Spent yesterday trying to troubleshoot the electrical system problems in my 31' 1978 International Land Yacht and need some help with respect to what might be wrong/which way to go.
*The 120V works. I have power to the outlets, the air conditioner works
*I don't have anything operating that relies on 12V
power - no interior lights, no water pump, etc.
*I hear the "hum" from the Univolt which leads me to believe that it is still operational. I plan on replacing it with an Intellipower PD 9160A + Charge Wizard which I purchased several years ago but never got around to installing.
*I have a 15 fuse + 2 battery (50 amp fuses) 12 volt
D.C. Distribution panel which is a bit of a mess. The fuse labeled "Ckt 4 Brn SFE 20" has basically broken completely off of the Panel. The prior owner wired an inline fuse for the "Ckt 5 Blue SFE 20" fuse as well as the "Ckt 2 Yel SFE 20" with the Blue using a Buss fuse and the Yellow using a blade fuse. The Yellow inline wire has also become disconnected. As I said, quite a mess.
What I am trying to determine is whether I also need to replace the Distribution Panel and if so, what type should I be looking to get? I am assuming that the Univolt is kaput since nothing 12V
is working (I would assume that if it was working at least some of the 12V
things in the trailer would be working when plugged into shore power). With a portion of the Distribution Panel literally falling apart I would think that it would also be wise to replace it too but I want to make certain that this is necessary since they run $200+ for the models that I saw that would support 15 fuses. Finally, the replacement Distribution Panels that I looked at appeared to only support 1 battery and not 2 as my current Panel does. Is this normal or are there Panels out there that support 2 batteries. Thanks for any assistance. Montanaandy
