Hi, Ive got a Maytech 4.12 VESC where the C40 Cap sparks. The error ocurs every 2nd time I turn on my board. Any Idea why this might happen? There are no signs of damage on the VESC.
Does anyone had this problem?
Thanks in advance for the help

C40 is sparking? Is C9 also sparking?
What is the voltage on the input? Does it spark when the batteries are half empty?
C40 can only do 10S, not 12S. I don’t recommend running the VESC at 12S anyway
On 10s-Liion (40V) and 6s Power supply. just the C40
Not on an actual battery? Just on a power supply?
What does the voltage measure on the input wires?
Give me 5min, I´ll check right now
Both on the 6s Charger/Power supply and input wires 25.2 V.
It´s strange… now I did not spark, even after turning it multiple times on and off.
edit: on the battery it also happens sporadically
Oh man, these are the best problems to troubleshoot
The ones you can’t induce the problem on purpose, but rather seem completely random, because we don’t know the reason yet for it.
“Intermittent faults without clear causal vector”
C9 never sparked?
no… I just checked again, now it somehow died completely. For now I think we can close this thread till I figure what got damaged.
Thanks for your help
Did you put a conformal coating on it? If so, can you post a picture of the bottle?
