Hello! My brand new (to me) Legacy (1999 Legacy L with the 2.2) is apparently trying to torch itself. I have had it for coming up on 2 months and have had few major problems until now. I hopped in, fired her up and drove maybe a quarter mile when I start getting a major loss of power followed by total electrical failure, then poof, nothing. I coasted into a parking spot, noticed an electrical/burning smell, and popped the hood. The starter solenoid was smoking pretty bad and melted through the positive battery cable, which was also very warm to the touch. I quickly pulled the terminal and watched for any further problems or noticeable damage.
Once it was sufficiently cool, I wrapped the damaged cable in electrical tape (temporary, just wanted to try and crank over to get it moved somewhere more convenient) and reconnected the terminal, only to have it arc pretty good and start getting warm, indicating a dead short (ignition was off, starter never cranked, power never appeared to be restored to the car). With no other noticeable shorts (I made sure the exposed portion was sealed with tape, no other melted spots were visible), I am leaning towards a catastrophically failed starter solenoid except I have never seen and rarely heard of a failure like this. I picked up a new starter and will be installing that and a new positive lead tomorrow, I just wanted to bump heads with some experts to see if anyone has encountered this before? Any ideas if this is just a symptom caused by a short somewhere else? I have found no blown fuses or fusible links anywhere and the rest of the wiring look good.
Thanks in advance!
