I had a problem when battery didn't seem to roll the engine over fast enough to start, only one or two revolutions.&nbsp\\; It then wouldn't roll and the security system sometimes didn't arm itself and then if it did I couldn't disarm it so my I thought I had a fob problem.&nbsp\\; Change that battery and no solution.&nbsp\\; Also the engine light wouldn't come on so the service manager said to switch the run/off switch a few times with ignition off, no luck, else bring it in.&nbsp\\; After thinking about it for a couple hours I thought I would check the ignition fuse and that was it.&nbsp\\;
&nbsp\\;
I usually always hook up a battery tender plus so the problem didn't surface again til I didn't do it and then same thing.&nbsp\\; What could be wrong since the battery takes a full charge?&nbsp\\; I finally check my cables and they were snug but not tight.&nbsp\\; Two days without the battery charger on and the problem seems to be solved.&nbsp\\;

 

Those battery cables will get you every time.
