Hey. I left my cruiser too long without driving. Tried to jump start, but after a few seconds the cables became very hot and the horn blasted. 100% sure I didn't incorrectly connect the cables. I immediately disconnected the jumper cables and went to Costco for a new battery. New battery confirmed charged, but there nothing. No lights or anything. I checked the 2 large fuses on the battery cable and they appear to be okay. I'll get my multimeter tomorrow to ensure they are okay. Any ideas for the next few things to check?
