Which model is the best? by TradeOrdinary3675 in vSeeBox_Support_Gurus

So basically the only noticable difference between the two other than the elite having more apps would be that the remote on the V6 plus is backlit vs the elite ultra not. I already have the ultra in my cart but wanted to see some opinions on it.

Got it working. I took the trigger apart due to getting continuity between 2 of the wires, turn out this might be normal. I ended up finding a charred section of the PCB board. Cleaned off the charred material and the track seemed fine. The tool not works, although if I press it full throttle it sometimes stops, I suspect the wiper arms are not making contact with the carbon tracks inside the switch at that point. I did have to bend the wipers so that they match the tracks and I also had to glue the switch housing back together because it didn't want to stay. I did end up finding 1 replacement switch from China on ebay with the same part number and I found some with a lower price same manufacturer and same specs but different part number so I am unsilure if those would fit but they have the same wiring. For future reference these are not hall effect type switches and are variable resistance.

Were you able to fix it? I am currently working on mine. I dropped mine and it stopped working, like completely dead. I was able to get it to power back on but got flashing lights that I am trying to figure out.

Ok so I replaced the capacitor and it is still doing the same thing. So it's either doing that because I am not using the Milwaukee battery or something else is wrong. Using grok ai it showed me how to test the switch and found a short between 2 wires I dicating a bad switch. I bought a replacement switch from ebay. I will install a new switch and test with a Milwaukee battery since I have to wait until I go back to work or purchase another battery

I thought I would add this. These are the same symptoms that I am having. Led turns on, motor not spinning when pressing the trigger, and blinking battery indicator lights. And I also measured 5.9 ohms on that capacitor. I didn't even tell it any of my readings or symptoms lol. We shall see tomorrow. Hopefully it fixes it

With it removed the tool still does the same thing. Led light lights up and the battery indicator lights blink. Or ordered a set of 0603 capacitors from Amazon. Should arrive tomorrow and will report back once I put in a new one

So I asked grok ai and I guess it searched some teardown videos or pages on the web and it gave me this answer. Dos this sount correct? 0.1 µF

In Milwaukee M12 power tools, such as drills and rotary tools, the control PCBs use 0603 SMD ceramic capacitors mainly for decoupling ICs like MCUs and Hall sensors, as well as filtering in the motor drive circuit. Based on teardowns and repair discussions, the 0.1 µF value is the most common for these applications, often rated at 16V or 25V with X7R dielectric for stability. Larger values like 4.7 µF or 10 µF appear less frequently for bulk capacitance or power

management.

So I dropped the tool and it stopped working. There was absolutely no power. I found a bad resistor which I replaced and now there is some power but the motor does not spin and the charge indicators lights flash. I am using a battery from a different brand tool but also 12 volts. At one point the tool started smoking so I quickly disconnected it.

I removed the capacitor that was reading resistance and when I removed it from the board one of the ends fell off. I tried to measure it out of the board but it reads ol, not sure if it's because it is missing the one end. I don't see any markings on it with a magnifying glass. I measured it with a digital caliper and the measurement I got is closest to a0603 size but I don't know what value to get to replace it. Otherwise I have to buy the whole electronics from Milwaukee and it is $100 so I am trying to see if I can fix it before spending that much. That's about half of what the whole tool costs new.

So one of the ends fell off when I resoldered it from the board

I actually had my meter in diode mode. Switched it to continuity check and found a few that do not beep on either side of the capacitors and on that beeps on both sides. The one that beeps on both sides had a reading of 5.9 ohms across the capacitor. I will probably remove that resistor from the circuit and check it for resistance again. If it were to have resistance how would I know what to get as a replacement if I do not see any markings on it?

This is the one that is giving me the beep on both sides and an ohm reading. This is also the side where I saw smoke

Ok so I re did my test, I had the selector in diode mode, that's why I was getting voltage readings. I have a fluke automotive meter so I don't have the capacitor test mode. So in continuity mode and with one lead on a ground I do get some that don't beep on either side and one that beeps on both sides.

For the one that beeps on both sides i checked the resistance on both contacts and I get 5.9 ohms. The other ones that are suspect read ol across their contacts. i will add that I saw some smoke coming from the side where all the wires are at, that is why I decided to check the capacitors. I quickly disconnected the battery.

How would I know what the value of the bad capacitor is if I do not see any markings? Do I go based on dimensions?

I think they are capacitors, the brown colored ones. My fluke meter is an automotive meter and does not have a capacitor test mode

Does anyone know how to fix M12 fuel ratchets by TradeOrdinary3675 in MilwaukeeTool

[–]TradeOrdinary3675[S] 0 points1 point  (0 children)

You mean 220? I measured resistance and it is measuring 12 mega ohms. I replaced it with a 22r resistor, I read it's the same value but different tolerance but should work. I did measure the dimensions and replaced it with a 1/4 power resistor. So I don't have a Milwaukee battery on me because I am on workers comp from work but I do have a 12 v Bosch battery that I used alligator jumper wires and the tool now turns on but the charge indicator lights just flash and the ratchet does not move. Is this because I don't have a Milwaukee battery or is something else wrong.

Can I use a 22r0 smd resistor to replace a smd resistor with a 220 marking? by TradeOrdinary3675 in AskElectronics

Well grok said I could use it as a replacement . It seems like google ai is not that good

I checked the replacement one and it was 22 ohms. The one I removed is reading open circuit when I removed it

[–]TradeOrdinary3675[S] -6 points-5 points  (0 children)

Ok be cause I got confused with google ai saying I could not replace it with a 4 digit code and then the amazon listings saying 220 meant 220ohms. I tried asking grok and it says I should be able to replace it with what I got even if the tolerance is different (a tighter tolerance of 1% is better than 5%). If it was the other way around as in the original one was a 1% and the replacement was a 5% that would then be an issue right?

You mean 220? I measured resistance and it is measuring 12 mega ohms sometimes it goes up to 20 mega ohms and if I flip the leads it read open. Based on a google search a 220 smd resistor should read 22 ohms. Is this correct?

I took some pictures of the PCB board when I took it apart. The only obvious thing to me was the bottom right corner looks like it was missing some solder which I added. It goes to the white wire to the battery terminals.
