Jeep shut off and died in a shallow puddle???

1985 jeep cj7 258

I was messing around in a water hole last night (water barely reached my hubcap) and I was in 4 low just playing around spinnin all four tires and all of a sudden my jeep just shut off and when I turn the key my lights and everything still come on but when I go to crank it all it does is Dim my headlights & doesn't even try to start all it does is make a single click sound somewhere by the motor when I turn the key to start position .

Im still learning my way around how stuff works but I'm thinking water in my distributor? but it looked bone dry.
Also Air filter seemed dry

Any ideas anyone?

The headlights dimming when trying to start it is a sign of low voltage in the battery.
The clicking is the solonoid doing it's thing, but not enough power to turn the starter.
If the distributer was wet, it would crank , but not start.

Have the battery tested, and go from there. Start at the beginning, as my dad always said.

In a case like this it's plausible that the alternator quit supplying power to the battery. I'm assuming the engine cranked over strong at the beginning of your adventure, so that rules out dirty cable connections.

Driving around on battery power at night only works for a short while until the ignition system and lights drains the juice left in the battery down far enough to kill the engine.

Of course it had to wait until you were in a puddle to cut off the engine. That sounds just right

After you get your battery charged up just put a volt meter on it with the engine running. Should be registering somewhere around 14 volts and will slowly drop down to 13.5 as the battery is topped off after cranking it up. If it's 12.5 volts with engine running then the alternator is not supplying power.

I had that problem. Turns out that my Motorola alternator was worn out, probly had bad insulation , and killed the engine when water got in it..

I would be checking the connections on the main battery cables first. The bumping around might have knocked one loose or a dirty connection decided the water was the last straw and quit. Don't forget the cables have two ends...
