So, the rescue SSB-SRT had been making a faint whining noise after cranking and idling through warm up that had been dissappearing, to a no noise condition. I cranked it the other day and was waiting through warm up, couple minutes, the noise didn't go away. I revved it a little to see if it would dissappear and noticed a whisp of smoke coming from the edges of the hood...serious smoke...I switched off the engine and popped the hood whereby, letting the plastic smelling smoke dissipate. Worrying about electrical issues, I disconnected the battery cable. I still could not discern where the smoke was coming from. I began feeling around and noticed that the underside of the alternator was hotter than a 2 dollar pistol <stolen..RIP G.J.> ..considering that the engine only ran for maybe three minutes tops. I let it sit in the driveway and cool. Later reconnected the battery to crank it and pull it forward into the garage, I didnt go through a warm up of longer than 15 seconds, whining, I pulled it into the garage, popped the hood and disconnected the battery. The smoke was just beginning..still smelled like plastic. The belt looks fine. This alternator has been rebuilt twice and the first time it lasted 6 months. This time it lasted over a year. There are no fault lights on the dash lit. Where do I start troubleshooting this? If I run the engine to test voltage output the smoke will begin. Remove the belt and check for resistance at the alternator pulley, should spin freely? Thanks yall...Peace
