Stop Solenoid; General Information - Volvo Penta TAMD71B Instruction Manual

11.3 Stop solenoid

For emergency stop
The stop solenoid is located on the exhaust
manifold diagonally above the injection pump.
This solenoid is engaged through autostop or a
separate emergency stop button.
When the solenoid is activated, the injection
pump's control rod is moved into the zero deliv-
ery position and the engine stops as the flow of
fuel is cut off.

11.4 General Information

Electrolytic corrosion
Your engine has sacrificial anodes made of zinc as protection against galvanic corrosion. This protec-
tion may be rendered ineffective if there are any leakage currents from the electrical system due to
faulty equipment or incorrectly connecting electrical components on the negative side (grounding, pro-
tector ground). The following should always be observed:
The main engine switches should be mounted on both the positive (+) and the negative (–) battery
leads. The main switches should break the current to all parts consuming electricity. Electrical leads
should be fitted in such a manner that they are not exposed to moisture.
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 battery'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 require-
ment for extra current. The main switches to must be switched off when the engine is not in use.
The engine package must not be electrically connected to other equipment. Nor should it be used as
ground for radio or navigational equipment or other electrical equipment where there are 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.
A transformer connected to shore power must be installed so that the protective ground terminal on
the inlet side (120/220V) and the negative connection on the outlet side (24V) are not cross-connect-
ed.
Warning! Electrolytic corrosion as a consequence 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 qualifed or experienced persons. Installation or work on the
shore power equipment may only be carried out by electricians authorized to work with high-
voltage installations.
