I believe I have a bad bank on my battery charger. I have a ProMariner ProTournament 300. I just bought new batteries, went out a couple times and noticed my batteries were getting weak after short use. A while back I noticed that my charger immediately started in the “blinking red light” phase but after reading the ProMariners site, I thought this was normal. This weekend I got out fishing and found that with the motor cranked all the way to 100, I couldnt hold in 10mph wind. I went home and plugged in and again, immediately to the red blinking light. I came back and checked about 14hrs later, the charger still had a blinking red light. I went and tested the motor, and it would barely spin on 100. So I hooked my portable charger up to trolling motor battery 1 (of 2) and it went to a green light after about a minute (so I figured that battery was fully charged). I then hooked it up to battery 2 and it started taking a charge. After about 10 mins of charging (still taking a good charge at this point) I went and checked my trolling motor and it seemed like it had at least 75% more power, it was spinning pretty fast now. I left the charge on overnight and checked again about 13hrs later and it was still taking a charge. I am now concerned that battery is damaged, but maybe it was so dead that it takes 13+ hours to charge????This indicates to me that I have a bad bank on my charger, and now possibly a bad batter. Is there a good way to test the charger with a volt meter? What should it read on each of the banks? Should I hook up directly to the leads?? I dont want to blow up my volt meter so please advise.Thanks,Kent
