IMI AE06 Auxilary Electrical 3 of 3

When disconnecting a battery, you should always....

• Remove the ECU fuse to protect the ECU from a current surge

• Ensure you pull the fuel pump fuse first.

• Disconnect the positive terminal first

• Disconnect the negative terminal first

The 'best' and 'most accurate' way to check a glow plug is with a:

• Diode

• Zener diode

• Rectifier

• Light -emitting diode

When discussing the properties of a NEGATIVE temperature coefficient (NTC) Thermistor......

• As the coolant temperature increases, the resistance decreases

• As the coolant temperature increases, the resistance increases

• As the Coolant temperature increases, the resistance stays the same.

• The resistance does not change, regardless of engine temperature
