Lost electrical after washing engine

I washed my 2011 Jeep Wangler Unlimited's engine yesterday, drove it home and drove it this morning. Had oil changed and drove home where I preceded to wax it. Had the radio playing after a while the radio died. Went to check and the gages were on but the radio lights were off. Tried to turn the car on but wouldn't even turn. Eventually lost all power including the gages. I removed the battery and started drying the area around the bottom of the battery compartment. When I hooked up the battery, got some power...but not enough to bring up the windows. The fuse box was making clicking noises so I disconnected the battery and decided to let it dry some more. Frustrated and should have known better....but here I am. Does anyone have some thoughts (constructive please) or can give me some guidance??? Thank you in advance...

Charge the battery or get a new battery

Sounds like the battery needs a good charge. Before spending money on a new battery, hook it up to a charger for several hours and let it cycle completely through the charging process.

Unless you took a power washer to your engine it is gonna just be your battery.

Charge it. Batteries need to be maintained. There are caps on top ( unless it's a maintainence free battery, of which they are then throw away). Pop the caps off. Inside you put Demineralized water. ( not tap water or purified water, but demineralized). You can get this in like a milk jug at a grocery store like Safeway ect. Fill the cavities right up. Pop the caps back on. And charge and away you go. ( wash your hands after, it is a batterie after all).

get a volt meter and measure the voltage across battery + and -

if you get 12v the battery should be ok. Just give it a charge.

any less voltage and a cell has gone down. ie .10v

So you drove fine for a while after the wash. Then you went home and waxed it with the radio playing off the battery and it died after a while?

Sounds like you just discharged the battery. Really doesn't take long with the stock battery. it's probably not related to the engine wash although if the water shorted the battery terminals while you washed you may have lost some juice there. And if you didn't drive long afterwards, it may not have fully recharged.

When the battery is discharged it makes a clicking sound when you try to start the engine. That's normal.

Just get a boost and go for a 20 minute drive. See if that fixes it. I bet it will.

Use your plug-in boom box in the garage for tunes while waxing.

Thanks for the feedback; unfortunately, I did use the power washer. I found a small crack next to one of the battery terminals. I'm going to replace the battery and hope that takes care of it.

On the road again...What a relief, the new battery worked. I was concerned that I may have shorten the electrical system. Thank you all for your guidance.
