Hello Scotty,

          My problem is I have a very high parasitic drain on my wifes Acura. It has a large spark when you connect the battery cable, so much so it leaves small arc marks on the battery terminal.  I have traced it to the main power wire going into the underhood fuse box, buy using a test light hooked in series with the negative side of the battery with the negative cable disconnected. I isolated the alternator wiring as well(disconnected the main power in and the 4 wire harness)and I still have the drain. Now I have no lights or power of any kind in the car, even after charging the battery. Interior of car is totally dead.Engine will not crank either. I have checked the main 120/70 amp fuse in the above mentioned fuse box both visually and with an ohmeter and it is good. I think I made a very small mistake when I was replacing the whole suspension  on the car I had to move the underhood fuse box, SLIGHTLY, to allow access to one of the 15 mm bolts that bolt the strut to the strut tower, under the crossover bar that ties the two strut tower together. At first after finishing the suspension install I started the car and the battery indicator came on right away. I checked it with a voltmeter and its putting out just 12 volts and steadily dropped the volts. I then noticed smoke coming from the wiring that goes into the alternator. I immediatly disconnected the battery. After checking everything I cant visually see anything wrong, bare wires touching etc. Didnt see any of that. Try to hook battery back up, and get a huge spark when the NEGATIVE cable end touched the neg. terminal. The cables got very hot, but not melting insulation, but really warm, and then you can see on voltmeter the battery is losing volts very quickly. I charged the battery back up, and then tried it again. Same result huge spark if connecting the neg battery cable to the negative side of the battery. As of now, like I said above I think there is a short inside the underhood fuse box, specifically on the main 12 volt feed coming into the box. Thats what I think. Please let me know what you think. By the way I cant find a single blown fuse.  Thank you for a great very informative youtube channel. I'm a subscriber and watch your channel, pretty much every day.
