12v is actually a bit low. 12.1V is a 50% charge. Put a charger on it for a half day Just check it when you do get it running and needs to be 13.5 to 14.5V Even when not running. Check your cables, all four ends, 2 on Red+ cable, battery and starter solenoid, ground, battery and follow it wherever it leads, probably block and make sure is clean and tight.
