I’ve been riding the Torqboards setup i purchased from diyelectricskateborads for a month now and yesterday when i plugged in my battery (6s lipo) via XT90 to the vedder vesc @chaka i heard a small spark sound and the vesc didnot turn on.
i’ve checked visually and figured there is no damage to the vesc itself and after reading here a bit i figured i should test the votlage before and after the capacitor box, and what do you know?! the read before the capacitor is good (24 volts for my 6s 70% charged) and 0 volts after the capacitors…
This is bitter sweet since for once i was very dissapointed with my vesc faulting on me so fast but 2ndly i was happy to realize its the capacitors and that this vesc could be saved.
Question is, how to i solve this safely? can i go to an electric shop and get new capacitors of some kind and rewire them trough?
Any suggestions?
I’ll be posting the thrilling video of my issue soon
If the VESC is receiving 0 volts there may be a faulty solder joint or something on the capacitor board like a broken copper trace, the capacitors are in parallel with the battery and are only there to smooth out the voltage ripples or spikes going into the battery, so if there is something wrong with the capacitors the esc should be still getting voltage unless there is a short, which you would definitely know about! I would carefully examine the capacitor board and solder joints and check for anything wrong. I hope this helps.
i did a visual check on the capacitors, they look well in all connection point but when checking the outlet from them to the vesc there is no current passing.
Check the traces on the PCB where the caps are soldered on.
If there are any Burn marks on it, it may be the easiest to just change the complete capPCB
ive attached a one cell 3.6 battery to the output of the capacitor board and there is one blinking blue light from the vesc yet it is not recognized by the pc.
Need to send it in for repair… should be fairly easy fix. where are you located?
Take a multimeter, put it in impedance (resistance, Ohm) check the 5V to gnd and the 3.3V to gnd. while the vesc is powered off. Both voltage rail should be identified on the silkscreen near the connectors.
Well the more destructive method would be to use some flush cutters and clip each leg of U401 off… Then again, i’m not 100% sure that this is your problem.
well it is not really relevant, it for FOC purpose and had been added on the 4.12 version. So @Torqueboard probably use the 4.10BOM on 4.12 PCB, nothing to really worry about except for FOC.
I did the test you showed, the results are that i get a steady current on the c25 as you can see in the video
and when diods touch eachother they go wild and unsteady
