LERT elec

Some manufacturers refer to solenoids as a contactor but both components essentially perform the same task.

• True

• False

NiCad batteries need

• Temperature monitoring systems

• Ventilation Systems

If there is no positive locking device on the battery connector

• use Loctite

• lockwire with 26 AWG safety wire

• torque to 30 inch pounds or above

If you spill electrolyte on your skin

• flush with vinegar

• flush with water

• neutralise with bicarb soda

Main purpose of a constant speed drive

• maintain generator frequency

• maintain generator voltage

• maintain generator current

IDG filters don't have bypass capabilities so if delta P popped (blocked), IDG needs to be replaced

• True

• False

Purpose of an equaliser bus

• tie busses in the event of a generator failure

• balance parallel generator outputs

• weakens both generator fields

The purpose of the surge quench diode in a transistorised voltage regulator

• increases the field strength of the generator

• protects transistor T1 from sustaining damage

The purpose of the permanent magnet in the brushless alternator?

• varies the exciter output

• controls the main output

• initial starting

Which bus has the higher importance/hierarchy?

• essential DC

• essential AC

• hot battery bus
