SAFETY
ALWAYS OBSERVE THESE SAFETY PRECAUTIONS WHEN TROUBLE
SHOOTING THE RAY MOTOR
1. BEFORE REMOVING THE TOP COVER, BE SURE KEY SWITCH IS OFF TO
AVOID POSSIBLY SHORTING TERMINALS INSIDE THE MOTOR AS A METAL TOP
IS REMOVED. STRONG ARCS CAN RESULT IN DAMAGING EQUIPMENT AND
POSSIBLY CAUSING INJURY. (IF YOU HAVE A NEWER MODEL MOTOR WITH
PLASTIC TOP, TOP MAY BE REMOVED WITHOUT TURNING THE KEY SWITCH
OFF.)
2. TO AVOID INJURY, UNPLUG POWER FROM MOTOR WHENEVER MAKING
REPAIRS INSIDE THE MOTOR COWL. SHORTS CAN BE CAUSED BY METAL
TOOLS OR LOOSE WIRES CAUSING ELECTRICAL ARCS. WHEN NECESSARY TO
TAKE VOLT METER READING WITH POWER ON, USE CAUTION! AN
EXPERIENCED MECHANIC WOULD BE A PREFERRED TECHNICIAN.
Trouble Shooting
First, keep in mind that breakdowns are few and these are usually minor and almost always
electrical. Don't suspect something catastrophic -- it rarely happens.
If, even with this guide, you are having a hard time finding the trouble, call us, and call
before you disassemble something or replace parts based on assumptions.
Give us all the symptoms and, chances are, together we can solve the problem. It may take
some tests and more calls, but we have been successful many times.
When you need a part to fix the trouble, look it up in the Parts Manual and order giving
part number and name.
The Most Likely Problems
Battery Problems
:
Batteries cause by far the most trouble, usually due to neglect, but occasionally due to
defects. Batteries may simply be discharged or a cell in one battery may be dead. One dead
cell will cause a significant slowing of the motor.
Also, terminals corrode after several years and can easily cause an open circuit. An
open at any battery terminal will cause the motor not to run and charger not to charge.
Greasing the terminals will prevent corrosion for a long time. A toothbrush and ordinary
chassis grease works well. See Trouble Shooting Chart for other battery troubles. See
Operating and Maintenance Instructions for maintenance of batteries.
