1240p high voltage

100' of extension + a couple connections +30 feet shore power cord + x ft of internal wiring? You are looking at a significant voltage drop over that distance. Assuming you had at least 110 VAC (not a given in a boat yard) at the outlet, you could be getting into the realm of where the charger no longer can function properly. A 100' 14ga extension cord will cost you about 6% of your voltage. All the other wiring will cause more and cumulative loses.

Check the AC voltage at the charger when at the boat and post up what you have. The further you are from 110-120 VAC the more issues you will have.

yep, I feel silly for not checking that first. The charger says it will function down to 100VAC but like you said we could be well under that. Hopefully we don’t have a problem at all and I’m chasing a ghost
 
Well, here’s a really stupid one for you guys.

the voltage in the yard is a little off, but I’m seeing 115vac or so -

I did a bunch of nonsense, took the charger out, back in, tested to isolated batteries, etc. after 2-3 hours of messing around I decided to unplug the temp sensor lead. And there it goes, right down to 14.7v. Plug it back in? Back up to 15.1.

I have to get ahold of promariner to see if that’s by design but it seems like a defect
 
I seem to recall some type of "equalizing" mode... or something like that... where it would put out a higher voltage for a certain amount of time and then revert back to normal charging. I think you have to initiate that, though. But check on that - take a look through the manual, if it's what I'm remembering, I'm sure it's in there. Possibly the temp probe has to be installed for that function? But again, double check me on all of this.

I am like Dennis. I installed a new ProMariner Charger some years ago. A 1230P I think. You have to manually put the unit in Equalization mode. I never did it while I owned the boat as I did not feel it needed it. You likely just need to get it out of that Mode into a normal charging mode and all will be good.

I believe you will find that the bulk charge rate voltage can be higher when battery temperatures are monitored. The main reason bulk charging is limited to 14.7 to 14.9 is to prevent the battery from overheating. This has nothing to do with equalization.
So make sure you have the charger configured for the batteries you have then leave the batteries charging where the charger wants them to be and watch for a couple of hours to make sure it goes into absorption mode; you will see a drop in charge voltage.
 
Thanks guys - it’s not in equalization mode (at least according to the display).

I have a voicemail into support to confirm what ttmott is saying in terms of charge rate. I’m glad I don’t have an issue with the boat, but if this is normal behavior I wish it was in the manual :)
 
Sorry for the firedrill all, turns out everything is just fine. Below is the confirmation from support and the temp correction is working as intended. It was increasing the voltage up to its +.5v max. Next time I'm there I'll heat the probe slightly to see if voltage steps back. Hopefully this thread helps someone else who might be installing their charger in the snow :)


Mr. Strecker,

There is no compensation at 25 deg C. The max/min temp. compensation should be +0.5 and -0.7v

Regards,

Lower temperatures do require higher voltage and vice versa.. that would make sense. Just a quick search gave this table...

I don't see a temperature correction chart in the ProNautic manual, that would be helpful.

i made that suggestion to the tech. It seems so obvious now, but that’s usually how it goes.

I wasn’t going to replace the generator battery but I’m going to swap that one out too since I pulled it out in my fit of unnecessary troubleshooting. It had a deep cycle in there which seems silly.
