Tips and tricks

Tow vehicle circuit tester

A modern RV has many electrical circuits, both 12vdc and 240vac. With the low voltage circuits often a problem can be difficult to correct until you first identify exactly which circuit has the problem. Here I have constructed a simple testing device. Note...this test only relates to the 12vdc systems, never the 240vac systems. I ALWAYS ensure the RV is disconneted from the shore current (240v)  before doing anything with the electric systems. 240v systems in an RV can only be serviced or modified by a licensed electrician.
