Hey Pedro!

Ultimately, you'll be looking to make sure the 4500 Series Converter # PD4575CSV has an output of 13.2 and 14.4 Volts DC (14.6V for a Lithium setup), but there are a number of steps to get to this point which you can find here - https://www.progressivedyn.com/wp-content/uploads/2017/05/PD4500-SERIES-TROUBLESHOOTING.pdf

I would copy and paste it all in this answer page, but this is directly from the Progressive Dynamics website so I'd want to make sure you're getting the info straight from them.

They do have a note at the top of their guide stating that only a qualified technician should be messing with this because of the electricity you'll be exposed to. Have you done this kind of troubleshooting before?

Thanks for the information. I did find out that the Converter was sending the voltage to the top part, and later I checked that all the reverse battery protection fuses were burned. I replaced them, and the RV regained power.
