I owe Xantrex an apology - no reservations.
I was fuming that my Echo-charger had stopped working. I had checked and double checked all connections and I was 100% positive that my unit had seized.
Today I went out with the aim to tear out and discard my failed Echo-charger. I took out the fuses and proceeded to cut away the tape I had applied to secure all wires coming from the unit.
Then I come across 2 more wire connections that I didn't realize was there. One of them appeared loose. I take it apart and then reconnect it. The Xantrex unit starts flashing again
I made a mistake which I have now corrected but having doubted the product now proves to be an injustice.
My Xantrex unit now works again and it was only down to my own stupidity that I encountered this problem. Sorry Xantrex!!
