I have a 1983 ford ranger, where it won’t start I replaced to battery about a month ago an optima. It is showing 12 bolts as well, but when I turn the key to turn it over nothing happens, not even dash lights any help?

So I cleaned the battery cable and the solenoid posts like you said and I provided some pictures for you guys to see but it still has the same issueThere should be a positive battery cable to the starter relay(often called solenoid), its mounted on the inner fender, has 2 larger posts and 1 or 2 smaller posts
FIRST remove battery negative cable!!!!!
Then remove battery positive cable from the Relay/Solenoids larger post, there WILL BE several other wires with it, those wires power the dash and all the other electrics in the vehicle
So this is a very important post/connection
Clean it and all the wire ends, and put them all back on, and secure the nut
Now clean the battery negative cable end, its post should be clean if its a new battery, its a lead connector so soft metal, scrape it clean on the inside if needs be
Connect it to battery and tighten it
Remove battery positive from battery and clean it, put it back on and tighten it
Battery cables MUST BE tightened to work
The battery post cables should be on the solenoid? And I’ll check those other things as wellLooks like someone has added some inline fuses or connectors seen in 1st picture under relay
Check them
None of that is factory wiring, wires on positive battery cables terminal should be on the relays larger post with other end of battery positive cable
Batteries vent gases when charging/driving so will corrode those wire ends over time
One battery negative cable, check its other end, clean and tight

Could be ignition switch under the steering column has failed, these older ones were known to split apart, could be made to work using zip ties to hold them together
The key itself turns a gear that slides a rod inside the column, that rod slides the ignition switch into its 4 positions, ACC, OFF, RUN, START
On the big post of the solenoid? Where the other end of the battery cable is connected on the solenoid?The battery post cables should be on the solenoid? And I’ll check those other things as well

Yes, same 12volt connection to battery but away from vented gases from battery
