Possible ?? - bad battery connection caused total shutdown while driving ?

98 Cherokee Sport 4.0

So everything is dead, get a jump, fires right up. Drives about 200 yds, then total shutdown of all electric. Jump again, same results.

Get it towed four miles home and start poking around connections ( as recommended here)- battery terminal is warm, battery has 12 V. I clean the terminal and everything fires right up. So I am good right ????

Here is what worries me ( since this is my kid's daily school driver) - is that all there is? Once the jeep is running, why would a bad battery connection cause everything to die? Once the car is running, is not possible to remove the battery and everything keep going - or is there something in the voltage regulation that will be triggered if there is apparently no battery ?

Thanks

a lose battery connection shouldnt cause that, you can fully remove the battery once the jeep it running, and it will continue to run. if it died while driving it would think could be an alternator problem..

Not having proper voltage to run the engine computer will most certainly cause a shut-down. Jeeps do not tolerate low voltage, bad connections, or poor grounds.

Perform routine maintenance of the start and charge systems. Remove, clean, and firmly reconnect all the wires and cables to the battery,starter, and alternator. Look for corroded or damaged cables or connectors and replace as needed. Copper wires should be copper color, not black or green. Do the same for the grounding wires from the starter to engine block, the ground wires at the coil, and the ground wires from the battery and engine to the Jeep's frame/body. You must remove, wire brush, and clean until shiny the cable/wire ends and whatever they bolt to.

If symptoms persist have the battery Load Tested. Consider that the Crankshaft Position Sensor (CPS) may be in need of routine replacement, as a faulty CPS can cause unexplained stalling.

CJ7-Tim, thanks

The CPS has been replaced within the last three months, and your advice on the cleaning everything is what got me back up and running. What I am leaning towards at this point is that the alternator is on the way out ( it has >150k miles on it) and at low rpms - with no battery connected - is not putting out enough to keep things running, especially at night.

^^ That sounds like an alternator issue. Like said above, with a good charging alternator, the battery can be disconnected while the jeep is running and it should stay running. Have it tested to confirm.

NEVER disconnect the battery while the engine is running on any computerized vehicle. You risk blowing up the engine computer and/or the alternator. Plus, it shows you nothing. A simple $8-10 Volts/Ohms Multi-Meter will do a better and more accurate job of measuring voltage.
