Hello, I have a 2015 dodge dart with 53k miles. I've been having issued with the car starting. One day the car was starting fine and the next day it wouldn't and then it struggles to start like if it has a weak battery. I had to get the car jumped in order for it to start. I went to Oreilly to have the battery and alternator checked and both are in good condition. I have looked into this matter in other forums with people with similar issues but I have yet to find a solution. Can it be a bad starter? Electrical issues?
First thing: Check all electrical connections: battery posts, alternator connections, all ground connections. Check all wiring for damage. Clean connections. Tighten bolts. See if that helps.
F.S.
Also if possible do a voltage drop test across the heavy cable going from the battery to the starter to see if you're losing power there.

Another thing you can try is a load test on the starter.
