    Need some help with a1977 Volvo Penta 3.0 Ignition System

    I am trying to help a fellow iBoats mbr sort through their Ign System issues. While the engine did run in his new to him boat, it would not a little later. Troubleshooting led to a no spark situation and a really nasty looking dizzy under the cap. So that has been replaced (entire distributor...

    Volvo Penta 3.0 4 cylinder engine won't start

    Dash, i think a new coil is a good idea. And agree that our terminology may be different. I have learned it is best not to post past my bedtime, so I will put another post up tomorrow with pictures and where to test +12V and spark as it does seem we are talking different things. 😊

    Volvo Penta 3.0 4 cylinder engine won't start

    The dist. and rotor location and the firing order all look good from the pictures so thank you for posting them. I am unsure what that picture ending in 306 file name is showing. What is that? Ok so to the problem. You say you are not getting spark to the plugs, but you do not say how you know...

    Volvo Penta 3.0 4 cylinder engine won't start

    I am glad that you were able to get it sorted out. I recall you do not have a helper and thus trying to get this started while slightly adjusting the timing and controlling the throttle I am sure proves difficult. While may be too late in the process, a remote starter like this link is a very...

    Volvo Penta 3.0 4 cylinder engine won't start

    Dash, The best video I have found for how this distributor is aligned is at this link. While for a Mercrusier, I think it’s the same. Watch from about minute 4 onward. Below is a screen shot of that video showing the alignment when fully seated. In summary: with the No. 1 Cylinder at TDC on...

    Need advice

    While the answer to your issue is the above posts, to answer your question > it depends on what your definition of a “solenoid hot wire” is. To help that, below are pictures of two types of starter solenoids. One with 4 wires, and more typical, a 3 wire. Post No. 1 in both pics is always hot as...

    2002 240 Four Winns Volvo 5.7 Penta winterization process

    More than likely the “boat owner’s manual” would not go into how to winterize so get the OEM manuals for the motor and sterndrive, see link. Also see this thread (link) post 87 - 89 about freshwater flush for the engine for next season start up, etc. There are two types and only one can be used...

    Another overheating thread - Please help - Intermittent/Random!

    I have not experienced a difference between OEM and Sierra branded impellers, other brands I have not tried / trusted. Adding to the idea of using a garden hose (if raw water cooled) into the hoses that go into the manifolds that kenny nunez is suggesting > the concept is there is a restriction...

    Volvo Penta 5.0 GL-D cranks, no start

    Do yourself a favor and especially since a project boat, get the OEM manuals for the motor and sterndrive, see link. Also, these wiring diagrams are like gold. So, until you have the manual suggest you download the above diagrams > with a PC right mouse click on the image and select “Save image...

    Volvo Penta 3.0 4 cylinder engine won't start

    Since I am not familiar with your distributor and coil set up I am assuming your coil looks like the picture below, so strip it of its wires (+ and – and High-Tension Lead) and test as indicted. If your coil uses a connector plug for the + and – same idea just need to figure out which is which.

    Volvo Penta 3.0 4 cylinder engine won't start

    Thanks for the update. I know you will get this going. Some things to note as a recap: Test the coil as described in post #20 Ensure you are at the firing stroke TDC using the finger method and then aligning the timing mark to 0. See post #22. And be sure you are turning over the engine in the...

    ACR with Inverter Question

    Thanks but I think you are misunderstanding. I am looking to know what will happen if it’s run like as outlined in post 1 (and not at 50%). More specifically I’m hoping someone with a similar set up can highlight what they did to avoid overloading their alt if fact it would overload the alt...

    ACR with Inverter Question

    Thanks for the input. While the Inverter will be pulling only about ½ of the Alt capacity that is not a guarantee. In other words, if the “policy” is do not turn on this or that on the AC side, it’s not a guarantee. So, I am looking to understand the limits in order to make the design as robust...

    ACR with Inverter Question

    Communication is hard, but yes that is what I am trying to convey in the hypothetical scenario above > that the inverter is trying to continuously pull 165A on the House batteries (which it can do to a point) but then the ACR relay closes coupling the House Bank to the Alt (via the Start Batt)...

    ACR with Inverter Question

    Yes, for a limited period of time. The question revolves around a continuous load greater than the capacity of the Alt in the scenario outlined above. Are you saying alternators are rated for 100% duty cycle? Thanks for your continued thoughts on this.

    ACR with Inverter Question

    Its my understanding that the Alts. are not designed for 100% duty cycle. Perhaps that is wrong, but i am under the impression that its about 60%.

    ACR with Inverter Question

    While this is a hypothetical question the answer will impact the design I am doing. I assume others have a set up similar to this so looking to understand what they did or perhaps my thinking is all wet. Scenario: Two House Batts., One Start Batt. all 12V lead acid type and same model, coupled...

    5.0 Ford MPI surging at idle and at 3500 rpm

    Let’s see if we can get the conversation started. My short answer is this needs to be scanned while running with the type that records. With that there are folks on the forum that can interpret those records and provide guidance. These are expensive but can also rent them (link). Barring that...

    Humor me with your whine theories, V8-380-CD

    I assume your engine is MPI since you mention fuel pump whine, thus my guess: Fuel Pressure Regulator in the fuel rail. Also one of those mechanics stethoscope with an air horn (as well as a rod) is great for initially localizing the noise and then go from there with the rod (Link.) once you...
