Tomasz Czyż Posted August 18, 2020 Share Posted August 18, 2020 Hello I have a damaged v5f. After driving onto the curb it suddenly turned off. The Cap5 capacitor and the U13 audio amplifier were damaged. The capacitor was replaced, U13 desoldered because it had a short circuit on the power supply. V5F is still dead. Resistance on the Cap5 pins 30Ω. Please help or schematic board. Quote Link to comment Share on other sites More sharing options...
StuartL Posted August 19, 2020 Share Posted August 19, 2020 It may be easiest to buy a new controller board. Once you have components going short circuit then it's possible (probable?) that they will have damaged other components too. Quote Link to comment Share on other sites More sharing options...
yuweng Posted August 19, 2020 Share Posted August 19, 2020 KS & IM is the easiest to repair, GW & VS will burnt much more components & also the pcb tracks as well bcos they don't use any fuse. i've repaired an IM for a rider friend recently, U13 probably is not the cause of short but the mosfets are. i just replace the fuse & a single mosfet & its up & running, Good Luck. Spoiler Check all the mosfets for short circuit, it could just be a single mosfet or a pair. Quote Link to comment Share on other sites More sharing options...
Tomasz Czyż Posted August 19, 2020 Author Share Posted August 19, 2020 I am afraid that everything on the power line where the capacitor is damaged is broken. My guess is that the voltage stabilizer has been damaged. Maybe I will have more time on the weekend, I will check something. A board diagram would be helpful.
