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

15 minute installation. I used this converter to fix a not 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 worrying that the converter is already defective, but troubleshooting and installing a replacement converter cartridge is easy. You will need torx socket wrenches, a #2 Phillips screwdriver, various flat head 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.
