Elec. System Check Points ??

[Clyde-2]

Where are all the major fuse check points on my 72 ? It still has the Univolt in it. Have already found the two 20amp breakers in the bathroom and the fuses inside the Univolt as well as the inline fuse next to the Univolt. Are there any others ? I haven't plugged into 110v yet as I don't want to burn the thing down until I check continuity throughout the trailer. I would however like to at least run the 12v lights but can't get juice to them. All fuses in Univolt are good. Need some trouble shooting help. Thanks. Mike

Did you check the inline fuse on the battery cable.

you should have a 12v fuse panel for all the 12v stuff in your trailer - usually located nearby the Univolt...

There should be two fuses for the 12v battery circuit in that panel - check them - if your battery is good, and the fuses are good, you should be able to power your 12v lights without plugging into shore power 110vac...

Thanks guys.....found the 2 fuses for the pos & neg batt cables. All fuses have been checked for continuity and are good. After spraying some PB blaster on connections and some sand paper, 12v stuff is working now. Not sure what I did, but it worked. 25 years tends to corrode things up.
