    Alternator and fuel pump on Volvo Penta 3.0 GLP-D

    Apologies, my actual numbers are closer to the ones you mention, yes. Resting battery - it has taken a battering after all the trials and haven't been recharged yet - 12.4 V On alternator - idling only, ~800 RPM, on garden hose - 14.2 V The internal resistance of my bilge blower is 0.6 Ohms...

    Alternator and fuel pump on Volvo Penta 3.0 GLP-D

    Should read flinches slightly at the trim, 0.5 V, but comes back.

    Alternator and fuel pump on Volvo Penta 3.0 GLP-D

    Hi all, thank you everyone for your advice. Everyone's suggestions was acted upon, and investigated, (Lou C, alldodge, MarineSp, Grub54891), and all this helped in what it seems is isolating the issue. The culprit seems to be the blower, or some other component on the same circuit. Blower...

    Alternator and fuel pump on Volvo Penta 3.0 GLP-D

    Thank you. I'll keep checking, and will clean other connections as well. Will attempt disconnecting the bilge blower, to see if that makes a difference. Bilge water pump, nav/anchor lights, drive up/down switch did not have an effect on the voltmeter's 14V, only the bilge blower was knocking it...

    Alternator and fuel pump on Volvo Penta 3.0 GLP-D

    An update on the above issue. I will probably wait until I can take the boat to the mechanic, as I am afraid of doing further damage....might have already done it. Tried peeling back the insulation tubing on the wire on the right, I stopped at the zip-tie in the image. I will go further once I...

    Alternator and fuel pump on Volvo Penta 3.0 GLP-D

    Thank you. I have to correct my earlier update. The fused line from Battery+ was not connected to the alternator terminal where the sensing cable connects, but to the sensing cable (brown with white stripe) itself. I am now confused as to how did my engine start and why does my dash voltmeter...

    Alternator and fuel pump on Volvo Penta 3.0 GLP-D

    Update: connected a fused line from battery plus terminal to the sensing port of the alternator (which shows 0 V, and it should show 12 V), started smoothly, and both dash voltmeter and multi-meter show 14 V. Am I too irresponsible going out to a sea trial? Good weather, member of marine rescue....

    Alternator and fuel pump on Volvo Penta 3.0 GLP-D

    Thank you, hopefully we will up and running, and back to 14 V on the gauge!

    Alternator and fuel pump on Volvo Penta 3.0 GLP-D

    Thank you for the useful info. Whether I have a mechanical pump or not, not sure, I can only see a single fuel line coming from what I suppose is the electric fuel pump. Unless the mechanical pump is the one I use to "prime" the cold engine. Could not see any fuel coming through the disconnected...

    Alternator and fuel pump on Volvo Penta 3.0 GLP-D

    After doing some fixes to my cooling system, I took the boat for a test ride. One of the first out-of-ordinary issues I noticed straight after launching and starting engine was that my dash voltmeter was indicating 12 V, while it usually indicates 14 V. The battery was charged, having spent the...

    Exhaust riser restrictor plate - Volvo Penta sterndrive 3.0 GLP-D 4-cylinder petrol

    Original Poster here with a new account, due to a lost and unrecoverable password. Just a follow up on this issue for others who might be experiencing similar symptoms. I have cleaned the exhaust riser extension and exhaust elbow, as well as the marine wet exhaust rubber tube connecting to...
