Wiring for a volvo penta 2003 marine diesel

Anyone familiar with the wiring circuit for a volvo penta marine diesel 2003 non turbo? Mine has a special elctrical system to prevent stray current from the starter circuit and uses two solenoids. All the manuals I have seen show a single solenoid. I believe the engine is a 1993 model. I am not sure which wires go to the solenoid which is not attached to the starter motor? I think the B- from the alternator goes to one of the main solenoid contacts other main contact is connected to the battery negative terminal. A red and yellow 1.5mm wire goes to one side of the energiser coil and is positive. The negative side to the energiser coil is to/from where? I guess there should also be a lead from the B+ terminal of the alternator but where does this go?

SOURCE: Converting From 12/24 to Starght 24 Volt

The batteries must be connected in SERIES. The method described is proper, but the name of the method is wrong.
On the female plug for the motor on the boat, if you have the wiring for TWO separate batteries coming to the plug, the male plug must have a jumper in it. To find out, disconnect the batteries one at a time and voltage check to see if there are two separate battery systems there. There probably are. If so, the series circuit is provided for in the male plug by the jumper and not in the back of the boat where the batteries must be wired independent of each other.

SOURCE: battery to starter motor.

Just to be clear, the starter should have a large terminal (where the battery cable connects) and a smaller terminal (where the activation wire connects)
The starter is grounded via the mounting bolts.
The activation wire runs from the starter to the starter switch.

Has anyone got any information on crescent outboard engine 18hp


Crescent was made by Volvo. Production was discontinued in 1978, however many parts interchange with other Volvo-Penta models/names. You can try a company called Discount Marine Parts. They carry many discontinued parts for these and may have manuals and diagrams as well. Here is a link to their info page on Volvo/Crescent.

Contact information as well as a link to their Home page for parts are at the bottom.

Volvo 2003 marine diesel problem starting


It sounds like you need to vent the pipe before the fuel lift pump so the vent is open when the pump is off. That way the fuel can not siphon to the lower tank. Then you would need a valve in sync with the lift pump to close the vent so the pump can draw. Perhaps there is a lift pump with that feature built-in.

Volvo Penta marine diesel 2003T engine has diesel in sump


I owned one diesel engine. I would say the engine siphoned the diesel after it was shut off.
The throttle controls may not be closed. The injectors were tested for their opening and spraying, but were they tested for closing and sealing when off? Diesel fuel lines maintain a vacuum or they get air bubbles. Cooling cylinders create a draw right into the crankcase. Last idea-crankcase vent clogged
