I bought a Technics SL BD22 turntable and connected the red and white stereo cables and also connected the ground wire to the GND connection of my amp. I can hear the needle touching the vinyl but the turntable wont spin. I have checked fuse in plug and the belt is fine. Can anyone help?
If everything seems ok with the power , there is usally a small microswitch that sends power to the motor when the tone arm is moved to the start of the record.
The switch might be bad or the lever that actuates it (connected to the tone arm) might be sticking. You may have to take the bottom cover off or remove the platter to see it.
Also make sure the belt is looped over the motor shaft. If the motor runs but the belt still doesnt turn, belt might be bad.

A grounding wire is just a piece of wire connected to an earth point on the deck, connecting to an earth point say on a radiator pipe. There's nothing special about this wire any old piece will do. You only need it if you get a hum noise when the turntable is connected to the amp.
hi,
Here is the wiring of the turntable RCA plug ( RCA wire will have 4 connections like red and its outer wire then White and its outer wire.). connect these as follows.
For right channel
Red wire from the turntable to the red center wire of the RCA plug
Green wire from the turntable to the outer wire with red wire of the RCA plug
For left channel
White wire from the turntable to the white center wire of the RCA plug
Blue wire from the turntable to the outer wire with White wire of the RCA plug OK
run or rap a cable around both the phones ie red & white then run it to the GND. on the mixer or amp witch ever.failing that put a new ground wire in the turntable.when you take it apart you'll see the old one just crimp a new wire on to the old one,bob's you're uncle
presuming it has "some" effect, then gnd wire itself it good. Even though there may be a gnd thumbscrew on the preamp try slipping the ground wire under a screw on the main amp or receiver that screws into metal and make sure the gnd wire is touching metal under the screw.
if that didn't help, then you may have:
>a cartridge with an open gnd internally.
>an open gnd wire from the back of the cartridge to the outer shields of the RCA connectors.
>or your neutral & hot wires of your house wiring might be reversed causing something weird.
>a low quality preamp. (it should have a seperate wall adaptor so that only low voltage dc goes near the preamp)
good luck ground issues can be tough!
