Last year i had some help rewiring my trailer running
lights and once i got the hang of it i tackled the interior
lights . Everything works fine except for the
porch light , i always blow fuses . I used #12 wire for both runs neg and pos . What would be the correct way of doing it properly . The switch is seperate from the
light , i think my problem lies with the way i wired the switch . Can someone please help me sort this out . Also what amperage of fuse do i use .
