I finally ditched my faithful Elantra and replaced it with a 2007 Saturn Aura XR with the nice 3.6 engine. I bought it with 40,000 miles showing and now have 47,000 on it.
No problems until it sat unused 4 days at Christmas time. I jumped in then and got nothing but solenoid hammer when trying to fire it up. Pulled the battery, which was down, btw, and got it charged and load tested. Surprisingly, the battery tested good. Uh oh. Reinstalled battery and it fired right up, of course. It then sat for 2 days, and wouldn't even kick the solenoid when I tried it again.
My question is, can a bad battery load test good? I kind of doubt that. About all that leaves that I can see is a rather substantial drain when the key is off. Too substantial to be normal. I haven't added or changed anything on the car, electrical or otherwise. It does have a insurance company tattletale on it, but that's been on for months and I couldn't imagine it drawing juice like that anyway.
I could buy a new battery, but that would be pointless if it isn't the problem. Should I get it load tested elsewhere? I don't want to disconnect the battery every time I turn it off. That solution would have worked if the problem were on the Elantra, but the Aura has an image to uphold.
Thanks for any help/advice.
