Parallax Power Supply 7300 Troubleshooting:

  1. Charging Issues

Now, the main reason why most people buy an inverter charger is to keep their batteries charged. However, there have been many complaints regarding the power supply not charging the batteries inside your motorhome. Usually, this problem is caused by issues with the power source or the batteries themselves.

To isolate the cause of this problem, you will need to check the power output from the source. A voltage measuring device like a multimeter can be helpful to find power-related issues in your devices. Check the different battery terminals and the connection points on the inverter charger itself. That should help you narrow down the cause of the charging issue.

It is not rare for the connection points to get damaged over time. So, if you have had the unit for a long time then it would be better to clean the connection points.

Make sure to remove the connection from the power source and the batteries before touching the connection points. After cleaning the connection points thoroughly, you can reconnect everything and the batteries should start charging at this point.

  1. Beeping issues

Several customers have also pointed out that the device will start beeping at random times. It can be quite annoying if you can’t get rid of this problem.
