Help car not cranking Options

[Joshlm]

So 2 days ago I was driving my 914, was doing fine all day and then I came home and about 20min later I went to start it and nothing. It’s not cranking at all. I charged and checked the battery, it’s fine (12.7v , Under load it’s 12.2v). I tried tapping the starter solenoid and nothing. I used screwdrivers to check and when I made a contact between 2 points on the solenoid I got a buzzing sounds does this mean my starter is fine? The car did not crank, but I heard the starter operating. When I made a connection between the actual starter and the solenoid I just got sparks.

With the key on accessory mode the radio and electronic work. Recently the generator light went out but I haven’t had a chance to look at it. I checked the voltage at the solenoid and it was fine (12.7). I can’t check my earths right now because my multimeter doesn’t have the continuity option (it’s the $7 harbor freight one).

Does 72 have the under passenger seat relays? I didn’t see anything under the seat in my car. What do I need to test / check on my relays in the engine compartment? And does that yellow wire need to be connected to the solenoid? I didn’t see anywhere it would have mounted.

Thanks in advance
