Possible battery/electrical issue...
Hey guys, need some expert advice.
I am the proud owner of an '84 Porsche 944, base model, no turbo and no synthetic oil.
Recently, the car up and died. No warning signs and it has been through the proper maintenance (oil changes, belts, etc.).
Step by step I am going to list what I've already tried with the car and what I've been through with the parts stores I've seen.
First and foremost, note that I am getting battery power. When I turn the key all of my dash, stereo, and exterior lights work just fine. However, the car won't start.
Next tried bypassing the starter. Didn't work the first time, nor the second, then I recharged the battery and tried again. Got it to start up beautifully. Listened for any engine issues or weird sounds and let it run for a minute before turning it off to try again.
After that, bypassing the starter wouldn't work. Took the starter in for testing at O'Reilly's, they said it tested fine and had no issues. Recommended I replace the master solenoid cylinder. This part doesn't exist in my car. O'Reilly's can suck it.
I put the starter back in, took out the battery, and brought that in for testing. Battery is only about 6mo old, and it tested bad. I purchased that at Autozone, so I'm taking that back ASAP to get my warranty.
The endgame question here is... If it isn't my battery, isn't my starter, and isn't my engine, then what's the deal? I would think it wouldn't be my alternator because I should at least see some kind of light flickering or electrical issue.
If my battery is bad, can I still expect to be seeing full lighting and stereo power?
All very strange. Any help is appreciated.

The battery doesn't really have a substantial load on it with lights or stereo. The starter is the most significant load item on the battery and if the battery is defective (fails "load test") then it's possible you would see the other items. If the new battery doesn't do it, check the ground lug (clean and secure) from the battery on the top of the bell housing.
