Volvo d13 no start, no crank

Hello everyone, this is my 1st post, thank you everyone in advance.
I have a 2014 volvo d13, manual transmission, like 3 weeks ago i was trying to start it but only a clic, no crank, then i replace the starter and it start like new, 2 weeks ago, same problem, then the mechanic saw that one of the solenoid post (one of the small one) was broken, so i bought a new solenoid and still the same, i only hear a clic. I replace the 2 relays located on top of the dashboard where the fuses are, and still the same. It doesn't even start by jumping the solenoid. Is there another relay or fuse? Or maybe a bad wire? I checked the cut off switch and everything is fine there also the batery connections are very tight. I'm very frustrated with this, so pls any help with this?
Thank you so much!!!

 

Brand new, only 2 month

 

Noted. One more thing, i saw a cable from the positive post on the alternator to the starter.. I've never seen that before.. does that csble have to do something with it?
