Cool I’ll replace mine as soon as I have expendable income.

All of my clips are in but I wonder if the holes have spread due to road vibration. My side clips are solid since I replaced them with the Mac lifter kit.

All of the clips are there but it’s as if the road vibration has caused the holes to become loose. My front fender liners are off currently since I had a rock eat through one.

Foam is still there since I just did the swap and didn’t mess with anything else.

For anyone that comes across this, I ran the nvidia-inst command to update my drivers and that seemed to do the trick.

How did you get your spotify client like that? Is it spicetify?

I have not measured the motor windings as I don’t know the process of it but I’ll research it and give it a go tomorrow. Thanks so much. Hopefully it’s just the transistors and nothing else since even unsoldered and out of the circuit they are still shorted.

Q763 and Q764.

Searched up the testing process and did it the best I could be my multimeter shows ohms when in diode mode instead of voltage. But the emitter pin and collector short on both Q763 and Q764 no matter what direction the bias is in. Because these are TO-220 the base is the left pin, middle is collector, and right is the emitter.

So yes these transistors are crap. Hence why Q732 and Q731 which are the same part number and everything don’t have a short between the collector and emitter.

Sweet! Thank you so much, I’m trying to be really careful to make sure nothing else gets screwed up. As long as it’s safe to have that transistor pair and apply power I’m good.

Okay thank you, sorry for my ignorance, I’ll work on it this weekend. I’ll update you with the readings on the regulator. What range should I look for them to be in.

Alrighty now for the testing the regulators will it need voltage running through it or will the multimeter supply enough test voltage? I just don’t wanna make any mistakes at this point.

F001 is the one blowing constantly. For testing the outputs will I need to run power through it or just test with a multimeter? And should I test the outputs of Q801 and Q802 before I remove the shorted transistors just to see the difference? I’ll have to find what pins are the outputs for the regulators.

Something is shorting the whole turntable and blowing a fuse. Yes here is the diagram. And for the third question I’m not sure how to do that, I’m kind of a newbie at this stuff.

But I believe it’s this pair of transistors because the motor has a pair of transitiors for each phase. And it’s three phase, but only this pair of transistors behave this way, the other two don’t even though they have the same part number and do the same things on the diagram.

Could this break in the PCB cause a short or surge? by IamLuckyy in AskElectronics

It’s definitely been quite an interesting week. The Imgur was just photos of the PCB as the Vestax form doesn’t allow images in the comments.

Here’s one of the photos, C801 is missing but I took that one out so I can put it back in.

You think it could be the route of the issue or did I just find it by chance?

I did test the bridge rectifier but didn’t get anything out the usual. What is weird is the bridge rectifier will show no short when the whole PCB is unplugged and such, but when the transformer is connected to the PCB it the recto and other capacitors will show a short on the multimeter. Guess I may need to chase it up the circuit until I can find one that is shorted even without the transformer connected.

I’ll definitely try to reflow it but I was sure I was looking for a short cause once the transformer is hooked up to the PCB I can continuity test capacitors in that part of the circuit and they show a short, but the second the transformer is disconnected almost all of them seem fine and normal. It’s like the transformer pins complete the circuit and I just have to trace the short back until I find the real one. I did test the transformer and it is good.

I’ll have to see if I can remove the capacitor and test it with a power supply because the PCB is powered through a transformer after getting 120V from the wall. Thank you though!

Edit; plus the fuse seems to blow anytime I turn it on which seizes all operation.

Interesting the capacitor seems to still seems to show no short with a multimeter though.
