BENCH POWER SUPPLY - Help!

[Al Skierkiewicz]

The Radio Shack power supply is just fine for most of your experimenting. Please keep in mind that this supply may have a problem starting some motors. You might be able to power the RC and the compressor and you might be able to run the Globe motor and possibly the Fisher Price but trying to turn the Chalupa (CIM) motors might prove to be too much current. Remember that a non moving motor is in stall and that means 133 amps for the small and 96 amps for the large Chalupa motors. If you try, the power supply will shut down on high current and the reset may require a power off to restart.

As always, check the polarity of your wiring, twice, before applying power. Many of the electronic devices cannot stand a reverse voltage.
