Central electrics unit
The central electrics unit based on pc-board
design is located on the engine. It accommodates
the engine control unit, relays, diode group,
fuses for the glow plugs and the fuse for the fuel
pump as well as the MDC main fuse.
Two electrical terminals connect the unit to the
engine. In addition, there is also an oil and water
resistant connecting cable leading to the control
panel.
Earth cutout relay
The engine is earth-free in order to protect the
drive train from galvanic corrosion.
The earth cutout relay closes when the engine is
started. The engine is thus temporarily connected
to earth for the purpose of powering the starter.
