Replaced starter, when I reconnect my battery the starter motor runs
I disconnected my battery, replaced my starter, and now when I reconnect the battery the starter starts making noise, like it’s turning. The key isn’t in the ignition. It doesn’t sound like it’s engaging the flywheel or anything and the engine doesn’t start, help!!

What YEAR Ranger?
What engine?
Most likely is that you connected the battery cable on the starter motor to the wrong stud on the starter motor, there are two larger studs, battery cable goes to TOP stud and can not touch lower large stud
Lower stud is starter motor power, and if you apply 12volts motor will just spin, it won't engage the flywheel to turn engine over

RonD, The first relay to go was likely as you mentioned old and worn out, The next new one fried soon as I turned the key and ran the starter until I pulled the battery ground cable. I pulled the starter cable and the red/blue wire from the relay/solenoid. The relay starter post showed 'hot' 12V. relay closed. The red/blue wire showed hot only when the key/ign. switch was turned all the way to start. I installed another relay/solenoid. It fried soon as I turned the key to start . The starter turning the motor until I pulled the battery cable again! What's up? Mike.

It really matters because Ford changed the wiring around, and moved the high amp relay to starter motor
If you got the same brand relay both times then I would get a different brand next time
Does your starter motor look like this: https://www.ebay.com/itm/For-1983-19...%7CMake%3AFord
Or like this: https://static.cargurus.com/images/s...1600x1200.jpeg
This one is what is still used today
The high amp Starter Relay is ON the starter motor
So the fender mounted relay is NOT high amp
The battery positive cable is connected directly to top large post ON THE STARTER MOTOR
In the late 80's/early 90's there was a short cable from battery positive to fender relay, then on the SAME post a longer cable to top post on the starter motor
Then a smaller wire from OTHER large post on fender relay to the smaller post on starter motor, so a Double Relay setup
Red/blue wire on fender relay activates it, then 12v, LOW AMPS, is sent to smaller post on starter motor relay, it activates and 12v, HIGH AMPS, follows directly from Battery positive on the larger cables
So year really matters, also engine size?
