19
Q

Why isn’t the radiator circuit open at all times?

A

To allow for the engine to warm up quickly

20
Q

What temperature does the thermostatic valve activate the radiator circuit?

A

80* C

21
Q

What is the cabin heat exchanger?

A

A circuit that provides warm air for the cabin

22
Q

What type of oil system does the engine have?

A

Wet sump

23
Q

Voltage of electrical system

A

28 Volt DC System

24
Q

How is power provided to the electrical system?

A

70 ampere alternator (mounted on the bottom left side of the engine).

25
Q

How is the alternator driven?

A

Flat-belt driven

26
Q

What happens in the event of a main battery failure?

The field of the alternator is energized by two 12V 7.2 Ah sealed-lead-acid batteries (ECU backup batteries)

27
Q

Main battery specs

A

24V 13.6 Ah lead-acid battery

28
Q

What would happen in the event of an alternator failure?
