This morning my battery was dead I jumped it . While I was running errands the voltage gauge maxed out then went to normal and my Jeep stalled. I had the alternator tested it checked out ok. Any tips on troubleshooting.
Was the battery dead again after it stalled?
Could be voltage regulator malfunctions at random times..
But with the dead battery also..i would check your battery connections and cables, actually take them off, clean everything well, tighten or replace the clamps/wires if needed. Not just look at them.
Sounds like a bad connection and the voltage regulator can't read how much it needs to produce..

On average a 12 volt charging system should put out 13.8 to 14.3 volts (or so I was taught). Battery is generally the culprit. Here is a good tool to own, you will use it forever. A battery should be fully charged before testing. This load tests batteries and can be used to check the charging system output. Three years is not a horrible lifespan for a battery. I have gotten up 9 or 10 years before, but 3-5 is fairly common. Here in the middle east, a battery is on death row after one year. Main reason, no way of know how old it is when you buy it "new".

Yeah... Remove, clean, and replace if needed battery cables and clamps, terminals first.. and have the battery tested since u did the alternator already . Start with free fixes then move on..
A voltage test on a battery is worthless, load testing a charged battery is the way to go.
+1. The only way to confirm dead or dying cells in a sealed battery is to load test it. That spike could be from a cell shooting out internally. On the old batteries that you periodically check the fluid levels on you can check specific gravity of each cell to find out.
Clean the terminals and posts until they are nice and shiny. Every time I have had a pegged volt meter, the terminals were dirty and making a bad connection.
If your rig is parked and stored for long periods of time, maybe you'd benefit from a battery tender?
I use one on my motorcycle when I'm not expecting to be on it for a while. It maintains the battery and keeps it from draining. Unfortunately, I've already found out the hard way (once) that I needed one.
