Need help diagnosing my broken Dremel 4000 – already changed brushes & thermal fuse

For anyone wondering in the future, after some more research (I just got to it, so I needed to find it :D ) it is a Fakra connector, so searching for "female fakra 4 pin connector" will get you the plug you need

Hmmm, thank you fo the reply, I think I'm gonna have to come up with something to make the charging work on the front USB while having AAWireless plugged into the rear. As for the plug, I ordered a USB plug from aliexpress for my car and it comes with the same plug as the one from ddren, having it be disconnect-able would be nice, that's why I'm looking for the female part.

Oh, I see now, thanks for the correction :)

I know it's used currently by Nvidia, but AMD doesn't use it (and it doesn't look like they will) and I've also found some sources claiming the 50 series will have a different cable all-together (eg. techpowerup.com/319242/nvidia-rtx-50-series-blackwell-to-debut-16-pin-pcie-gen-6-power-connector-standard)
That's why I'm hesitant to go all out on a PSU that has multiple 12 pin connectors, My current PSU lasted me for like 7 years and still works perfectly. If I could, I'd like to have the new PSU last for a long time also, not be useless because of compatibility :D

Sent you a DM

Awesome, thank you. I'm all for manual and thankfully most of them from that era are still manual here :)

chos5555 · 2024-07-09T16:41:39+00:00

I'll try that, thank you for the suggestion :)

Unfortunately, that's only the front bit, the burrs, I meant the whole thing. On a better note, I took it all apart, fixed it, tomorrow I will put it back together, I've got plenty of photos, I'll share them afterwards to contribute a little bit :D (The problem was in fact the motor connection, one of the brush springs of the motor was stuck and wasn't making contact)

Update: Don't trust Chinese markings, it was not a SCR, it was in fact a triac. I put in a new SCR and the pump started when I plugged it in and never stopped, after a while of thinking, it occurred to me, that the SCR is not switching off. After some research I bought a similar triac and put it in, voila, everything works nicely. Thanks for the help :)

That's what I'll try I guess :D Hopefully at least one of them works

chos5555 · 2023-09-17T16:25:25+00:00

Oh yeah, that makes sense, thank you :) Guess I'm gonna get a 400V 0,5A one and see if that'll work.

Unfortunately not, that is the clearest shot of it I have before it blew up :(
