So i put in a in line fuse(heavy duty)..to run my Cobra c.b...and inverter if need be..to no avail..cig lighter used to work..wiring seems fine..amps seem fine for under dash fuse..i guess the actual cig lighter is toast?
Ok txs i will check that..i got a new heater core put in a while back and the a.c. unit was just left flappin in the wind..holy moly..you would think it would just slide right back in..finally got it in..haha..small victories
Well i guess its the lighter socket as i still cant get power..oh well..c.b. Will wait..got my little ghetto blaster for f.m. radio..good to hear Metallica as im tinkering
Check the fuse. As I recall, 1977 trucks actually had a fuse for cig ltr. Could also be a fusible link which will be out near the starter solenoid on the right side inner fender.
I hard wired the fuse with an updated one with a little cap on it but ya your right..other one is blown again..shoot..im ready for a shot of vodka..dont want to be to dependent on here but its sort of therapy of sorts..thanks
Either the socket is gone, something else is wired in and is causing problems or your harness has rubbed on something and worn through. The dash is steel, so provides a good ground. Sockets can be had a Can. Tire, Princess Auto or TSC cheaply. I would actually run a separate circuit for the CB and amp. Use #10 AWG wire with that inline fuse holder and keep the fuse near the battery area. Take it through near the steering/brake booster area. There should be a couple of pop-out plugs near there that should be easy to get through. My 1976 F-350 never had A/C so I don't know if you can get through that area of the fire wall easily. If you go through the steel of the fire wall, make sure you put a grommet in it. The cigarette lighter circuit wire is small and can't handle a lot of current. Useable for radio memory but not much more if you want to use the lighter circuit as intended. I really miss the '76. It was such an easy truck to work on. Side note, grease the king pins regularly. Once a month worked for me after I got them unseized and the grease passages clear again. If you get grease coming out above and below the actual I-beam at the knuckle, you'll enjoy very nice and quiet steering. Many more tips and tricks to come for the 1973-1979 trucks to come as I completely tore mine apart and put it back together. Lots of mods, as well.
Well i officially gave up..for now..soon as i put in a new fuse(underneath dash)..it blows and so does the inline fuse..oh well..i appreciate everyones expertise..but i dont have skills to tear apart and rewire truck wiring..not giving up though
The cig ltr socket is plugged in? Is the socket shorting inside? Have a look inside the hole and see if it's rotted. If so, replace it. But, it's sounding like a pinched/nicked wire shorting to the dash or some other part.
Unplug any wiring directly attached to it. Unscrew the outer shell from in the dash. The inner socket is then easily removed from the front.
