I have a 2000 225 OX66, 2 batteries with selector switch. I don’t think it is charging the battery and here is why. My guage on the instrument cluster starts out at about 12.2 and then after awhile it starts flashing, drops down to 12, 11.9 and now it is on 11.8. This is after running it for 3 hours, idle, cruise at 4000rpm and so forth.
I put my digital volt meter directly on the battery and it initially read 12.3 volts and when the guage shows 11.8, my meter directly on the battery reads 11.92V. My shop replaced the voltage regulato to fix the issue but I don’t think they fixed it. Shouldn’t the battery voltage be about 13-14V when running? Mine doesn’t.
BTW, I did change batteries and the other read 12.3 and I switched back to the original to be sure I had a good battery just in case. The engine turns over fine and the batteries were installed last summer.
Anyone know what voltage their OX66 puts out? Should I measure directly on the engine?

I need to be at or above 600 rpm in gear
It was low at 4000 rpm, 11.9V

It should be about 14.2V when running.

I need to rant. First let me say I am a computer tech not an outboard tech. My engine was not charging the batteries and I took it to my shop for service, told them the batteries were not charging and the idle rpm was too low. They replaced the voltage regulator and said all good.
It was not good and I did some research and the stator was putting out good AC voltage, 30-40 volts AC at 2000 rpm. I looked at thehulltruth.com and read where someone had the auxiliary charging wire hooked to ground. So was mine. If I can find it why can’t an outboard tech find it? Evidently the charging voltage was never checked when it was in the shop.
Now that my batteries are charging, where do I connect this wire? I have a Guest switch with 2 batteries.

This lead is, as it is named, “auxiliary charging lead”. Assuming you’ve got one battery for starting, one for accessories. This lead is used for charging the second (acc.) battery. You can get a ready made lead that is sized and fused for your motor. No need for switch, both get charged together.

FROM TEH FACTORY THAT WIRE WAS JUST DOCKED OFF
IN THE MAIN PANEL / RELAY THERE IS A “BRIDGE” THAT CAN BE CUT AND IT SENT HALF OF THE CHARGING SYSTEM TO THE MAIN BATTERY AND HALF TO THAT WIRE
IF THE BRIDGE IS RECONNECTED AND THAT WIRE IS DOCKED IT WILL SEND ALL THE POWER BACK TO YOUR MAIN BATTERY, OR AS WAS SUGGESTED EARLIER YOU CAN CHARGE 2 BATTERIES AT HALF THE AMPERAGE AT 1 TIME.
WHO CONNECTED THE CHARGING WIR TO GROUND?
ALSO, IF THE SHOP IS REPUTABLE, AND YOU PAID THEM TO REPAIR IT, WHY NOT JUST CONTACT THEM AND TELL THEM THAT THEY CHARGED YOU FOR A REPAIR, BUT THE ORIGINAL PROBLEM IS STILL THERE.
AS THE OWNER OF A SHOP, I KNOW I ALWAYS WANT SATISFIED CUSTOMERS, AND IF WE MAKE A MISTAKE, WHICH DOES HAPPEN SOMETIMES, I DEFINATELY WANT THE OPPORTUNITY TO MAKE IT RIGHT.

I assume the wire was connected to ground when I bought the boat, the previous tech for the previous owner who replaced the batteries evidently mis-wired it, not the current shop. My point is the shop replaced the regulator and all they had to do was put a volt-ohm meter on the leads to check their work.
I did contact the shop that charged me for the regulator and they said they would do something to make it right but I will question everything they do from now on.
