Intermittent electrical problem

So I have a 1997 jeep wrangler with the 4.0L. I am having a serious problem with my jeep because it won't start. I took out my alternator and had it checked at autozone and they said it was bad so I got a new one. My jeep will start sometimes, but other times it won't.

When I put the key in the ignition and turn it to the on position nothing comes on, no dash light, no radio. I have a dim flicker of the hand brake on the dash but hats it. It won't crank, it wonk click, nothing!! But if I sit there for a about 10 minutes and try it it again. It starts right up like nothing was wrong.

Need help please! Where do I start?

Start with the battery terminals and wires to the starter and the grounds. Make sure they are all clean and tight. That will probably solve your problem.

I tightened down the battery terminals nice and tight and the only ground that I know of is on the passenger side of the block right above the starter. Are there any other grounds that I should check? But would loose connections to the starter cause the dash to be intermittent?

Are you familiar with using a volt meter to check for drops? You may be getting excessive resistance in your battery cables causing your starter to not receive enough voltage to turn. It could be as simple as dirty or loose cables, or a bad starter. 9/10 times that's what it's going to be, the other 1/10 is bad cables.

I had this issue for a while too. Did the same things, checked alternator, battery, just had a new starter on so I knew it was fine. Turns out my problem was the connection at the small fuse block right infront of the battery. The smaller 2 gauge wire that comes off your battery goes to a flat copper plate that then feeds power to the fuses and relays, mine was so corroded that sometimes the vibrations of the Jeep would cause momentary power loss, and when I tried to tighten it they broke right off... In the end I just went to the scrap yard and got another used one. But I would defanitely check there. Just make sure if you try to tighten the nut that your not torquing the stud as well and end up with the same issue I had. Hope this helped. Good luck!
