A few months ago I purchased a servo turntable from a charity shop for a few pounds, bought a 12V adapter off eBay and used paperclips to connect the adapter plug to the servo plug, and that worked perfectly and still works great to this day. However, I've now bought another turntable from eBay with its cable cut and figured it'd be the same, and it was when I tried the same method using the paperclips, but I decided I wanted to solder the 12V adapter to the inside of the turntable.
So I removed the cover and stripped out the cord that had been cut (paying attention to the positive and negative orientation). I then soldered the red and black cable to the corresponding cables within the turntable (which are blue and orange). I plugged it in and moved the tonearm across and it now spins very quickly in reverse, and the speed does not change regardless of whether 45 or 33RPM is selected. When reject is pushed it makes a clicking noise.
I looked on some other forums and it was said that spinning the turntable forward by hand before plugging it in would help, but I tried that and it didn't work. I also tried adjusting the speed screws on the motor, but to no avail.
I know it's something I've done as when using paperclips the unit worked perfectly well, and the power adapter I'm using is definately the correct voltage (the back of the unit says 11-13V and it's 12V).
Does anyone know what's wrong with it? I thought I might have the positive and negative the wrong way around but don't want to switch them in case I totally destroy it.
