Hi all I am Keith Ellett .I am in New Zealand and I currently own a non working wisper 905 SE bike .

Please forgive me if I dont get this right first time but my excuse is I am 70 years old and are perhaps a bit out of touch with computer technology.

I have bought a wisper 905 Se bike that had a problem and came without a battery . I have purchased a later model wisper battey and charger that came without the mounting slide which also appears to contain the main terminal contacts .

My request is this .Does anyone have a circuit diagram for this bike ? It appears that the problem is in the controller and perhaps the easiest way is to buy a replacement controller as there seems to be plenty available on ebay but to be honest there are just too many wires coming out of the existing controller for me to be able to substitute a different unit. can anyone help me in this area please?

I also need to buy the battery mounting slide for the Wisper powerlong110536V 000216 battery if anyone knows where I can get one of these I would appreciate the lead. I have checked the hall effect sensors in the motor and these are all ok so the controller is the most likely culpit. a condenser had broken free inside and could have shorted other components .I fixed the condenser but the bike still does not want to respond .

Any help would be greatly appreciated
Keith
