OK, a friend gave this electric scooter because it has been sitting for what he says was about 20 years but I think maybe 10 or so. Before I have to go take photos, let me tell you what I found and for starters if that is ok or not. I found two 12 volt batteries in the battery compartment ## 58A GPS-12-12-F2. and wired for 24 volts. I removed them big batteries that filled the battery tray perfectly and put them on a .5 amp trickle charger and one is almost 13 volts now and the other a little over 10 volts. I also found a plastic bag in the trunk with three heavy duty wires that were un-soldered and removed for some reason. Maybe a voltage conversion??
BUT WAIT.... The motor says 36V and I think the electronic controller says 36 volts....... What is with two 12 volt batteries then?? The wires to the EC look like a cobweb but all appear to be plugged in. I wired the two batteries in parallel ( 23 volts worth) and turned on the key and got a RED LED in the center of the two electronic gauges. Turn signal flasher beeped but no turn lights. No motor power and didn't know if there was a trick to it. BUT, I had a car battery and I added it to give me a total of 33.5 volts by my multi-meter. I turned on the key, the turn signal was crisp and well lit. No horn and LED dimmed so that was a decent sign I guess, Again no throttle response. I figured 33.5 volts should do the trick. I am going to make sure all wires are well connected after all those years but this scooter looks like new. The two 12 v. batteries and the 36 volt motor confuse me though.
My friend don't remember who worked on it and after all, he said it sat for 20 years and he forgot. I believe if a motor says 36 volts, you use 36 volts of batteries right?? I will return tomorrow with photos of what I have, etc. I guess Sunshine Scooters bought a fleet of these and had their own custom floor board mats made for it. Anyway, I know I didn't give you much but at least we can figure out a voltage solution and what batteries it should have. It appears the lights etc. are 36 volts. Do I purchase 36 volts in batteries before proceeding? Thanks, Scott
Tisamsimono.th : I suspect all wire connectors are individualized so you cannot plug one set or wires where it should be plugged.. I don't have a schematic either but IF you need a photo of something, let me know. Thanks.
I believe I may take your advice that I read on another question post and purchase a 1000 watt 36 volt motor (chain driven). 350 watts don't seem like what I need at 6' 4" and 225 lbs. for endurance. What motor and batteries do you suggest. My battery compartment measures 4" wide by 12 1/2" long. Thank-You. Scott
Also, I don't know anything about that Electronic Controller I have or I believe they are similar to the ESC controllers in radio controlled vehicles and I believe they can get burned up by too much power. Maybe I need a new one and will my wires all plug into a new one?
If any of the wire connectors on the scooter need to be changed we sell matching connectors for the controller on this page: https://electricscooterparts.com/whitewiringconnectors.html
You may want to consider installing a 24 Volt motor and controller because then the battery pack could consist of two 12V 15Ah batteries which would fit in the battery tray. We have a 24 Volt 500 Watt motor with a mounting base which is our item # MOT-24500X2500B. This motor could provide speeds of up to 20 MPH on flat ground.
Please let us know if you have any questions.
Thank-You so much for the information. I did receive a ziploc bag w/ my scooter with apparently two toasted fuses and three wires that were un-soldered and seemed to be 10 gauge maybe and I'm sure from the battery set-up. You are more familiar with what (3) un-soldered wires means in the way of how many batteries were used. My guess is originally 3 batteries maybe? After taking the photo now and looking at them, my guess IS two batteries because there is ONE wire with solder at each end which makes me think that is where the two batteries were wired in series. The other two only had solder at one end which makes me thing they were cut and spliced. I am thinking someone added the 36 volt motor and attempted to run it off 24 volts.
A friend suggested that I take a 12 volt battery, disconnect the 36v motor from the harness and use the 12 volts to test the motor to see if it even runs. He said 12 v will be enough to know if it is still good.
A friend suggested I buy an ESC and throttle kit for 36 volts. I can mount two 12 volt batteries in the battery compartment and I don't mind mounting one 12 volt battery in the trunk as it won't be used anyway. All I would need to do is run on wire for the series connection and one wire for the lead connection at the ESC down the seat post, plug the throttle into it and go. I won't need the lights or battery gauge on the handle bar console. Do you have this ESC throttle kit for the 36v set-up or is voltage a mute discussion when buying the ESC / throttle kit? Thanks for all your help.
