To simultaneously charge two independent battery
circuits, fit a Volvo Penta charge distributor to the
regular generator (accessory).
2. Batteries
Never mix up the positive and negative battery
terminals when installing. Incorrect installation can
result in serious damage to electrical equipment.
Refer to wiring diagrams. The battery terminal
posts should always be well cleaned and the
cable terminals well tightened and greased to
prevent open circuits.
Avoid boost charging the batteries. If the battery
must be booster charged, first remove both
battery leads.
NOTE! Follow relevant safety regulations when
charging batteries. When charging, unscrew filler
plugs but leave them in their holes. Ventilation
should be good, particularly if the batteries are
being charged in an enclosed area. Always switch
off the charging circuit before removing the
battery charger connectors.
Warning! Never allow an open flame or
electric sparks near the batteries. Never
smoke in proximity to the batteries. The
batteries give off hydrogen gas during
charging which when mixed with air can
form an explosive gas – oxyhydrogen. This
gas is easily ignited and highly volatile.
Always use protective goggles when
charging and handling batteries.
The battery electrolyte contains extremely
corrosive sulfuric acid. If this should come
in contact with the skin, immediately wash
with soap and plenty of water. If battery acid
comes in contact with the eyes, immediate-
ly flush with plenty of water and obtain
medical assistance without delay.
3. See separate instructions on this page for how
to start using auxiliary batteries.
4. Connecting accessories and extra equipment
All extra equipment should be connected to a
separate junction box and fused. Extra outlets
directly from the instrument panels should be
avoided. Permitted extra power take-off is howev-
er maximum 5A* (for all instrument panels togeth-
er).
* Note. For the TAMD73P and TAMD74 max. 2A apply.
Arc welding
Remove the positive and negative leads from the
batteries. Then remove all leads to the generator.
TAMD73P and TAMD74: Remove the connector from
the EDC system control module (located behind the
fine fuel filters). Pull down the red locking catch (A)
below the connector while pulling the connector out at
the same time.
Starting using auxiliary batteries
Warning!
The batteries (auxiliary batteries in particular) contain
extremely explosive oxyhydrogen gas. One spark,
which may be formed if the auxiliary batteries are
connected incorrectly, is sufficient to explode a
battery and cause damage and injury.
1. Check that the auxiliary batteries are connected
(in series or in parallel) so that their rated voltage
is the same as the engine’s system voltage.
2. First connect the red jump lead (+) to the auxiliary
battery, then to the discharged battery. Then
connect the black jump lead (–) to the auxiliary
battery, then to a spot a short distance from the
discharged batteries, for example at the main
switch on the negative cable or at the negative
cable’s connection to the starter motor.
3. Start the engine. NOTE! Do not shift the con-
nections when attempting to start the engine
(spark risk) and do not lean over any of the
batteries.
4. Remove the jump leads in exactly the opposite
order to which you put them on. NOTE! The
normal leads to the standard batteries should
under no circumstances be moved.
TAMD73P and TAMD74: Removing the connector
from the control module
A. Locking catch
Always connect the weld clamp to the component to
be welded and as close to the welding point as possi-
ble. The clamp should never be connected to the
engine or in such a manner that the current is able to
pass over any bearings.
When welding is complete:
TAMD73P and TAMD74: Press the connector into the
control module for the EDC system while pushing the
locking catch (A) upwards.
Always connect the leads to the generator
before replacing the battery leads.
