Troubleshooting
Chapter 5 will help you identify the source of most problems that can
occur with the inverter.
If you have a problem with the inverter, please review this chapter before
contacting place of purchase.
If you are unable to solve a problem and need to contact place of
purchase, record the information in the form “Information About Your
System” on page WA–6.
Common Problems
Buzz in Audio Equipment
Some inexpensive stereo systems may emit a buzzing noise from their
loudspeakers when operated from the inverter. This occurs because the
power supply in the audio system does not adequately filter the modified
sine wave produced by the inverter. The only solution is to use a sound
system that has a higher quality power supply.
Television Reception
When the inverter is operating, it can interfere with television reception
on some channels. If interference occurs, try the following:
1. Make sure that the chassis ground screw on the rear of the inverter is
solidly connected to the ground system of your vehicle.
2. Make sure that the television antenna provides an adequate (“snow-
free”) signal, and that you are using good quality cable between the
antenna and the television.
3. Keep the cables between the battery and the inverter as short as
possible, and twist them together with two to three twists per foot.
(This minimizes radiated interference from the cables.)
4. Move the television as far away from the inverter as possible.
5. Do not operate high power loads with the inverter while the television
is on.
