Took the boat out of storage and the green Error Indicator light flashes continously on the EL512 (installed 2002). The fuse is OK, all wires are connected properly.One 8D battery of two on the house bank is now indicating 110 degrees on the Energy Monitor EMONII-H1.To take readoings from EL512 I turned off the battery charger (40 amp True Charger multi stage) Taking voltage readings the green Error indicator light went out:

2-0
3-0
4-0

Please advise if EL512 Eliminator is working properly

The Eliminator appears to be operating OK.

It looks like you have a shorted cell in the 'hot' battery, or have been overcharging it for a long time.
