## Discrepancy

INVESTIGATING AN INOPERATIVE GLARE SHIELD LIGHT, FOUND THAT THE WIRING BUNDLE HAD CHAFED AGAINST THE THROTTLE HOUSING BEHIND THE INSTRUMENT PANEL, SHORTING THE CIRCUIT.  SEVERAL WIRES WERE DAMAGED.  THERE IS NOTHING TO PROTECT THE WIRES IN THIS AREA SINCE THEY ARE LEFT LYING LOOSELY ON TOP OF THE THROTTLE HOUSING.
