HELP:Ignition Problem 1985 GMC High Sierra

[SnowNeck]

Alright so i have a 1985 GMC high sierra, and not until recently I've been having this starting/ignition problem. so when i go to start my truck wether its been sitting over night or just a few minutes as i get gas when i go to turn the key to start it... Nothing no clicks, im getting no power. so i knew it the battery well thought anyway. i got a brand new battery and same thing. happens every time i go to start my truck. what ive been having to do is take off the Negative wire from the battery, and put it right back on and it starts. i don't get it at all, im not shacking any loose wire just taking it off and putting it right back on. i don't have any rust, corrosion, anything. I need any thoughts on what this might be, this is my daily driver so its important. thank you.

I would look real close at the condition of the negative cable.

ahhhhh then take the insulator off to see how it look maybe the wire has corosion inside next time it does that try adding a jumper cable fron the neg batt. to a braket on the engine maybe its a ground issue

Today i did all that and then some, it aint the battery, i was thinking could it be a relay? and every time i disconnect the negative i'm like restarting the circuit... I honestly dont know.

yup could be a bad battery cable end, either side
those side posts bubble and swell and get crunchy

I was under the hood and came across a bad fusible link, im thinking that might be the issue, it had a old splicing job.
