Merc 250 Verado Fuel increase

[alldodge]

Just found the fuses

 

[alldodge]

Checked fuse and it's good
Run test with just starboard running and it does get louder, it's just not as quite as port motor. Also did tested the ASC with Techmate and it passed, so no real problem. Will go back down in a bit to see if it actually reads the AEV or ASC parameter

Did find another Fault 4602 which I think is the low voltage
Took a bunch of pics to send to Odyssey to find out if they can determine did my $200 charger damage $900 (edit) $1713 worth of Bats

I'm not incredibly familiar with the terminology nor am I sure I am remembering correctly but... Last year weren't you seeing a difference on the DataStream with the exhaust open/closed at wide open or something to that effect? (I would expect that to make a difference normally, but just reading through I thought I remembered that happening) I don't suspect that is your issue, just found it interesting if I was remembering correctly that you seem to be seeing a sound difference between the two engines with it open/closed as well now....

I'm not remembering anything with a datastream issue, but being old and suffering from CRS doesn't help

The motors are said to have no effect on performance with the exhaust open or closed

That's what I'm remembering. Drop in load or commanded load or something that seemed to contradict the "no performance change" lol. Not a data stream issue.

Most likely a nothing burger but reading through this is thought I may have remembered something critical when in fact, I just remembered something.

Oh that's demand liner, demand, and demand Guardian
I will use those readings to find out if my change it props is a good or bad thing. I do like the way the Mirage props bit better backing up over the Rev4

@muc looked for AEV and ASC and found neither. All I'm seeing is exhaust on/off and test kind of things

Well Odyssey says my Bats were damaged by my charger not being able to supply "enough" amps. Bat charge mush be able to supply at least 10% of Ah rating, so 31M is 100 Ah which needs at least 10 amps. My charger is a 20 amp total 3 Bank. So I come back in all charged up but still need 10 amps minimum per bank

So here comes another 2K for Bats and charger

 

[alldodge]

Well $1700 on Bats and $200 on Charger and we'll try it again
Odyssey mentions Minn Kota 3 bank 10 amps per bank

What does the battery test report say?
The 10% is a recommendation NOT a requirement!
You're good as long as your batteries get to float voltage before you use them again, Odyssey can deny warranty for many reason per their terms but as long as they get charged completely before the next use. That's not "abuse".
Open circuit voltage 10.5V and below is a big problem, but if you've never done this. Shouldn't be a problem.
Have you gone straight to Odyssey?

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

 

[alldodge]

Full charged true AGM list 13V for full charge, and find readings of 12.9 on the net depending on where you look.

I left Bat charger off but connected to boat for 1.5 days. Charge measures 12.78 to 12.8 which to me should be fine, so why does VV give me 2 beeps when motor is started.

I'm not sure you have a battery problem. Here is something I found in one of DTS service manuals.

Additional Horn
Denial: A double rapid horn indicates denial of the attempted action.

To help me better understand your boat;
Can you post some pics of your dash? Need to determine what exact throttle control you have. (there appears to be 4 different possibilities) Also what all is installed on your boat, active trim panel, keyless, 1st mate, etc. What VV do you have? Do you have vessel view mobile or smartcraft connect?

Can you tell us your exact starting sequence that results in the double horn? Have you tried using the keys and starting port first, stbd first? When you use the button on the ERC, does one engine start first?

 

[alldodge]

Don't know which model VV it is, but can remove to get model number off back tomorrow if needed. Voltage readings at Bats with Bat switches OFF were 12.81 on motors and 12.84 on house.Turning Bat switches ON remained the same. After starting motors and then turning them OFF but key ON. shows 13V


Throttle control



Throttle control id dual with push button start/stop. It had a software recall on it and dealer said they installed it when they where doing last lower unit replacement. The recall had to do with the control not shifting the motor during docking procedures. It would do a 2 beep and the drive would not engage. It happened to me once prior to taking back to dealer. I had to move it to neutral than back to reverse to engage.

The last time out I shifted to reverse and heard 2 beeps backing out of slip, it was backing up so I didn't go to neutral. Could be one of the motors didn't shift but I didn't notice any difference

I have smartcraft, Vessel View, Vessel View Mobile and Ist Mate.
Merc Tech from Knoxville came up to install 1st Mate and noticed when keys were turned off, VV was not powering off. He said that Chap did not rig the boat correctly and it would take to much re-rigging to do it correctly, something about voltage was not dropping below 5V enough to make it happen. So he installed VV mobile along with 1st Mate to make voltage drop lower

Start sequence
Turn port than Strb keys on
Press start/stop on ERC, port starts first than Strb.

Stopping just press start/stop

In splash well there is a label stating something like start port first

If I start port with key first, I don't always hear the 2 beeps, need to do it more times to verify this is always the case.

When I start port the voltages are the same showing both 14.4V.


If I start just the Strb I see the below
So it's like the ALTs only work when the port is running
