Went wheeling earlier and everything was fine. Washed off the xj, and lightly sprayed under the hood. Just a quick 30 second spray. Now my dash volt gauge fluctuates between not working at all and 12v. My after market gauge reads between 11.9 and 12.3(digital). Doesnt change even at 60+mph. Havent checked the connections but dont see how and quick spray could knock something loose. Any ideas?

You got water in the altrenator you need to dry it.

How would i go about doing that exactly?? And how the hell would that happen? its under basically everything and I never even shot the sprayer towards it

steam, water and rectifiers do not play well together. it does not take much moisture to ruin an alternator if it's hot! You can try blowing it out with compressed air, but the damage is most likely done.

& boy are they a pain to get out. take the battery tray, fans & shrouds out 1st then you can get it out. also is all metric bolts.

Took the idea and blew out the alternator with my compressor. Nothing looked like it sprayed out of it, but started it up after and it sat at 12.2 for a minute then when i looked at the gauge again it bounced back up to 14.5 and stayed there. Hasnt gone back to 12's all day. I think itll be fine now.
