Hi Dogman and others,
It's been a while since I've been on the site but needing advise once again...
I've had the Crystalyte 24-72V 20Amp controller on my bike for a little over a year... Last rode the bike a few weeks ago... Charged the battery (my ping and my stock one)... When I turn on the controller, the on/off red light comes on very weak and then fades off (within 2-3 seconds)... I checked the connections and they were OK.. Got the same problem with both batteries.. I guess something inside the controller has gone bad... What do you guys think?
As always, thanks for helping out... I think I'm back to Bernson EV to buy the Wilderness Energy heavy duty one he sells.
