I have a 1995 Defender 110 (RHD) with 300tdi and I swapped the original 65A alternator for a 100A disco alternator about two months ago. There were no issues until one morning while warming the truck up for work, I noticed the B+ wire had come loose on the alternator while it was running. I was in a hurry and, instead of turning the vehicle off and disconnecting the battery, I just reconnected the wire without thinking. The alternator sparked and the vehicle went dead and there was no longer a click or anything when I turned the key in the ignition. I disconnected the battery and got a ride to work.
After work, I checked connections of all the wires to the starter and alternator. Before connecting the battery cables, I checked their condition with no issues and confirmed the negative ground to the transfer case was clean as well. Everything seemed fine so I reconnected the battery cables, and without even turning the ignition, the engine bay started billowing thick white smoke. After spraying it down, I saw the following damage.
It's probably something really obvious but I hope someone can help me figure out the problem.
