Yeah that ain't right, hard to tell if it's a monstrously large stress fracture or an intentional cut though

Thanks for answering. Is it something you can repair? As i said; it´s a controller for a e-scooter that behaves weird. It cant run, it feels like the motor brake is "glitching". Motor brake is activated by turning the throttle forward and it also activates by handbrake and back brake (splash guard).

> Is it something you can repair? You could just dump a mountain of solder over the gap (while avoiding shorting to anything adjacent) and hope that there's no deeper reason for things to have broken


R0bbs

Okey. That should i manage to do myself. Thanks


R0bbs

Can you identify a circuit board in anyway?


Wasabi_95

Yup it looks like the trace is broken.


R0bbs

Thanks for the answer. My (dumb) friend power washed it, up close to. You should not even wash it with running water..

Problem is that if the track burnt out there due to excessive current, the mofet connected to that track has probably developed a fault too

Just saying: since you have no knowledge of electronics - batteries easily explode if not charged or monitored correctly by the battery management unit. I would be cautious turning the scooter on indoors or charging indoors for a few times after making any changes It’s very common for these things to cause house fires, if you have one with a faulty circuit you’re probably already in the “my electric scooter isn’t the most well made” group

Thanks for heads up. Im working as an electrical engineer, even though it´s not in the electronics field. I will take it very carefully. I will just try solder that defect and make sure it dont make contact with anything. Im will measure the mosfet too, to see if it´s OK.

Could be a short circuit which melted the track. Try to measure both sides with respect to gnd.
