Minn Kota Onboard Charger problem?

[Minnesota Fats]

I have a Minn Kota Mk106 onboard charger. I plugged it in yesterday to top off the trolling battery, and when I went out to look at the boat tonight, I noticed that the charger was toggling between "Full Charge" and "Charging" every 4 or 5 seconds. I don't think this is normal, because I think in the past the "Full charge" light would come on and just stay there until it was unplugged. Anybody have a similar observation or know if this is normal or abnormal?

Not totally sure, but it may be that your battery is just dead. I think I have heard of this before. Call them up, sounds like a "trouble" sequence or something.

I will check into that. It is a new battery, by the way. I suppose I could have gotten a bum battery?

A GREEN power light is lit to indicate AC power is applied.

A YELLOW light is lit or each bank to indicate the battery is charging.

A GREEN light is lit for each bank to indicate any of the following:

1) The battery is fully charged and in maintenance mode.

2) There may be a blown fuse in the fuse holder.

3) No battery is connected to an output lead.

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

1) A short circuit.

2) The battery is connected reverse polarity.

Thanks

Mine is toggling between the Yellow and Green. I am going to connect it to a different battery tonight and see what happens.
