Are there fuseable links on '85 bronco ii's?

i drove my truck around yesterday and parked it at night, went to start her in the morning and i had no power to anything, figured maybe i left the interior dome light on and killed the battery, tried to jump it and still had no power to anything, switched with a known good battery, still nothing. all i can think of is a bad ground, or fuseable link if theyre are any in the system...

btw terminals are clean and tight.

There should be a fuse link somewhere. It will look like a thick section of cable on a battery cable, or a piece of plastic around one with a squigly line on it.

I'd get out the test light, hook it to the neg terminal, leave the key on, and start poking the line, find the last place you have power too and go from there.

Are you sure the battery terminals are clean?

under that situation, i would say its something at the battery. are the terminals clean all the way though? the wires not broke? lack of chassis ground? i'm almost certain its something at the battery.. what type of battery terminals do you have?

may also be a damaged wire. Half broken and making contact when you disrupt it.
