I have a triton tri pro three bank charger two of the banks will green light but the third bank flashes one red led. I checked the fuse and the water level is fine. any ideas?
Reversed polarity on the charger leads perhaps? Bad battery (shorted cell or just gone to battery heaven)? Some chargers require a certain battery voltage level before it will begin charging. If that battery is bad, it will not accept a charge nor can the charger begin charging.
