I've done the pull the fuses/relays one at a time things. I've hours with a test probe and volt meter.
The issue was the battery or more accurately the brand of battery!
As i said earlier i've changed the battery a total of 3 times in 2 years and the alternator the same, all under warranty from Autozone.
They car died again after being on the charger the day before!
I jumped it as it was raining and didn't want to ride to work on the bike. Well it gave a few weak grunts in the afternoon before it started (thank you) I just stopped at O'reilly on the way and got a new battery. I haven't used the charger in 6 weeks! the car starts every time and the headlights ( wired through relays) seem a bit brigher. I don't have to reprogram the radio anymore.
Life is good in Largo again.
Good deal, not every battery is a quality part.
I am not sure who made the battery in my 97, but it was in it when I bought the car in 2013, and I had it disconnected all winter that year due to the AC Compressor locking up, and I knew the voltage gauge would kill it (it's currently wired to the accessory circut where the original lighter was, I'll fix that one day). The next year, I didn't unplug it and it would be too weak to start the car in a month of sitting, so I bought a battery tender and that fixed that problem.
This year, the whole engine is out of the car, so I put the battery on the tender in may, and took it off in June when I started to pull the motor. It's been sitting on my work bench, and I measured it last month and it's still at 12.5VDC according to my multimeter.
I'd say that the battery is good for now.
Still not a bad idea for you if your car is going to be parked more than a week to have a battery tender. Car batteries LOVE being full, and getting a workout starting the car every day isn't bad for them, but you do have to drive them to keep them full. Luckily, I live 20 minutes from work, so my battery is always topped off by the time I get to work and again by the time I'm home. But, I have the tender hard wired to my battery, so I just pop the hood, connect it up, and it's good to go.
