Diesel Side by Side Club Car dead after washing!
 

Brand new to this forum and new to side by sides/carts. Hope someone may have some advice.
I might give too much info but here it goes.
I just bought a 2018 Diesel Club Car Carryall 1700. It has 780 hours on it. It was cranking and running fine when I got it. Friday I decided to wash some of the caked up mud and dirt off. sprayed under body, engine compartment and radiator area under hood. Tried to keep water off electrical as much as possible. Temps here got down below freezing Saturday night and when I went out yesterday, it would not crank. It wont do anything! Turn the key and nothing. Battery is charged (12.8 Volts). I was going to spray de-greaser on the engine so the last time it was running I cranked it while spraying the engine compartment and then shut it off after about 10 minutes just to get warm for the de-greaser (which I didn't do). Any ideas on where I need to start?
