How can I tell if my car stereo memory is bad?
you should see this in the installation manual. if you do not have the manual download it from the manufacturer or vendor website. or the unit is defective. well if your constant power wire is actually constant.. that leads only two rational thoughts. 2. the memory inside the radio is bad.
Where does the memory come from on a car stereo?
It turns out the the lower gauge wire is for the main power and the high gauge wire is used for the lower voltage memory. Doesn’t make any sense to me but now It works. it makes sense to me.. the main power can come from the yellow wire, the red wire, or both.
How to find an open circuit or shorted wire the fast easy way?
How to find an open circuit or shorted wire the FAST easy way. Also called a fox and hound tool, the tone generator and amplifier probe make finding an open circuit much faster and easier than using a continuity tester or circuit probe. Extech 40180 Loading…
What’s the difference between black and yellow wire on a car stereo?
There’s a black wire for ground, yellow wire same gauge then a red wire that is smaller than those two. It turns out the the lower gauge wire is for the main power and the high gauge wire is used for the lower voltage memory. Doesn’t make any sense to me but now It works.
What kind of metal is a memory wire?
Memory wire, a.k.a. Nitinol, a.k.a. Muscle Wire, a.k.a. Flexinol, is a nifty metal alloy (mixture) of Nickel (NI) and Titanium (TI). The NOL stands for Naval Ordinance Laboratory, where the memory properties were discovered by William J. Buehler and Fredrick Wang.
Is it possible to anneal a memory wire?
It is also possible to anneal the wire while it is looped, although it will try to straighten out at first. It is not necessary to use a pickle, for you jewelry smiths out there, although it would help to clean the wire. I chose not to, simply because I do not have the setup for that.
How to form memory wire with nitinol wire?
Connect one wire to one side of the wire, and connect the other live wire to the other side of the Nitinol wire. It will spark and get hot, but it will also move back into your shape. It would probably be a good idea to attach this setup to a resistor and a momentary switch (button) to close the circuit till you release the button (momentary part).
What’s the best way to make Memory Wire?
Once every section has been brought up to a dull red glow at least for a couple of seconds, quench the entire wire in water to cool it off. You can also quench the ends of the tweezers, as they tend to get hot enough to burn the unwary. Step 4: Don’t Burn Through the Wire! This is what happens when you get the wire too hot.
