Review on GOYSOY Protector Analyzer Indicator Accessories by Joe Gilmartin

A simple and easy to use article to protect your van's electrical system. Arrived 2 days early. Plug it into a 30A power adapter and check the indicator light at the top of the plug to make sure it's properly connected. If the power supply is not properly connected or has any problem, DO NOT use this power supply. Do this BEFORE you connect your motorhome's power cord to the yellow plug. Then you can be sure that the wiring is safe and you also have surge protection.
