Hi, my display has red light on only, no other lights on except the display. When I turn speed knob there’s a click but numbers pop up erratically on display then red light stats flashing. The battery is fairly new (18 months and not used very much over that period) and when I try to charge it the green light is on all the time. Can you help?
This seems like a battery lead or connection issue. If the battery is definitely ok, then I would think the battery lead is at fault. I come to this conclusion from the fact of the charger not showing first a RED light when plugged into for charging. The RED light means the charge is getting through to the battery. So it may just need a battery lead, but I would still check the battery.
Thanks for the info, I have managed to spot a loose wire in the charger
When my charger is connected to the battery the green light flashes on and off but does not seem to be charging the battery,
Try another battery to see if it still happens, then if still doing it look at connector, then charger itself.
