I'd roll by but I dont have wheels since the El is down for the front end rebuild. That starter was grinding and making all kinds of weird noises bruh. Then The burning smell. It sounded like the starter was having a helluva time spinning the flywheel. Since you said the starter was doin that when you got it, it makes me wonder if its even the correct starter or if its properly shimmed. Its gettin spark cuz it turns over after a lil while....I'd get a new starter bruh and clean those wires up. You dont have a single good ground on the car from what I saw. You saw how I did mine. Took care of all my starter problems. Its usually the solenoid that goes bad on em. Heat kills the solenoid quick.
