My 1987 Custom Deluxe 30 shut off while in idle, lost all power to truck, checked fuses, replaced ignition switch on dash. Has no power to unit to even attempt to crank up. Checked battery connections. Nothing has worked.

Do the headlights work? And I am confused about "the ignition switch on dash"
