New conversion project for Piaggio Zip 50

Pretty much all the brain stuff runs off 5v even if indirectly, and any external stuff you have like throttles, motor halls, or other sensors run from 5v provided by the controller.

So any of those things could drag 5v down. If it's a direct short, zero ohms, it's more likely to be a wiring fault than a component fault, but you'd have to open it up to test all the parts on the 5v bus to find out whihc one causes it. That requires disconnecting parts on the 5v bus until the resistance goes back to normal.

Even after you find and replace the failed part, the actual 5v supply electronics inside could be damaged and still not supply 5v until replaced.

No, it reads about 19ohm and it is shorted to ground (multimeter beeps). So I will have to disconnect all the 5v components? Could this thing have damaged other things like bluetooth module or other 5v powered? I am seriously worried.

I bought an ASI bac4000 because mine died. It was mounted on a Talaria. Do you know what the settings are for the engine I use QS 138 90H?

Ciao a tutti. Sto cercando di configurare il mio motore QS 138 90H con il controller ASI BAC4000, ma non ho le impostazioni. Nell'app Kilowatt devo inserire queste impostazioni, ma quelle con l'asterisco non so cosa siano o cosa scegliere. Qualcuno sa come aiutarmi? Vorrei anche sapere come calcolare l'induttanza del motore e come calcolare l'angolo di offset del sensore Hall. Ho anche notato che quando la batteria scende sotto i 77 V il controller non si accende. Solo con una batteria completamente carica 84 V. Da cosa potrebbe dipendere? Il motore ora è autoregolato in modalità sensorless, ma non funziona bene.
Grazie
