All you have to do to clean connections to TCI is pull battery and box. Its right under battery box towards the front. If you are fair with tools the TCI can then be removed by going up from the sides (removing side covers) under it with flex shafts or joints. You will figure this part out as you look at it, but you can clean connections after removing battery box. If you have to go to next step you can remove TCI and open it to see if there is water in it or has been. I think there is a thread on opening the TCI and baking it in the oven. Not as scary as it sounds. I haven't had much luck with that but others have. Just go at it step by step and we will get it. Removing TCI now will let you move it out of the way of all the water that it gets where it is and its a lot easier to clean those connections with it out of there.
