Thanks buddy! I checked my laptop adapter with my multimeter and got 0.L which means it probably has a broken wire.

How to test ampere?

Very good instructions, just what I needed.

Instructive and good. Thanks.

Gah! I had it set on AC voltage before your video set me straight. Thanks, my man. You helped me find my problem.

I thought my dads speaker died but it was just the power supply. Very, very nice to know 👍🏼

I’m literally diagnosing my Jbl extreme speaker 😂 .. never had a power adapter die in my lifetime but I think it’s a first now !

@@5abivt it's incredibly easy to throw away something that has no problem at all, knowing how to diagnose those things is something really, really good! Now I have curiosity about all the other electric things in my house 😅

@@matheo4712 indeed !! This speakers worked great and talking to the wife.. couldn’t believe that it’s been like 8 years already .. seemed like 3-4. It’s always been taken care of I usually listen to it in the garage when working on cars. I have a digital voltmeter that I wasn’t sure was reading correctly but I brought the Adapter to work and tested it and same thing.. it’s putting out like 40 milivolts so I can order up a new one. Hopefully it’s my issue too glad you got yours working ! 👍🏼

@@matheo4712 wanted to update that is was my power supply in the end ! Both batteries charge well with a new psu. I’ll be taking the Jbl one apart to see if I can find where the issue occurred ! 👍🏼👍🏼

Thanks! I needed to test a power adapter before selling and I successfully used your instructions.

Because output voltage is low
