Heres a photo of the BMS. Have plenty of USB chargers, but not sure how to connect them. Thanks for your help.

Ok finally got the better cover off. Red and black wires are soldered to a board in the top, so could not disconnect. With black probe on plug with two black wires and red probe on various colored wires in plug on opposite side of BMS my voltages are: black - 3 brown - 7 red - 11 orange - 15 yellow -19 green - 23 blue - 27 purple - 31 grey - 35 red - 39 (two more yellow, also 39) Not been charged for 3 or so weeks, so may be a little lower than usual.

Update: one of the screws on battery cover is stuck, I cant get it off with the screwdrivers I have, so have ordered some more. According to 8fun they say it should be ridable down to 30V, and they advise me to check the connections. Could anyone let me have a wiring diagram? I did ask 8fun , but no reply so far.

The battery is not taking any more charge, light stays green on charger, Just got the multimeter on it, its hovering between 40 - 41 V.

Thanks for speedy responses. I will dig out the multimeter (due to a recent house move its buried in a box somewhere), and let you know results. Kirstin, you are right I bought the kit from the 8Fun guys in Birmingham, hence my contacting them.

Back in january I bought the 8FUN 36V / 250W e-bike conversion kit. and to convert my bicycle to electric. At that time did not know about this forum, wish I had! Anyway it worked great for 2-3 months, but recently it stopped working. When first switched on the power light on the LED panel glows for a couple of seconds, then goes out. The battery has been fully charged, and the motor was working fine up to that point. It has been ridden in the rain quite a few times, and during the day time is not parked undercover. So possibly some water has got in? I'd be grateful for any advice on how to troubleshoot this. I have sent email to 8fun (no response) and tried the 0845 number, but no answer on that. Before trying the other numbers I thought it would be good to troubleshoot a little myself. thanks for any suggestions, Andrew
