What was found
(CAN) THERE IS A POSSIBILITY OF A SHORT CIRCUIT OF WIRING IN THE STICK GRIP ASSY. IF THE AIP DISC SWITCH IS INSTALLED AT A CERTAIN ANGLE AND THE TERMINALS ARE LEFT TOO LONG, IT CAN CONTACT THE PTT SWITCH AND CAUSE THE GRIP TO GET QUITE HOT. THIS HAPPENED AND DID NOT CAUSE ANY VISIBLE ARCING OR TRIP ANY CIRCUIT BREAKERS.
