Helping child get his new scooter working for Christmas

[tombenn444]

Couple dropped off this 36 volt phantom e scooter they lost the key near the to work without the key. I took out the key switch lock so it could be turned with a screwdriver then I noticed the red wire that runs to the hall sensor and the throttle is broke off. I've tried replacing it with a 48 volt model but doesn't help. I should note that the original thrall was a six wire throttle ignition switch and battery display combination I probably cooked the hall effect sensor that was in the throttle I do have a hoverboard stator with hall sensors on it and they do fit but I'm unclear as to what time into what here is the pictures of what it look like when I first took the ignition apart I took the controller apart to look at the board on the six wires are labeled 4.2 volts, ha, hb, hc, ground, a 0

Do you have a multimeter?

Yes, I'm getting 40v out of the white wire

Okay so I replaced the throttle with the zq-100 China throttle. And now it's throwing a e-006 error code. Internet says it's a low battery code. I checked all the connections everything is good the battery is fully charged I went into the p settings just to take a look and the throttle was set to 48 volts instead of 36 I changed it and now it shows me the correct battery voltage but still I'm getting the 006 code it's not doing anything so I took it apart and I noticed that a transistor looked just a little bit burnt. Not only that but the key switch does nothing as far as preventing the unit from turning on and either position it would functions the same and throws the same code even the keys out

Hi tombenn444,
I would like to help you.

What I know...

I probably cooked the hall effect sensor that was in the throttle I do have a hoverboard stator with hall sensors on it and they do fit

The hall sensor in a throttle (SS49E) is a different type and functions differently, verses a motor's hall sensor. (SS41F) So you cannot swap them.

I took the controller apart to look at the board on the six wires are labeled 4.2 volts, ha, hb, hc, ground, a 0

This would be the motor's hall sensor wiring terminations, nothing that will help your present issue.

White wire at ignition is full battery power.




What you probably already know...

This type of throttle contains both HIGH voltage and LOW voltage wiring. The two circuits can never meet.
The HIGH will power the voltage display and controller ignition or key lock circuit. (2-3 wires)
The LOW will power the throttle and include the output or signal wire. (3 wires)
The ground wire IS shared by the throttle and voltage display.

What you should know...

NEVER rely on wire COLORS for determining use or function.

A TF-100 display throttle uses communication for throttle operation. If ZQ-100 is similar, it may not be compatible.
Post a picture of the wiring terminations on the PCB. (also requested below)


What I need to know...

The original throttle's make and model. And/or on the ignition switch, what wires get switched and when. I.G. A two position or single switch? Power to the GREEN wire first, then to YELLOW and ORANGE, or all at once? Pictures of the original throttle's interior showing hall sensor's connections/wiring and displays wiring.
Controllers make and model. And/or where on the board do all the throttle's wiring land. PCB pad labels/wire colors.
Answers to any of my previous or future asked questions or requests.

Looking forward to as much information you can give me. You have been very patient, let's see if we can move things along in a positive direction!

Okay here u go. If anything is unclear just let me know and I will provide some context or more pictures

 

[tombenn444]

Here's a better view of the new throttles PCb

 

[TommyCat]

Thank you for the pictures.

What was the original throttle make and model?

Are you attaching the wires to the board?

Can I get a picture of the controller wiring where the throttle wires attach to the PCB, getting a good look at labels and wire colors.

If the original throttle was like the newest display/throttle replacement you tried. Did you get it from the same company that programmed the controller so they can communicate together?

Here is a thread that just came up discussing the issues of this type of display/throttle to controller compatibility…
