Onan Opus?

[Fred Hulse]

Austin,
Assuming everything is still original on your SP36:
In the compartment at the right front corner of your coach you have an inverter and on the wall closest to the wheel are two 40 or 45 amp Opus battery chargers which you can plug in or unplug those chargers as you see fit.
Commonly the way to use them is to keep but one charger plugged in and use the other also when the need for more battery charging is present.
The inverter is completely separate from the chargers as a stand alone unit.
I believe your reference in the question is to the chargers and not the inverter.
