'96 Cherokee here and right now I'm dealing with a no start after a few weeks of suspicious symptoms. She's been driven a lot less over the past year and about a month ago she began starting a little slow. I've got an oversized battery in there so usually she cranks right up no problem. I started monitoring batt voltage and saw around 12.04 V with engine off and 14.10 V or so running. Right before I get the new battery I head to Advance and they run a battery/alternator test. Kid tells me my batt is bad but alternator is still good.

So I lay out the $ and install the same size 34N EverStart Maxx 800 cca from Wally's and the slow start persists. Measuring the new battery with engine off yields consistent readings of just under 12.7 V, so for the past few weeks I began charging the batt at 2A which seemed to help. A few days ago I venture out for an errand and the engine doesn't restart to get me back home. I get no clicks or cranking at all with a key turn. Batt measures 12.67 V at the terminals. Dash gauges seem to react with the key on, voltmeter reading ~11.5 V, although I'm not sure how accurate that is. Fuel pump pressurizes.

Something that happened right after battery change out, which may or may not help in diagnosing the problem, is that my pass side headlight only illuminated half way while the driver side stayed full bright. I have an LMC Truck aftermarket headlight wiring harness giving 55/100w low high beam. It's the kind where you run the lights straight off the battery through additional relays. Had to tinker with the light harness a bit to get the new batt in and may have compromised a connection? Maybe a ground? Either way the pass headlight started showing full bright after only 1 or 2 occurrences and has been right ever since. With my alternator testing good and a new battery I wondered if maybe a loose connection was draining my voltage. I was in the middle of testing batt V connected vs. disconnected over time but this no start happened before I could get it done.

Last thing to mention is that recently I've been removing both my fuel pump and starter relays for security reasons. The way it's acting now is exactly like when trying to start with both relays removed. Being that the fuel pump is pressurizing should I consider testing the starter relay? Other than that could I have caused some kind of part failure by removing and reinstalling the relays maybe around 5-6 times over the last month?

All ears

A loose connection will not drain voltage. What happened with the headlight was probably a bad ground or loose ground wire. It sounds like your battery is strong enough, but you have too much resistance in the starter circuit probably due to a loose ground wire or cable connection or corrosion under the connection causing too much resistance in the starting circuit. It could be a loose connection or broken wire going to the starter on the positive side as well. If you have jumper cables and another vehicle you can connect directly battery to battery to see if that makes any difference. It probably won’t. Then move the ground on the Jeep to a good ground spot on the engine. If it reacts favorably to that, it’s the ground cable connection from the battery causing the issue. If you know it was a good ground spot and it doesn’t get better you either have a bad connection or wire on the positive side or trigger wire to the starter or your starter is starting to go south.

Thanks for the advice wagonman. Based on your and other advice I'll probably just go ahead and replace both my batt cables as they're 24 yrs old, and then check all connections leading to the starter. If all connections look good I'll bridge to the starter selenoid w/ some jumper cables and see if the starter turns.

Turns out I've got a problem starter. Cleaned both batt terminals and engine ground and got nothing. Tapped the starter a few times and it fired right up. I'm getting advice it's probably my starter solenoid and that I should just replace that at about 1/4 the cost of the whole starter. I've always heard when starter motors get old their elec connections wear and tapping is what remakes the connection again. I've never heard of just the solenoid going bad so I'm not sure what to think. Should I do the just the solenoid or the whole starter w/ a lifetime warranty?

If tapping or banging on it causes it to work, that is usually a bad spot on the armature. The banging causes the armature to move and work again. Be careful with the lifetime warranty starters. They usually only replace the broken parts and not the worn ones. I’ve bought them before and usually I was replacing the starter almost monthly. I went to a local reputable rebuilder and never had a problem again.
