No electrical power

So I went out to the car last week and tried to crank it but had no power at all. I thought well maybe the battery is bad so today I went out and I checked it. It was a little low but not bad (optima red top). I put it on a charge on a agm charger for an hour. Well now Iím sure itís not the battery since it has juice and the dome light wonít even come on. I checked my fuses and all looked fine. The cables look really good and the connections are great. What else could it be?

Re: No electrical power

Did you check the main splice and the junction block in front of the battery? Check the positive battery connection for crud and possible disconnection?

Re: No electrical power

I checked at the starter it had power and the alternator had power. Fuse box and horn relay had no power Iím going to go and look to find that junction block.

Re: No electrical power

Ok no power at junction block does this mean the block is bad or is there a fuse?

Re: No electrical power

My bad it does have power but barely lights the test light. I donít have the same block that you guys do I have a aftermarket block that has my stereo ran from it.

Re: No electrical power

Ben - The Junction block has no fuses but is fed by a feed wires off the positive battery cable.
Do some tightening and cleaning.
Check the feed wire and the fusible links in the area for damage, disconnects and other issues such as evidence of Mice harvesting the insulation off the wires. They LOVE the taste of the insulation.

Re: No electrical power

Clean the battery terminals and check grounds. You should have almost the exact same reading at the junction block that you have at the positive battery terminal. I serioulsly doubt the junction block would go bad, but the connections definitely could be.

Re: No electrical power

Thanks for yíall help. Yep cleaned the cables took them apart and got some surface crust off the cable clamps. I went through and tightened up the cables at the starter and the alternator. I guess itís good it happened in the driveway. I know itís a rookie mistake but on the outside the clamps still looked new but underneath they were bad.
