Help! I fried my starter....nOOb....

It is possible for the starter itself to latch up like that. When much younger I took the starter apart on my 69 Dart to fix myself. I played with the internal solenoid, not understanding the wiring exactly. Put it on the car and it then worked, but wouldn't stop. Got a rebuilt one since too much snow to keep fooling outside.

No loss. You can get a nice used one for $10 or free. Most here change to a "mini-starter" from a Magnum V-8 engine since 1/2 the size and weight. After taking yours out of your small block a few times you will see why. The big beast factory starter is only convenient in a slant and even then who needs the weight?
