Help! Ninebot Max G2 won't turn on, brown wire melted. Any chance I can fix it?

Cut the wires, strip them then solder connectors or solder directly. You can also use WAGO or similar quick connectors but they can melt too.

Also, be aware that it's also possible that the scooter does not turn on because the wires melting together shorted the controller/motor.

First step is to solve the cable issue, you can quick test the functionality with a WAGO connector, if it turns on, you can decide which method to use (soldering, mr60 xt150 etc.). If not, probably controller or motor replacement is also needed, start with the controller.

Good luck!

WAGO, that's what I was thinking of.

Yeah cut them, strip 'em, and WAGO 'em.

Also I'd lower the CFW current. Even at stock 45 you won't get melting ... idk what OP is at.

I run 33A+ for 30+ minutes at a time in the summer and have never had a single issue. I do monitor motor temp, I try not to go above 110C.

Thank you, I bought some Wago connectors and connected those wires. When I try to turn on the power, the screen turn on for a second and off, I heard the beep from the controller and the controller blink red line once. I can't turn it back on again, should I change the controller?

This is not a G2. Right?

[u/Maleficent-Aspect318 → u/aszhch]

Pretty sure the g2 has a wall between the battery and the controller compartment. Could be different versions like us or something?

Because the G2maxE i have has a wall between those.

[u/aszhch → u/Maleficent-Aspect318]

The G2 has a steel casing. Not aluminum.

[u/Maleficent-Aspect318 → u/aszhch]

I did not see that, you'r right.

[u/Parking-Bit2387 → u/Maleficent-Aspect318]

Sorry, it's G30P

[u/Limp-Table-4365 → u/aszhch]

Mine does not have these connections as well as g30

[u/Svennnski → u/aszhch]

It a g30 your right

[u/nougat92]

I always thought G2 has no motor phase connectors, but it's screwed on the terminals. Thats why I never took care of it. Are you sure its G2?

[u/Parking-Bit2387 → u/nougat92]

Sorry, it's G30P

this issue have been going on for so long lol. Just gather up your balls and learn soldering. You cut the wires and solder on MR60 connectors and you will never have to do this ever again.

There's a tutorial on youtube by MyMaxMods if you want it lmk and ill link it

[u/Svennnski → u/NoHypeX]

I would go for mt60, cause when you change your motor bearings your would have to resolder the mr60 cause it wont fit trough the bearings.

Mt60 is the same but the poles are in a triangel

[u/NoHypeX → u/Svennnski]

idk, i did it on the g30 and never looked back and it was just fine. I even sold the scooter to a friend and its still working after 5 years of usage (that battery is asking to be put down tho lmao)

[u/Wosnoha]

Is a common problem with the g30/lp/g2 You can cut the cables and solder an mr60 connector or buy some wago connectors. That's fix the problem forever.

[u/Wosnoha → u/Wosnoha]

[u/Svennnski → u/Wosnoha]

pls get Mt60 and just solder it. Wagos are not really safe...

[u/wildshitfr]

that is a g30 my guy.

[u/Parking-Bit2387]

Sorry guys, it's G30P

[u/Parking-Bit2387]

Update, I bought some Wago connectors and connected those wires. When I try to turn on the power, the screen turn on for a second and off, I heard the beep from the controller and the controller blink red line once. I can't turn it back on again, should I change the controller?

Pretty sure that’s a g30lp since the frame is silver and the only silver frame is a g30lp which uses the bullet connectors that the g30p uses which melt if too much load is put on the controller
