It has trouble cranking in the morning but after I've driven around and the battery gets recharged it's got no trouble cranking. I have an aftermarket deck, amp, and subs with a 1.2 Farad cap that has been on for the better part of 5 months. I had the battery checked this morning at AutoZone and they said it's in perfect working condition. Any ideas as to what could be causing the problem?

I notice that my Voltage Block is reading 14.8v when the car is running. Could the alternator be overcharging? Or do I not know what I'm talking about?* EDIT- Also, It's been a progressive thing. I noticed it was having a little trouble starting the other morning and it's gotten a little worse everytime I've started it since. *this is obviously the case.

My bike did the same, wouldn't crank over in the morning, I'd jump it ride and it'd start all day. Luckily for me, I was good friends with the mechanic at the bike shop, so I talked him into letting me burrow a battery overnight, sure enough next day started right up. I hate to send you off to buy a new battery and that not fix the prob, but that's prolly where I'd start. It's always an excuse to buy a sweet Optima battery. __________________ http://www.shaunhamptondesign.com/Joe/Sigs/cool.jpg www.shaunhamptondesign.com

Is this with newer models or are the older ones shady as well? Reason I ask is I have a draw on mine also but it is an 89 lx with the 2.3. Thanks
