2019 Ranger Tug 27- Battery Charger

[Esperance]

Hello everyone- quick question for the group. I have a Kisae 20A battery charger which stopped working. It is showing Code- E03. According to the Kisae manual, that code is "Battery is connected backwards". I double checked all of the connections and I am sure that nothing is connected backwards. Anyone run into this previously? Thanks.

Did you ever get a answer?
This is happening to me now. Double checked all battery connections. I did just replace the house bank batteries. I have no idea why it thinks it is reversed?

I fixed my E03 problem.
Procedure:

• Turn OFF/Disconnect AC
• Disconnect Channel 1 (House Bank Positive)
• Wait 10 seconds
• Reconnect Channel 1
• Disconnect Common (Ground)
• Wait 10 Seconds
• Reconnect Common
• Turn ON/Reconnect AC

Fixed.

Seems to me it was mad that I essentially replaced all battery banks, and E03 is a default (I don’t know what to do) Error code.
