No start from key.

Hey guys,have a little problim,When i go to start nothing from the key.The yellow wire at the relay with my test light it glows, when i try to start but no crank-en so we know thats fine,the brown wire does not light I think thats right?.Now when the key is on start posion and i jump at relay it sparks and the starter spins.the seat belt relay is jump.Ok were next to look. not sure if i fried the relay,but here is a little story,my bad.I had the starter cable push out of the way, I forgot about it and a few days later thought its time to check lights and things.Well the red cable got grounded 30 seconds max i smelled something and killed the power at the BAT+everything is working outer that no start at the key.
Check your bulkhead connection.
