Hi all thanks for having this forum. I recently purchased a Tao Tao ATE-501 48V 500 Watt scooter from a teenager (with parental supervision) Who said that she had it for 3 years, never rode it but now it didn't run and she didn't know why. She did say several times that she thought it needed to be re-wired. When I went to look at it, I brought one of those new pocket sized microprocessor based battery testers and a little Schumacher trickle charger. The batteries showed a little bit of sulphation but acceptable. I chose one of the batteries and hooked up the charger. To my surprise it charged up within 10 minutes. So, I bought it (dirt cheap BTW)
When I got it home, I was surprised to find that someone had hooked up the batteries in parallel and disconnected a few important looking wires. I think that she had received some help from her brothers who, based on their trucks were auto mechanics. Never the less, I wired the batteries in series and they seem to be taking a charge very well and keeping it. I still had these disconnected wires however, one of which was the fat red wire from the 48V positive lead of the top battery. After searching the internet for a schematic of this scooter, and not finding one, I noticed that most of the drawings I found had the fat red wire from the battery connected to the fat red wire on the controller. So I got my alligator clip leads and connected the two. Well to my surprise, I got a very big powerful spark that welded my clip lead to the terminal.
So here I am needing help to proceed further. Does this indicate that my controller is toast? BTW as you might have guessed, with the positive 48V battery terminal not connected to anything, nothing works. No horn, lights or anything else.
What's next? Any and all help and suggestions are accepted gladly. Thanks, Jim
P.S. I would like recommendations for an intelligent Pulse 48V charger (this rig didn't come with one)
