WARNING
High voltage is used in the operation of equipment. Do not be misled by the term LOW VOLTAGE.
Potentials as low as 50 volts may cause death.
Remove rings, bracelets, wristwatches, and neck chains before working around the locomotive.
Jewelry can catch on equipment and cause injury, or may short across an electrical circuit and cause
severe burns or electrical shock.
NOTE
All resistors in the locomotive, excluding the battery charger resistor, will be removed and installed in a
manner similar to the headlight resistors.
