Thank you, Thank you,Thank you. That indeed was the trouble. As I said I'm a novice at this game, had charged the battery and checked it using a multimeter but until you explained the minus thing I wasn't savvy to this . I reversed the polarity and it now works. Again thank you.

The battery came with the kettle connector which indicated on it L, E, N and I wired the motor accordingly. I'm not sure what you mean by your last sentence what voltage do you mean. As I'm really a beginner in this field, I'm trying to suss it out.

Here's a picture of the battery concerned. It seems to charge OK, there is a fan in the charger which spins while charging and stops when complete and a green light comes on. I have also tried to measure output and that seems to be slightly above 24v. Also as the output is a female kettle outlet that's where the kettle input come in. I have access to another battery source would this harm the motor if I tested it with this.

I took your advice and bought a 24v 10ah battery from a company called Vpower . I duly charged this (was told it would charge in 2hrs, is this correct) and connected it, but nothing happened ? I had to change the connector on the bike from a two pin to a kettle type plug, to fit to the battery but apart from that, nothing else was changed. any ideas what I might be doing wrong ?

Thank you for your reply. Could I increase his this to A 36V 10ah battery or must I keep to the 24v?

Hi, I'm in need of some expert advice. I bought a Mountain Bike which had been adapted to an E-bike. It worked well at the time but over winter It's been in storage, with my caravan. Recently I tried charging it but it looks like the battery has failed. The bike is powered by a Currie motor of which I know nothing and from what I've seen, I believe the original battery is Ni-Cad ? I e-mailed Currie in USA but all they told me was originally it was powered by a 12v 12ah SLA or Sealed Lead Acid battery. Can anyone shed light on what size the motor might be and tell me if I can possibly replace the battery with a lithium battery pack,to reduce weight. Thank you.

Hi I do a bit of caravanning and like to cycle as well so last year I bought a second-hand bike from somebody on a camp site as My old legs can't work as well as they did. The reason for joining this forum is to gather knowledge, hopefully as and when I need it as I'm new to this.
