I have a 98 Convertible with 6700 miles on it. I had dead battery troubles last year and bought new Optima battery and leave it on a battery tender when getting regular use. This eliminated my troubles for several months. the car had been leech tested and showed all modules shutting down correctly and not reawakening.
But now I seem to be developing electrical gremlins. My battery tender shows a full charge, and when driving the DIC shows the alternator charging fine, but when I go to start the car, the starter solenoid clicks like a low battery but then the engine will slowly turn over and start most of the time. i can drive for 15 minutes, then after sitting for an hour, the solenoid still clicks 1st when trying to start. tonight i noticed that on regular intervals, the lights, both exterior and interior will dim for a second then go back to normal during driving. this happens at regular 5 to 10 second intervals. does this sound like voltage regulator going bad, or starter solenoid? any insight would be great!
Take the battery to auto zone to have them check it out. My optima went out too less than 3 years old. The warrenty was still good. Take your receipt too.
After testing the battery and if its good, check the battery to starter cable and insure its tight. Don't forget its electrically hot. There is also the possibility the solenoid is dying. 6700 miles on a 98, you aren't driving it enough to keep it running properly.
the thing that was really throwing me off was the dimming lights at 10 sec intervals when driving...sort of like if you had an engine miss, only an electrical "miss" instead
