I2.1. Checking and maintenance of
battery
A3565--- 130
--- Check the charge of the battery with an acid tester. Min.
1.23.
--- Check fan belt tension.
--- Keep the battery clean. It can be washed with lukewarm
water after removal from the tractor (always disconnect
thenegativeleadfirst).
--- Also clean the pole studs, the cable terminals and the
battery retainer thoroughly. Wash off oxidized spots with
water.
--- Wipe the outside of the battery, and coat the pole studs
and the cable terminals with petroleum jelly.
--- Refit the battery (always connect the positive lead first).
DANGER: Avoid sparking or naked flames
near the battery. The battery gives off
hydrogen gas which is highly explosive. The
battery electrolyte is corrosive.
I2.2. Alternator
AI8
The tractor has a negative---grounded alternator which
can easily be damaged if an incorrect connection is made
in the electrical system. For example, connection of the
battery with wrong polarity can burn out the alternator or
rectifier. The electrical charging circuit must not be
broken when the engine is running.
I2.3. Safety precautions for the
electrical system
--- Always connect the battery with the correct polarity.
--- Disconnect the negative lead of the battery first and
connect it last.
---Never brake the charging circuit while the engine is run-
ning.
--- Disconnect the battery negative lead before removing
the alternator from the engine.
--- Arrange enough ventilation to prevent the build---up of
explosive gases in and around the battery.
IMPORTANT: The battery leads (negative first) and the
alternator wiring must be disconnected before arc welding
is carried out on the tractor or an implement which is
attached to it.
Never run the engine with the alternator disconnected.
Do not connect any additional electrical equipment, as
this may damage components of the existing electrical
system.
