Hello, I just recently purchased a 2000 gem 825 and replaced the batteries with flooded Duracell group 27 batteries. there were no batteries when I bought it. it ran great, the charge went down to 80 percent and I plugged in the 912-7200-02 charger and it looks like it starts to charge, than the red light begins blinking on and off. Can anyone tell me where I should go from here, thanks
Count the blinks. It’s an error code.
