition switch.
