Replacing the Power Converter
IMPORTANT: Make sure all power is disconnected before proceeding.
If you should need to replace the power converter for any reason, follow the steps below to
safely remove the converter section.
1. Remove the hot wires, neutral and ground that lead to the converter on the AC side.
2. Remove the converter output wires from the DC board, ground and positive.
3. Finally unscrew the screws that hold the metal converter plate to the plastic housing.
For factory repairs, return only the converter section. Make sure you use proper packaging to
ensure the product’s safe arrival.
Do not replace the converter section unless the following checks have been performed:
1. Use an AC voltmeter to check for the proper voltage at the 120Vac breaker that the
converter is connected to. This voltage should be between 105 and 130 volts.
2. Remove the reverse battery fuses and check the converter output from the CONVERTER
GND to the CONVERTER POS terminals on the DC board. This should be 13.6Vdc.
3. Check the reverse battery fuses. These fuses will only blow if the battery or DC output leads
were connected reversed, even for a moment. If they are blown check the polarity of the
battery connections before replacing them.
4. If the converter output is not present and there is AC to the converter, the converter is
defective.
