5 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.
