Let's diagnose and fix a Blaupunkt esc608

[@twisteross]

Hi. I have the same scooter and on the blue and yellow wires from the 8:00 minute of the video I have a value of 5. The variable is on yellow and on blue it is still 5 or 5.01 ... I don't have a transition on the battery wires yet, as you check at the beginning by changing the probes places.. When I move the motor plug with wires blue yellow red green and black it squeaks. Either the cube or this aluminum driver squeaks. Everything is glued with some kind of glue... I did the same as you with this gas handle and by mistake I fastened the plug, probably from the display. There was a short circuit and the button on the display does not start... Something clicked when I fastened it backwards... Do you know how I can fix it or is the game not worth the candle? I had a problem with the scooter when I replaced the inner tube and since then it just didn't want to ride. Code 20 displayed and beeped, but I see that you dealt with it yourself. I hope you write back soon. Maybe replace the display and the board or what could have shorted?

Measure the wires that you shorted, measure that you do not have a short between either of the wires, measure if there is the 36volts coming from the controller to the display. If you have the 36v from the controller, the display is most probably toast

At the hall sensors, you must get the 5v intermitent between black wire and the blue, black and yellow, black and green but only when you move the wheel slightly

Solve the problem with the on/off and then we shall see

@@cristianbuga5126 replace switch button? the scooter does not turn on because of this mistake ... I do not even have spare parts for it to replace even the display and such abilities to resolder the switch ... I have the same soldering iron as you ...

@@twisteross get a pair of tweezers and short out the switch. If it powers up, it is a simple swap but I verry much doubt that. It's the last thing that could be broken. You might have the micro processor or something before it burned.
