Have Boat Questions? Ask a Boat Repair Expert.
Hello, my name is***** will assist you.
At about what RPM are you getting the alarm?
Would you please post the serial number of the engine?
Looking at the coils on the engine, are they with 5 wires? If so, can you read the embossed numbers that are on them and let me know what they are?
How is the engine running when this happens?
Does he boat have a volt meter, and if so what does it read when this happens?
It would be a 4 beep.
Can you run the motor on a hose and use a multimeter to test the voltage right at the battery? This may just be that he needs a larger rated battery for the system that he is using.
I would just go with something like a 800 CCA/ 1000 MCA battery. If you added a second, you should also add an isolator to not burn up the charging system.
I should be on here all day tomorrow. Let me know what you find out on the battery voltage.
Ok, look on the left side of the engine and locate the voltage reg. It is a 2 inch square box. See if there is a fuse holder near it, and is that fuse still good.
looks like this one here.
The numbers are fine. I was just using the pic as a reference.
Did you charge the battery over night, or has he ever been stuck while on the water due to a dead battery?
Still have that multimeter?
If so, on the voltage regulator, disconnect the red going to it. then using the meter set to resistance, place the red meter lead in the red regulator wire, and take the black meter lead to the metal case of the regulator. Do you get a reading there?
Ok, can you try the same test on the yellow wires?
Ok, thats good.
The alarm had to be caused by the low voltage on the battery. I would still look at getting a larger capacity battery and running it.
Yes it should have.
The first test that you did on the regulator showed that it is grounded, The one that I sent you in the link is a direct replacement and is much less that the factory one. CDI makes very good products and they have a good warranty as well.
The regulator and I would also recommend the bigger battery for when the engine is not running and the sound system is.
Have a good one as well.
