Yesterday, the temp reached -36 Cel. The Subaru was parked outside without starting for roughly 14 hours. This morning 4am, started with aftermarket auto starter, first shot, no problem. Warmed up 10 minutes, remotely shut it off. 1.5 hours later, tried the auto starter again, nothing, starter was cranking, but failed to start, tried a few times, gave up. Went outside, checked BAT Terminal on Alternator 11.9 volts, Battery 11.9 volts. A little low, but keep in mind, that I tried to start it 3 or 4 times in a row, eventually this will start sucking the battery. (NOTE battery AC delco 2 weeks old). Although I knew with the voltage that a car boost wasn't going to help, tried to boost, same problem, car cranks, but doesn't start. Came back inside, waited 30 minutes, finally started. I know this is not the alternator or the battery and I am starting to get the feeling that it is the afterarket starter. This only happens under severe cold temps and the Subaru For will always start on the very first shot, but will fail to start 1 hour later, then 30 minutes later will finaly start. This issue has happened 3 times in extremely harsh weather. Right now, the SUB is running in idle with the defrost, heater, fog lights and radio turned on, my BAT terminal voltage on alternator and on battery are fine. Can someone please help? Is this aftermarket autostarter killing my SUBIE?
