So, I finally received some parts from diyeboard today and while most of the parts seem to be in order and the housing looks pretty good (my 3d printed ones didn’t last…), except the ESC appears to be DOA.
I’ve Verified 36V on the battery as well as on the input blobs of solder on the esc, but when I try to turn on the esc, nothing happens.
No lights, no sounds, no spark when plugging in the battery, nothing.
I can see a few solder pads that say “6s” and “7s”, neither of which are bridged; If that makes a difference.
When I connect the battery, the voltage drops to 5v, and creeps up very slowly to about 22v. Once the voltage has crept up, if the on button is pushed it starts to beep and light up (as the voltage rapidly drops back down) but then goes dark and quiet again allowing the voltage to creep back up.
If it makes a difference, this esc is the double hub motor version and appears to be the “v2” with the two layers of pcb soldered together at the corners with some pins.
This is a BRAND NEW esc that has not successfully turned on, even once. (They claim that they test parts before sending them out (to justify not having a warranty!), but I’m going to have to call “b**-****t” on that because if they had so much as plugged this esc in, they’d have seen that it wont even power up!)
Does this place have a reputation for ripping people off like this, or are the likely to fix this?
Am I missing something simple, or is this esc as it appears, doa?
Where do I even start in troubleshooting it to try and get it working? (I have a hot air station and know how to use it, but haven’t used it because I don’t want there to be any question that the board was DOA and that I didn’t do anything to destroy it.
I have a hot air station and know how to use it, but I think that a brand new out of the bubble wrap esc should at least work when its delivered. (and as such am assuming that I’m missing something or doing something wrong…)
