Title: No DC Power To Inverter
Post by: mikerobley on May 27, 2018, 06:54:13 PM

I have a 2005 Monterey Laguna that had a inverter fire. I have replaced the inverter and now I have no DC Voltage at the inverter. Can someone help me with this issue?

I would be checking for a blown fuse.  On mine they are in the small compartment above the batteries.   Good luck.

Thank you I will check them in the morning. I still have 12 volt to the T-stats, the Refer and anything else that requires 12 volt. Is there a specific one I should check for inverter power?

Mike,
There is a 3 or 4 AWG cable that runs from the house batteries through a connection just below the large 60 / 200A fuses in the rear electrical box and then to the inverter. Verify you have 12v on that cable at the inverter. If so, the problem is probably the inverter. If not check for a problem between the house batteries and the inverter.
A diagram is located in the 05 Marquis Wiring diagrams located in Coach Assist on the Private Members Only board.   http://beaveramb.org/Data/PDF%20Manuals/2005%20Monterey.zip

I would like to thank you for the advise. I had a 300 AMP fuse blown. Xantrex came through and replaced the inverter, new control panel and AGS panel for free. :)
