Electrical system
IMPORTANT
3.
When starting with the aid of an auxiliary bat-
tery, first check to make sure that the auxiliary
battery has the same rated voltage as the
standard battery. Connect the auxiliary battery
to the standard battery with positive to positive
and negative to negative. Remove the auxiliary
battery when the engine has started. NOTE! On
no account must the cables to the standard bat-
tery be disconnected in this operation.
When carrying out electrical welding on the en-
gine or installation components, the charging
regulator cables must first be disconnected and
insulated. Both the battery cables must also be
disconnected.
Before carrying out any repairs on the alternator
equipment, always first disconnect both the bat-
tery cables. The same applies if the battery has
to be rapidly charged.
Never test any of the components with a screw-
driver or similar tool against a connection to see
if there is any spark.
The following applies to engines fitted with alternators.
1.
Never interrupt the circuit between the alternator
and the battery while the engine is running.
Otherwise the charging regulator will be ruined.
If a main switch is fitted, it must not be
switched off until the engine has stopped. Other-
wise no cable must be disconnected while the
engine is running, since this can also ruin the
charging regulator.

2.
Check regularly the battery, battery cables and
cable terminals. The battery poles should be
well cleaned and the terminals tightened and
well-greased to ensure continuous function. All
cables in general must be well-tightened and dry
and sprayed with moisture inhibiting spray.
NOTE! On no account must the battery’s posi-
tive and negative poles be mixed up when the
battery is fitted.
