Hey all - I am a brand new owner of a nice 2007 GEM e2. Brought it home a couple of days ago and drove it around the neighborhood, plugged it in overnight. The next day I got about 2 miles down the road before it went into slow mode, and I had to limp all the way home.
Investigating… Noted that the charger would cycle on just like it should, with all lights blinking, and then getting the AC light and the #1 light. After a couple of hours I was getting a 4-blink red error code, which supposedly means that it failed to start charging. I found that the Delta Q Quiq charger was on algorithm 126, and that the previous owner had changed the batteries from Fullriver Gel’s to Delkor Flooded DC-31’s without changing the algorithm, so I went ahead and switched it to algo 13.
Now… When I plug it in, I get the LED cycling, and then the AC light comes on, but that is all. No charging whatsoever, no error codes… It just sits there with the AC light on.
Any Ideas on what to check? I am still at about 72 volts at the controller, batteries all test at about 12.3-12.4 volts (unloaded).
Thanks in advance to all of you rock star mechanics out there. I am blown away at the level of knowledge in this forum.
