DIY repairs and electronic parts – where do you usually source them?
-
Hi everyone,
I've been getting more interested in repairing and modifying Onewheels instead of replacing parts whenever something goes wrong.
For older boards especially, I think finding the right electronic components can sometimes be more difficult than doing the actual repair. Things like MOSFETs, voltage regulators, capacitors, connectors, sensors and other small components aren't always easy to identify or source.
I'm curious what everyone here does when repairing an older board.
Do you usually:
buy the exact replacement component?
look for an equivalent part with similar specifications?
salvage components from another board?
or simply replace the entire controller/BMS?I'm particularly interested in how you identify equivalent components when the original part is no longer available.
For DIY builders and people who have repaired older XRs or Pint/Pint X boards, what has been the hardest electronic component to find?
Would be great to hear some real-world experiences.

@lostintheether I mainly do diagnosis by substitution as I always have a working Xr bms, battery and controller, same with the Pint on hand.
Bms repairs are usually limited to replacing the small caps and little mosfets, the big power mosfets are a real pain to replace.
For me controller repairs are limited to the power mosfets, Xr wire harnesses sometimes have broke wire(s).
If you need parts id, let me or Lia know and we can probably help you. -

Mouser will be your best friend. This forum will be your best friend. It has parts, the bootup sequence and flow, and breaks down microchip and battery chip and where to source them.
When you get into the weeds, make sure you have a inline fuse because i have fried to esc due to shorts. I had one where it was a xt60 with a fuse between it just incase. The bms really does not have a known failure on paticular parts ( im on a og pint, they are tanks) and i just opted to buy a broken bms from a local seller as a donor for parts. On pint or xrbms its really easy to knock a cermaic cpacitor (the little things around the big bms chip in the middle). Ive onlt worked on pints a xr so cant say anything on the gt and up. Rest is really trial and error.
