Truck will not start.

Is this a test an auto parts store can run to avoid charges?

If there's a counter person there that was a mechanic maybe, but not likely have the equip or time to do the test. Usually install meter to battery cable and read the amp draw, then determen what circuit, or plural, it is coming from. You could ask them but ?????

Advance Auto and others will run a check on the electrical system for free. That is how I checked the battery and alternator. I just was wondering if a place like that would have the ability to perform the test mentioned.

Ask and see if. They will usually check to see if you need a battery or alternator, but this test is completely different. Never hurts to ask

Thanks!
