S130 Electrical issue

[t28c34]

Blew an attachment hydraulic line that sprayed me and part of the cab with oil. I power washed the outside as well as the engine compartment while I was at it. I lightly sprayed the oil off the inside of the windows without hitting the upper panels. I let it drip dry a few hours , then started it up and put it away. That was a week ago.
Today I went to went to use it since the, this is what I got…
Turned key on, lights flashed randomly. Tried several times with the same results with just a short buzz from the buzzer

I tried one more time and got nothing at all, no light, buzzer, nothing.

Checked front and side panels for anything obvious. Nothing found

Checked engine compartment, nothing obvious.

Battery voltage was 12.65 volts. Same voltage at starter and on each side of the mega fuse. Tried jumping the starter at the solenoid and only get fine little sparks.

Checked and found 12.65 volts at the starter switch. Checked all fuses and found to be ok

Tried turning on switch and switch power solenoid buzzed. Recycled switch and got normal power up. Gauges where they should be, seat belt light on and hour meter showing time on it. but no start. Switch power continued to buzz. Turned the switch to start and everything went out.

Tried again, put the lap bar down, just all lights on, buzzer on then everything off and hear solenoid click off under the seat. With lap bar up, no clicking under the seat.

Checked the switch power solenoid socket. Get 12.31 volts on 1 and 5 sockets. Tried swapping solenoids around and get the same results.
Any ideas? Did the main controller get wet somehow and I'm screwed? I've pressure washed the engine compartment in the past with no problem.

I am kinda leaning to the starter, if you jumped it correctly and all you got was sparks, something is wrong it should have turned over. get another person someone in the cab with all the saftys in place and try that again. It should go, if you have a meter or test light go on the starter lug from the start switch wiring to make sure when you have the key in the start position you get power to the solenoid on the starter.

I would start by cleaning and tightening your battery terminals and all grounding connections. You would be amazed at what this will fix.

Another possibility is that you got water into one or more of the wire connections. The main connector, just above the battery, is connected directly to the controller. It is where a tech will connect the computer to diagnose and calibrate a machine (it is also where the auxiliary electronics control wire attaches). Make sure to dry and clean this using something like WD-40 Specialist Contact Cleaner Spray. If that doesn't fix the problem clean and dry any other connections that you may have gotten wet. Water can migrate down the wire loom until it gets to the connectors causing it too short, so keep that in mind as you are looking at the wire looms.

I pulled the starter and did a few bench checks to it. solenoid works, motor doesn't. So, I'll track one down.

Back to square one. Installed a new starter and get nothing. No lights, beeping nothing. Tried jumping the starter and nothing there. Just a few little sparks.

sounds like a bad ground, if it got wet and it was so so to begin with I would check and clean all grounds, did you bench test starter prior to installing it

I know your voltage looked good enough, but just so we can check the box off maybe you should load test the battery and see if that could be some of the problem.
