Dual pro battery charger question.

7 posts in this topic

I have a three bank dual pro charger in my boat. The two banks for the trolling motor batteries seem to work correctly, but the third bank for the cranking battery keeps all 5 red led lights on permanently. I charged the battery the old fashion way with an old school charger to full, plugged the dual pro back in, same thing 5 led's on a full battery. I looked on their HSOforum in the trouble shooting section and it gave no indication as to what could be the problem.

Anyone with any ideas?

If it is a Minn Kota, according to the manual that you have one of three problems:

A RED light for each bank is lit if any of the following apply:

a) No battery is connected to an output cord. This may also indicate a blown fuse in the fuse holder.

B) The battery voltage is below 8.0 volts.

c) The battery is connected reverse polarity

It is a dualpro, so I think those are out. I did remove the in line fuse, and all five ofthe led's went out.

Throw a meter across the battery when you first plug it in and agian after the other batteries are done. You could be getting the proper charging voltage and the LEDs are goofy, or the charger could be giving you 15 volts all the time and that will kill your starting battery.

mnfishinguy, yeah, I figured I would do that eventually, but I thought it may have been an issue that had come up with someone else.

My charger (not a pro charger) dosen't change from red to green anymore. I've got it on the charger right now to see what it does on the meter.

If all else fails get a hold of Dual Pro - they're pretty good about standing behind their product.

    • My family is going to be headed to Birch Lake near Babbitt, MN in late June for a week on a houseboat.  This trip is a graduation present for our oldest and I am hoping to make it a week to remember.   I would appreciate any advice ranging from fishing locations, bait, suggested lures, and even sites to see on the lake.  I have done a lot of searching on Google with the hope of finding someone who maybe spent a week on a houseboat on Birch but not a lot of luck.  I have about a month to prepare for the trip so I greatly appreciate everyone input.   Thanks,  
    •     I have had good luck with the "My Plate" app.... It is annoying enough to keep you honest, but simple enough to use.
    •   Yeah well once you fire that bad boy up and show her how it works, she will get impressed pretty quick! 
    • In regards to casement windows, I have always been a fan.... Primarily, because the harder the wind blows, the better seal that you are getting. Don't get me wrong - there are drawbacks such as size restrictions, maintenance of the cranking mechanism, etc... but I like them
    • walleye, Pfunk, monster, we need one more bird to qualify for bragging rights.  You guys still after them?
    • Kept getting pushed back from moving into the new house, but finally heading up to open the camper tomorrow afternoon.  Bought a new leaf blower to keep the outside rugs clean.  On mega clearance at Wally world for 10 bucks...  Told the Mrs. it would've been foolish of me NOT to buy it.  She wasn't impressed.
    • Rot can also be completely separate from the quality of the window.  If you maintain high moisture in the house it will first collect on windows then can drip down and rot out the surrounding frame.
    • Well it looks like you have already found your plumbing company!
    • On the cheat meal issue.  There is only a minor setback physically if you limit to once a week.  What most people don't look at is the psychological benefit to a cheat meal.  The truth is most people who run a diet(excluding athletes and those that maintain a fit lifestyle for prefessional reasons) sneak snacks hear and there.  Sure some dont or dont for a time but most do.  The cheat meal gives you one day or meal all week to look forward to with those snacks to splurge.  This is by far easier than someone saying the diet is three months, or even better, 'I'm never eating processed sugar again'.
