Review on Parallax Power Supply Replacement Power Center Lower Section (081-7155-000) - Enhancing SEO-friendly Product Title by Justin Metz

Installation 15 minutes. I used this converter to fix a non-charging Parallax 7155 switchboard. Disconnect the negative cables from the bus and chassis batteries. Disconnect shore power and ensure the generator is off. I completely replaced the 7155 panel about 4 years ago. It's a little concerning that the converter has already failed, but troubleshooting and installing a replacement converter tray is easy. You will need Torx socket wrenches, a #2 Phillips screwdriver, various flathead screwdrivers, and allen wrenches. You should also have and be able to use a multimeter. The connections in the control cabinet must be clean and tight. Batteries should be in good condition, connections clean and I have fully charged them before turning on the new converter.
