Dead battery kicks inertia switch?

Hi,

I'm new to the forum. I signed up because I had a problem a week ago with my Ranger.
I have a 05 Ranger xlt 4x4 v6 4.0L. Reading through this site helped me solve my problem, but even though everything is working fine, I still have a question.

My issue started when I was driving dow the highway. The engine cut out on me and I had to coast to the shoulder. My battery was completly dead and wouldn't hold a charge. After reading this site I found out about the reset button to the fuel pump. Once I pushed that reset and jumped the battery, my truck fired right up and I could drive around fine.

I tested my alternator while the truck was running and I was getting the usual 14V. So I got a new battery (duralast gold) and everythings worked fine since. Here's my question; Would my battery dying (it was 7 year old OEM battery) somehow have kicked the inertia switch which caused the fuel pump to shut off which caused my truck to cut out?


(on a side note -- I did not hit any bumps that would have caused the reset button to "go out")

Thanks for you input

The inertia switch is mechanical. They also pop sometimes for no reason or if they are kicked.
That this happened at the same time as the battery failing I would chalk it up to coincidence.
If the switch pops again,look to replacing it.

That's the same thing my brother in law was thinking. Since no fuses were blown (which I can't see how a dead battery would cause a blown fuse) he thought it was a coincidence as well.
Thanks for the reply; that makes it 2 for 2 saying it's a coincidence.

Had my inertia switch go bad with about 3000 miles on the odometer, and had it replaced by the dealer under warranty. Didn't hit any hard bumps or anything, just said it was a bad part installed at the factory.

I'd say they are unrelated as well so your 3 for 3 and majority rules lol
