Bucky this is awesome I didn't know you were doin a friggin go kart tutorial. I already have one and care for it but thanks on behalf of everyone that doesn't own one!
I know this thread is super old but I am trouble shooting some stuff on my maxxam 150 2R and all of these chineses karts are the same. The brake sensor is actually really simple. It is a open close circuit as in you either have complete continuity or none that is why you can bypass it by simply connecting the wires. When the brake is applied the circuit is continuous (no resistance). It does not have a direction. It should work like this - You depress the brake pedal and the pressure in the master cylinder is applied to the sensor - the circuit is then closed (allows for continuity) and electricity is able to flow and therefore electricity is allowed to get to the rear brake light but as in my case it is also a safety mechanism in that it allows electricity to other essential starting components that allow the engine to turn over. It is a safety mechanism so that someone does not jump in the Kart turn the keys and the kart all of a sudden takes off into a wall.
i have a question i have a 49fm5 kandi i believe it has a no start issue i checked all components all seems good i even bench test the solenoid and starter good i even tested the key switch good but when i trace the engaging wire yellow and red coming from key switch it goes to a relay but the relay doesnt activate at all but when i jump the relay now the cart starts do can the brake sensor be faulty not causing the relay to start since theres a green and yellow coming from it to the relay with the other yellow and red
I just bought a new master cylinder for my buggy and the sensor isn't working. I tried putting each terminal on each pole and it still doesn't work. If I put both together everything still works right. I don't want to have to keep the terminals on the same post because that keeps my light on all the time. Am I supposed to screw the switch in more to the master because the old one I have was in there pretty far, yet it didn't work either but my brakes weren't working then either.
I had the same problem. Found out the brake pedal wasnt pushing the piston in far enough. Get a multimeter and set it to DC volts. Take the negative sensor and touch ground somewhere, maybe the battery if long enough, then make sure you have the ignition key to on. This will give you 12 volts or so to the black wire connected to the sensor. Touch the red sensor of multimeter and it should be 12 volts or more. Then take the bolt off of the brake lever so you can put a long screwdriver in the master cylinder. Push it in until it cant go any further. And test the other wire. Im guessing your pedal wasnt pushing in the piston all the way to trip the sensor.
maybe you can help me I have the same setup gokart as the one in this video I was ripping it around the other day and shut it off came back and it wont turn on tested the battery and its good idk whats wrong with it it was fine like 10 min before
Will this switch function without fluid in the cylinder? I have the brake switch and trying to rule out why the motor won’t start. Is it true you can connect the wires and bypass the brakes? Thanks.
I'm confused. Connecting the wires to master cylinder powers the ABS system, what do you connect to power brake lights? If you wire the lights to those terminals they are constantly powered and thus never indicate when the brakes are being applied.
Oh wow Is there anything you not know lol why in earth are you making RU-vid videos you should be sat in some big office getting paid massive amounts of cash for your knowledge
