Extreme 500 not working , no matter what :( !

[tune345]

i opened it now i don't know what to do ... anyone ?

[tune345]

oh myyyyy heavenly God ... the lights came to life oh my oh my .....was trying to do this from past one month..... throttle is good but i already ordered another one ..

ok if anyone now can just help me to fix it back because there are small parts am having hard time figuring it out

[tune345]

ok i am officially going to die if this thing harasses me... it almost came to life then it does not work

2 things happened ...they are as follow

1. after opening the throttle.. i attached everything ... 2 lights came up as they should in a regular scooter.. one for DC and another for FULL( for battery) then i somehow manage to fix it back is some weird order which i don't believe is the right way... and i took a deep breath and prayed and then throttle slowly hoping motor will move but ....it did not

2. now only DC power light on the throttle... the full battery light does not

i need exact step to step method of how to fix this thing because m completing noob at this..and why did not the motor moved when i throttle , was it because i fixed it wrong

HELP !!!!!!!!!!!!!!!!!!

[tune345]

now no lights turn on

[tune345]

all the lights are turned on now ... but when i throttle it does not run

[tune345]

sorry guys for the multiple posts but.. i am so excited and confused at the same time...

here are some of the pics of my setting of my wires..if you see anything wrong..... , all the lights are running now .. power switch is on.. throttle lights are on.. 2 lights dc power and full battery power light... after banging the throttle with a hammer ... only then it started working

congrats. does your throttle now run the motor or is it still dead?

the DC indicator is just to indicate that the controller is on?

could you see the hall sensor when you had it open and how the magnet on the twist part moves closer and then past and then farther away? you can usually see where the magnet is supposed to be when it falls off.

the other trick to establish that the throttle is not working is to replace the hall signal from the throttle with a 3V battery and the battery voltage input on the throttle hall lead will cause the motor to spin up.

dc and battery full lights are on but it does not run when i throttle it.

oh okay !

i did saw the hall sensor, i took it out then cleaned the area and put it back again...there are 2 small magnets ...so when i close/fix the throttle these magnets surrounds the small hall sensor..... (magnet-hall sensor- magnet) ...

i didn't get the 3v battery thing...hall signal meaning the green wire right... and i want to know why is it still not running..


anyways ordered a new throttle .. will arrive at Wednesday probably...finger crossed

[dnmun]

the hall sensor returns voltage to the controller on the green wire. if you replace that hall signal with a 3V battery then the motor will run, which clues you that the hall signal from the throttle is not present.

you can go diagnose the hall sensor now if you wanna start learning to debug stuff.

go look at the data sheet for the SS495 hall sensor i posted up. find the 5V leg and the ground leg from the schematic. 5V is left, ground is center, output is right leg looking at the sensor from the front. then go look on the pcb for the location of those legs on the little pcb that holds the hall sensor. if there is not 5V on the little pcb where the hall sensor is soldered in then the problem with the throttle may be in the connection from where the 5V comes into the throttle and the 5V leg of the hall sensor. that would prevent the hall sensor from working. likewise if the ground is not present at the hall sensor then it would not work either, but maybe would fail with WOT in that case too.

anyway, it gives you a chance to start learning what the thing does, and you can follow the other traces for the DC indicator and 48V led too. that's how you learn stuff, just trying to figure out where the connections go and what they connect to. takes the anxiety off being a novice if you feel like you are wading in the swamp like everybody else.

Thank you so much for the detailed information.. i will consider taking and look over it. But to be honest, i am kind of noob so this is all new for me but looks interesting ... but as for now.. i really want to make this thing work by hook or crook

[dnmun]

you gotta start somewhere. it is as good a place as anywhere to look close enuff to kinda see how the circuits are laid out on the pcb. you even get curious about why some part is connected to something when you just learn about it, and it goes on and on.

i wasted half an afternoon the other day just looking at the different BMSs i have here to see if i could figure out how the headway BMS HVC worked.

[tune345]

yes i will but this categories has its owe vocabulary which i am not even familiar with so this is going to be hard..

looks like you are into these things...

[tune345]

Viollllaaaaaaa Its workinf .....but i think i blew the throttle again... its not working anymore ...


so i received a new throttle today, i installed it , it was working perfectly ... unlike the old throttle. But stupid of me i wanted to find out if my old controller was in good condition or not so i attached the new throttle to the old controller.. nothing worked i am ok no big deal . i have everything now to ride my scooter ...then i connect it back to my new controller.. and .... this is so depressing..


just shipped the new throttle back..will order a new one.. guess i will have no luck in riding this scooter in this summer ..

what could have happened ? .. i changed some wires in the throttle because it did not matched the colors ? ... is it because of that ?

[tune345]

?

[dnmun]

i don't really follow what you did. but if you put the 48V on the hall sensor lead it will damage it.

you can just replace the hall sensor in the throttle with new one. it is cheaper than shipping the old throttle back. plus there was nothing wrong with it so they may not give you credit since you broke it.

i already shipped back the new throttle which i blew up..but what kind of hall sensor do i need... because i am having a hard time finding it.. can you give me some link or something.. thanks for the help again

[dnmun]

yes, the ratiometric hall sensor is a honeywell SS495A. you can find one with free shipping here, most of these are allegro A1302s but should be the same:

here is the pdf for the A1302, note that the Vcc is your 5V and the Vout is the throttle signal back to the controller.

[tune345]

ITS RUNNING GREAT NOW .. new throttle did the job done.. but still confused does the old controller works or not , i did attached the new throttle with the old controller and then it never got started so had to order a new throttle.

anyways , just wanted to say Thank You guys so much for your time to help me out , appreciate !

have a great day !

QUESTION :

everything is running fine but after 1 or 2 minutes the scooters loses its torque, the pickup become very less powerful. i believe batteries are gone but its will too much to invest since each battery cost around 50 bucks x 4 = $200 its not worth it.

any other solution , battery refresh or any alternate source of power, this will a stupid question but how about i go to junkyard and buy a used car battery ?

[heathyoung]

A lot of people use LiPo batteries, if you were closer I could flick you some SLA's to suit.

4 X $50 isn't dear for batteries, trust me. Even some of DrBass'es Konion packs would probably sort you out, lots of work but cheap...

You've had some bad luck with this thing hav'nt you.

oh i see ..... just don't mention how much trouble this scooter gave me. i once took to my friend's house , i accidentally turned it on while on full throttle, it went into the freaking wall creating a big hole ...

but how much volt does a car battery has ? may be i can find a spare battery from junkyard ? , i think its doable.

[tune345]

1.what are the maximum performance batteries i can install for extreme scooter x-500?

2. i looked up max is 12 volts but the AH increases , which greatest AH can i install for my scooter keeping in mind the dimensions of the batteries.

3. Any cheaper 48 volts batteries packs?


i did my research i just want to find out what you guys think ?

You might want to post the results of your research so people can see what you already found and know, to save some effort and time. They might simply be able to agree or show you why what you found is or isn't suitable.
