How to test a car stereo radio without installing it at home Need a 12v adapter, multimeter, pliers Find which lead is positive and which one is ground Then look and try to see if you can achieve to test it👍🏽
Sir, thank you very much! You kept the instructions simple, and covered safety; you did an excellent presentation! I have a 1971 Plymouth Barracuda and need to test the AM radio I bought. You showed how simple a complex situation can. Thanks again!!
My stereo comes on I'm needing to figure out about the sound could someone tell me how I would hook up the speakers do I just hook up the positive n negative of the speaker wires to the spraker
Thanks so much dude! Glad you made this. I played with mine forever and never connected the accessory because I didn’t know it needed to be grouped with the positives. Did it your way off my battery and it fired up. Got me a little bit closer 🤘🏻❤
I got 0.5V reading from the constant wire and ground any ideas what this could be? Other reading with ignition wire and ground was above 12V so ground is fine
Very good video in general. To everyone else doing this please isolate the lines. You twist caps for the wires or just some electrical tape. The voltage is not dangerous to you but it only takes one wire to slip to short and damage your stuff. Also, make sure your speaker wires are all isolate and do not touch. If any of those speaker wires touch each other you can short the fuse or IC on the head unit.
Thanks for the video! Very helpful. But what do you do if there's no black wire from the harness? The bag the harness came in says "when there is no black wire present, ground radio to the vehicle chassis." Just like you, I'm testing this without a car. I'm not sure what to do here!
Find an available bolt on the chassis of your car and use it as negative, run a black wire from the black wire coming from your radio to the chassis, so connect the 12v to the hardness on your car and the black comong from the radio to the chassis on your car amd test, this is done on a car, outside idk how to, i would have to have the radio on my hands to see😬😅
@@azaelm4829 Well, the problem is that I'm just testing the radio like in the video. There is no chassis! I just have the wire harness and two connectors. So I can tie together the positive (red, yellow, etc) but can't do negative as I do not have a black wire coming from the harness.
If you find an old 12 volt DC & one of the lines has a white stripe going down it.... the one with stripe is your negative. Allows you to skip testing which is which. Just found that out cause I don't have a voltage meter. Thanks for the info, boutta test stereo now
Very good work, but is the sound intermittent or good ? and can the radio be turned on for along time in this way because I love the car radio very much at home ? and thank you again my friend 💐
@@azaelm4829 yes indeed, for some reason I have a problem with the ignition cable (red) and when the radio was attached it didn't work. So after doing your trick (mixing red and yellow), the radio now works.
@@houssemazzouz7133 im glad it did help someone in the world😊😅👍🏼, no worries, we all learn something new everyday, just like a lot of people from youtube help me
Im guessing 6v wont do the trick… and 24v is double the amount of what it can take so… idk, try the 6v, maybe it dont work properly or not enought power to turn it on… or try 24v and maybe burn the radio😄😅, careful.
@@azaelm4829 just tried it and my radio doesn't work. I was not sure if the radio was broken or some contact in the car. If your instructions are correct, my radio is broken.... That radio costs 1500€ new if its original. I was hoping that it is something else....
@@blondyka1 if you are hoping its something else then check the voltage with a multimeter coming from your adapter, if there is no voltage then try another power adapter
