High Engine Temperature sensor input. This sensor can be the resistive type
(Sender) or can be the switch type. The proper type of sensor must be selected during
GSC300 controller programming. The sender or switch must be connected to ground
for proper operation. If +Battery is connected to input terminal this can result in
damaged to GSC300 controller. When using a sender, the proper sender manufacturer
must be selected as each sender manufacturer’s characteristics are different; the
sender failure set-point must also be selected. When using a switch the switch must be
the NO type on normal engine run and close to ground on failure.

Fuel Level sensor or Auxiliary failure input. This sensor can be the resistive type
(Sender) or can be the switch type. The proper type of sensor must be selected during
GSC300 controller programming. The sender or switch must be connected to ground
for proper operation. If +Battery is connected to input terminal this can result in
damaged to GSC300 controller. When using a sender, the proper sender manufacturer
must be selected as each sender manufacturer’s characteristics are different. When
