The knob post on my remote gain snapped. First the knob goes missing, now this. I was loading up groceries the other day and when I put a bag (a heavy one) in the front seat, it bumped the gain and bent the post, I tried to bend it back and it snapped off. I tried getting through with MTX and they keep telling me I need to buy a new remote. I wanted them to smply give me the specs for the potentiometer (volts, resistance, etc.), and got the run around, they would only tell me I shouldn't try to fix it, jsut buy a whole new remote. That means tearing up the car to get the old one out, it's easier to get a potentiometer and wire it in. Does anyone happen to know the specs for the one I need? Radio Shack has them and so do a few of the hobby stores here, if I know what one I need, they're under $5, I can have it fixed over the weekend.
just get out some needle nose pliers and a multimeter, grab on to what ever else is left of the knob and see what the max and min resistance is.
either way you have to tear the car up, so if you can meter the pot and replace your seld the good. if not you already have it out to send back to the manufacturer.
DO NOT attempt to meter the pot while it is wired in, your reading will not be accurate as you will also measure the resistance of the wires and what ever else might be hooked up to it at the time.
Injection is nice but id rather be BLOWN!
OK, that mostly makes sense, I see what you're saying but don't I have to have a power source to get the readings? I've never had to do this, but soldering the new one in to the harness doesn't seem too hard.
You don't need power if you're just measuring resistance.

Okay, but don't I need the voltage too? I talked to the guy at Radio Shack (not that that means much) and he said I need the resistance, which I realize, but also the voltage, since each pot. has a different voltage to meet whatever requirements for a given application.
ok ok.. i understand what he is saying.
i would assume the voltage would be 12V DC, but meter it just in case.
ok this is your pot...

stick your multi meter on that and measure the resistance, for this you dont need a power supply to measure as the multimeter will do all that for you.
next, find the lead that remote pot wires up to the amp, and meter the voltage there.
