What does the battery test report say?
I found a test report where someone should fill in the blanks, but all I have is what I found in my testing. The charger bulk rate is 14.5 then drops down and from a month ago it was 13.5 float (which is good)
Give it more time and it would drop further. Currently when charger goes to float it starts dropping faster to where it's below 13.
When I plug the charger in there is a good spark from the plug and it never did that before, so the charger is drawing so amps.
When motors start there is a double beep with no code or error showing up anywhere, so I am assuming this is low voltage warning. You can see from the pic I posted previous that the ALT output is 14.5 but vessel view is seeing 14 to 14.1 while cruising. I have not seen voltages anywhere near 13V even after cruising some time and then measuring once stopped. In short the Bats voltages keep dropping each time I measure
I don't know how to fix or get info to prove it's not my charger. I to don't understand how fully charged Bats will not be able to use a single 20 amp output and not keep up with float. That said Odyssey has a list of approved chargers and at least this time I will install one of them. My cruiser didn't have any issues using same Bats but it was a 50amp total 3 bank charger. My seadoo got 9 years from the Bat and it was 23Ah and I used a 5 amp charger during winter, so it met the 10% rating (needs 2.3 amps)
I am talking direct with Odyssey
