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.
dnmun wrote: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.

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.

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.
