In the TAMD71B the fuses are located in the front of
the junction box on the left end of the expansion tank.
The electrical starter element is also protected by a
strip fuse (150A) between the element and the high
tension relay.
The TAMD63, TAMD73 and TAMD74 have the junc-
tion box on the exhaust manifold at the rear left of the
engine. The fuses are at the back of the box.
In the junction box there is also a replaceable safety
fuse (8A) for the fuel shut-off valve on the TAMD71B
and a replaceable safety fuse* (7.5A) for the EDC
power supply on the TAMD74.
See instructions on page 71 for resetting/replacing
fuses.
Make sure that you always have spare fuses on
board.
* TAMD74: If the fuse blows the engine stops.
The main switches should break the current to all
parts consuming electricity. Electrical leads should be
routed so that they are not exposed to moisture and
there is no risk of them being exposed to bilgewater in
the keelson.
If there are several battery circuits, there must be
separate switches for the extra equipment. There
must also be a main switch between the extra bat-
tery’s positive (+) pole and the fuse block for the
boat’s electrical equipment. The main switch for the
extra battery circuit should break the current to all
power consuming equipment connected to this circuit
and be switched off when there is no requirement for
extra current. The main switches to the engine must
be switched off when the boat is not in use.
The propulsion unit must not be electrically connected
with other equipment such as trim tabs, steps, etc.
Neither may it be used as ground points for radio or
navigation installations or other electrical equipment
with separate ground cables. All separate ground
connections should be collected together to form a
joint ground connection which is separate from the
propulsion package.
If shore power is connected, protector ground should
not be connected to the engine or to any other ground
on the boat.
Transformers connected to shore power must be
installed so that the protective ground on the input
side (120/220V) and the negative connection on the
output side (12/24V) are not connected.
Warning! Electrolytic corrosion as a conse-
quence of leakage currents may cause serious
and expensive damage to your boat’s equipment
within a short time. Work on the boat’s low
tension circuit should only be carried out by
qualified or experienced persons. Installation or
work on the shore power equipment must only
be carried out by electricians authorized to work
with high-voltage installations.
Relays
The relays are located in the junction box. This is
located at the rear of the exhaust manifold on the left
side of the engine (TAMD63, TAMD73 and TAMD74)
and on the left end of the expansion tank (TAMD71B).
The start and stop* functions are controlled via two
change-over relays. These relays are identical and are
therefore interchangeable if necessary.
On TAMD71B engines there is also a timer relay in
the junction box which controls the starter element’s
engagement time via a high tension relay (approx. 50
seconds). This high tension relay is located in front of
the air cleaner (ACL) adjacent to the starter element.
* Not TAMD63 and TAMD73WJ engines.
General Information
Electrolytic corrosion
Your boat and its engine/reverse gear have sacrificial
anodes made of zinc as protection against galvanic
corrosion. This protection may be rendered ineffective
if there are any leakage currents from the electrical
system due to faulty equipment or incorrectly con-
necting electrical components on the negative side
(grounding, protector ground). The following should
always be observed:
The main engine switches should be mounted on both
the positive (+) and the negative (–) battery leads.
Electrical system – Important!
Turn the engine off and switch off power at
the main switches before carrying out work
on the electrical system.
1. Main ON/OFF power switches
Never break the circuit between the generator and
batteries while the engine is running. In other
words, the main switches must never be discon-
nected before the engine has stopped. If the
circuit is broken while the engine is running, the
voltage regulator may be destroyed and the
generator seriously damaged.
Charging circuits must not be switched over while
the engine is running, for the same reason.
