Customer Question

When I reconnect my battery cable to the post just my headlights and taillights come on. The rest of my electrical system is dead. I keep the battery disconnected because I don't drive the car that often

Hi, welcome to Just Answer. I’m Ron and I’ll be helping you
today.
Before we get started though, Please understand that I don't know
your skill level or tools you have to assist us. Also understand that
I can't see, smell, hear, or touch the vehicle either, so patience is
appreciated. JA is a great Q/A site, but it does NOT replace a
repair shop.
My goal is to make you happy and get a great rating in return for
my time. Sometimes I have to give you bad news that I know you
didn’t want to hear, so please don’t shoot the messenger.

You need to check power to and from the power distribution box under the hood for breaks or corrosion. Check also for any blown fuses.

Thanks, Ron

where is the power distribution box at
Expert:  rpmdiag replied 5 months ago.

Under the hood near the battery unless your battery is in the trunk or under the back seat.

Thanks again and please remember to rate me 5 stars and keep this link in case you need me again later on.

A 140 amp fuse is blown. How do I grab it
Expert:  rpmdiag replied 5 months ago.

It may have a hold down screw in the center of it or it's bolted in from the bottom. Those don't just blow for no reason either, something must have gone wrong at some point like maybe crossing the battery cables.

Thanks again, Ron

there isn't a screw in the center but to the left side of another fuse is a nut if I loosen that will I then get to the bottom?
Expert:  rpmdiag replied 5 months ago.

Try that, I don't have any way to see it from here and they're not all the same.

Well that didn't do it. any other ideas how to get it out
Expert:  rpmdiag replied 5 months ago.

I'm trying to help you and already have gotten you to this point. Please understand that I can't see that from here. I hope this doesn't affect my rating at all. Can you upload a pic for me to see? You probably need to remove the whole box.
