No electrical power....Nothing

on my 79 i just had the same problem. i had a mixture of problems. the first problem was i had grounding wires. i would check your wire going from your solenoid to your starter. i know that wouldnt fix the headlights but it may be part of the problem. the second thing i did was the battery wires. i took the red one that looked brand new and sliced it open only to find massive corrosion. it was eaten through even though it looked close to new. definitely check those if i were you

I have a 85 F 250 put on new alternator ran and charged great for half hour then music got really loud lights got really bright and lost everything finally got power replaced everything electrical including wire s fuseable links and a bunch is fuses but turns over power to coil nothing from coil to distributor checks the trigger wire it's good got no indicator lights when Key switched to on

I have 2005 f250 will jump over but when shut truck off no power what so ever need ideas pleas
