v boost controller

[merc49]

My controler has to be lightly tapped to get it to work when key is turned on.how can i fix this or does it have to be replaced.the previous owner had the boost unplugged so it was open all the time.it started overheating once the air temp warmed up so i plugged it back in.it ran great but only when it was cold outside.

Start by resoldering the connections where the main wires enter the board.
