hi thanks I don't get voltage (.05) with my multimeter, but someone told me I wouldn't get a reading because of how the battery is designed. I have 4 wired in parallel, the charger has an extension to charge them all on the trike, so what ever I did I did it to them all.
A suggestion was to "wake them up" with a solar trickle charge, or place a good one into the system and that would allow the others to charge.
Mostly I'd like to know if I fried something or just drained them and now need an awakening.
I wish I'd been more awake when I wired the plug.
