I have yet toremovethe unit and open the beast up - tomorrow night's project:(Does anyone have any info on these beasts (maybe even aschematic).Is it worth the effort to try and repair this unit forexample,is the cut-over just a simple relay?

However, when ACisremoved the unit fails to pass the battery 12VDC through tothetrailer circuits.
