Dacă încerci să pornești motorul interior al bărcii tale și nu se răstoarnă, ce faci? A ști ce să verifici și de unde să începi este cheia pentru a te pune în funcțiune sau pentru a obține ajutorul potrivit, cât mai repede posibil. Matt Sheahan discută cu instructorul de iahturi offshore Bruce Jacobs de la Rubicon 3 (www.rubicon3.co.uk) pentru ghidul său de cinci minute pentru depanarea instalațiilor electrice diesel marine. Seria How To de la Yachting Monthly vă este adusă în asociere cu GJW Direct. GJW Direct oferă unele dintre cele mai cuprinzătoare polițe de asigurare pentru bărci de pe piață, la prețuri foarte competitive. Cu peste 175 de ani în asigurări maritime, ne-am dori să credem că atunci când vă asigurați iahtul cu noi, puteți fi sigur că aveți de-a face cu specialiștii în asigurări de bărci, lăsându-vă liber să vă bucurați de timpul petrecut pe apă. https://www.gjwdirect.com/ Acest videoclip a fost filmat înainte ca guvernul Regatului Unit să introducă măsuri de distanțare socială.

Check battery voltage while trying to start the engine. You might see the voltage drop significantly; a battery of that type is a "voltage source" as it will try to develop 12V DC across any load – even a dead short or very low resistance such as the winding of a starter motor. As such, with a weak battery trying to turn over a stubborn engine you might see the voltage drop to 4-6V which is a sure sign that the battery is in need of replacement.
You should expect to see the voltage drop 1V or so when starting, but consider anything under about 10.5V measured (with a quality meter such as Fluke) as a problem.
Also, you may need a very high end handheld voltage meter (or a very low-end oscilloscope) so you can check for other issues mentioned in this video. For example, simply measuring voltage at the alternator may not lead you to notice a damaged rectifier; a DC offset or leaking AC can damage some equipment.
When re-connecting a loose spade connector, surely you should crimp it otherwise it willl be a very temporary fix.
great stuff thanks!!
Great video nice and clear. Better seeing an actual engine and having it explained. Txu for taking the time to make this video regards from New Zealand
Thank you
Excellent presentation on electrical trouble shooting.
12.8 charging system voltage is not good, you should have 13.8
Question; I have a small 2 cylinder Yanmar in my sail boat. Each time I attempt to start the engine- the starter housing breaks. I have replaced 3 starters now. Its like it doesn't mesh correctly? Am I missing something?? The engine block where the starter is bolted seems clean and correct. Please help with any info?
Love this 👊🏻
12 volts coming the the altinator won't charge the 12 volt battery, you need 14+ volts. I like the out of the boat set up though.
Great info. Thank you.
So you started the engine to check if the alternator was working. But you were doing this whole thing to diagnose an engine that isn't starting. Top notch video.
4:35 Guvnah!
Very helpful, clear and to the point 👌
Checking voltage on a battery is not very helpful. You shoud check only under the load. Nearly dead battery can show you 12v but under small load such as light bulb can significantly drop.
I expect c.14V at the alternator when running…
What is the likelihood that the contacts within the solenoid is dirty due to sparking creating resistance & voltage drop?
If only it was so easy to access all the various component of the engine.
Good video, need to explain in more detail what you are checking, what is a "stop solenoid". Do all
diesel engines have these? 12.8v is not good, should be above 14v. Yachting Monthly needs
to review these video's before publishing them.
Hi! watched this video ten times now. gone through my engine and changed/checked everything in the fuel system except the injectors, I do not know how to do this. I have an old Volvo penta MD6. when the compression handle is lifted the engine turns but as soon as I lower it there is no more action, no combustion of fuel at all. it took longer and longer last summer to start it up, untill one day it didnt start at all. any help from anyone is very appriciated!
is the alternator bad if it is reading 15.8v with the tester?
Your alternator is broken, you should be reading from 13.8 volt to 14.7 volts
If I had the meter in my hand and had checked the battery voltage, it would be an obvious move to look for exactly the same voltage at the starter solenoid's heavy positive cable since they're usually directly connected. If they're not at the same voltage, check connections and integrity of the cable. This is worth doing anyway, since a dodgy cable will give you a voltage reading even if it's down to it's last strand of wire. It will never carry the juice to turn the motor over though.
If all looks good, bridge the two large terminals on the solenoid with a screwdriver. If she fires up, the problem is on the control side (ie from battery positive to ignition key, to smaller positive wire on the solenoid). So you've narrowed the thing down pretty easily.
Sometimes a few judicious taps of a light hammer on the body of a starter motor will persuade it to spin. Don't overdo it.
A stop solenoid, if it has two terminals, can be checked just by putting voltage on the teminals. The plunger should pop in and out as you do.
Hi. How can I check the electrics before the starter motor eg the push button and the cable that goes to the starter motor (the loose white one in this video) to make sure they are working properly?
Thanks Andy
Sorry, Checking the battery right off the start with a voltage meter is WRONG….. AMPS is the key , Even a dead battery reads 12.4 volts , Yes AMP testers cost money but worth every penny . Without AMPS you get no crank .
