Electrical Problems! HELP!
I have a 78 ford f150 with a 351m. I am unable to start my truck. I have brand new battery, a replaced the solenoid and the starter last year, and I replaced the Electronic Ignition Control Module yesterday. It still will not start. I have no power to the fuse box and no lights are working. I checked every fuse with my voltmeter and nothing. I know I have power at my battery and to my solenoid and I looked for a linkable fuse and I havent found any. My thoughts are that maybe that its my actual ignition where my key goes? Any ideas?
I did start the truck for a min and started to drive away then it died.
Thanks for any input

Check the fusible links. It sounds like one of them is burnt out. They are located in the wire loom that goes to the battery side of the starter solenoid.
The fusible links will have little "flags" on them letting you know that it's a fusible link and not a regular wire. It will say something like FUSIBLE LINK 16 ga.
If you replace them don't use regular wire, go to the parts store and get a replacement link to splice in.
An easy test is to take the link and tug on the wire. If it feels soft or it stretches when you pull on it, it's bad.

Are these fusible links sold at Orielys or Advance Auto parts? If I cant find a fusible link can I just use a fuse holder and go back with an appropriate size fuse? If so what size fuse do I need to use??
Thanks Josh

You can replace it with a fuse but I would stay with the fusible link. The links are sized by gauge, not amps like fuses.
It looks like your link has an orange flag which would be a 16 GA link like the one I posted in the picture.
I'm not sure what amp fuse would be an appropriate replacement.
