Make sure the plastic housing for your battery has drain holes in the bottom!
We've had lots of heavy rain in our area since we bought our Gulfstream Visa TT a few weeks ago. So last night I went to check on it to see if there were any leaks. Opened the door, flipped the light switch.. nothing. Checked the battery panel inside and nothing. I started to panic-wonder if we had left lights or something on after our last outting. Nope everything was off. Then I'm thinking "geez, did someone steal my battery?" So I went outside and opened the battery housing. The battery was swimming in water. Water was to the top of the black plastic housing. Both terminals were under water
There were no drain holes in the housing! Nada, zip, none. After carefully draining the box I drilled four holes in the lowest point of each corner, put it back together and still no power.
I'm hoping nothing got fried when the battery shorted out. Won't know until I get a new battery. I'm thinking one of those marine type or dry cell (Any ideas?)
Anyway, check the housing, and if needed add drain holes.
