I owe my boyfriend a steak dinner and I don’t mind paying, but I want to understand where I went wrong. We were going out and the car wouldn’t start. It had been sitting in the driveway for 30 minutes with the engine running to keep the AC on while we waited for BF. My friend and I were inside but her teen-aged daughter was in the car with the engine running and the AC/radio on. The kid says she turned the engine off and left the ac and radio running no more than 10 minutes before BF arrived. (I believe her because it was hot and she would have noticed if the AC stopped blowing cold air.)
But when we turned the key, dead silence. After much poking and prodding and banging on what I thought might be the starter, with everyone else saying we should just jump-start it already, I proclaimed I was 100% sure it wasn’t the battery and would spring for the steak dinner if it was, because the engine hadn’t even coughed, yet the lights, AC, radio, etc. all came on. (We turned them off when trying to start it, of course.)
I figured that if the battery had enough juice to run the accessories, then it should have at least given the engine a small turn – and I didn’t think it was possible for the accessories to drain it in 10 minutes in hot weather. But BF insisted on jumpstarting it and it fired right up. Grrrr. It’s a ’98 Subaru Outback. Battery not terribly new, but it has started reliably all week since this happened. What am I missing?
