Hi ES im from Monterey CA. I purchased a 48v 1000w battery made up of 1865 cells. I then purchased your typical rear wheel hub kit. The controller had bullet connecters for positive negative and my battery had XT90s so i cut the bullets n replaced them with an XT90. I hooked everything up to the wheel as it was on the bike frame. However i chose not to plug the PAS into controller not sure if that's good or bad. I was expecting the customary spark when i plugged battery into controller but got nothing. absolutely nothing. I want to mention the when reading description of kit when i got it the mentioned the it wouldn't run on anything less than 48v 1000w battery and also that in order to comply with California laws they made the battery capable of going from 36v to 48v by simply doing something to a blue wire. Im no tech guy at all but i get the impression perhaps the controller is assuming that my battery has and on off switch but it doesn't. Could really use some advise. Thank you.
