Cassette player: tape runs too fast
Bryce F Sullivan
it should. The songs don't sound like the Chimpmunks, but
they are too fast. Would this be a belt problem or something
else? What might be the fix for this? The system is an AM/FM
radio with cassette player in a 1988 Seville.
Thanks for the help.

Actually, I don't think that it is anything internal to the radio /
tape deck. I suspect that the alternator may be overcharging
resulting in excessive voltage being supplied to the unit. Check your
charging voltage with a meter, it should be 13.8v-14.8v.

Bryce,
Clean the the entire area where the tape meets the transport.
The correct speed is friction dependent, and you may have a piece of
broken tape, or something, lowering the friction drag.

It could also be a problem with the voltage regulator that supplies voltage to
the capstan motor.

A lot of time (in fact most of the time) tape decks will have an internal
'pot' where you can adjust things like tape speed, left/right level
adjustments, etc. You need a schematic to find the proper pot however
unless it is clearly labeled and it does require you to open the deck up.

All cassette players have a voltage regulator that keeps the output
voltage stable if the input voltage varies between a certain range.
Between the voltage regulator and the input to the motor for the cassette
player there should be a small pot with a slit in the middle so that it
can be turned with a small flat head screwdriver. By tuning this pot you
can increase or decrease the voltage to the motor of the unit and
therefore increase or decrease its speed. Since these pots are
factory set the speed should not change if the cassette player was not
taken apart. I would check the charging system first. The voltage
regulator can handle a fair amount of play in the input voltage level
but if the charging system is really out of wack this would cause your
increase in speed. If there is nothing wrong with the charging system
simply adjust this pot until you get the right speed.

motor faster. (Tape-players nowadays should have an internal voltage
regulator to compensate for voltage fluctuations.) Does it do the same
thing with the engine off?

Be sure you check the capstan for accumulated dirt, old tapes, etc. If
the capstan has a layer of anything on it, the tape speed will be too
high. The capstan is the shaft on the motor which moves the tape.
