Ring unable to work with powerpack

Hi I installed the ring pro and updated the transformer to 16v 30am as reccomended. The ring starts up and charges then works for a bit and then shuts off. I did not install the power pack because the wiring in my chime box is different then what any instructions show. Pic below. I have the power pack put into bypass and plan to install it later today but I have no idea which wires I need to hook up. The person who wired the condo used 2 sets of wires for one doorbell. I believe one white wire AND one red wire are going to the transformer and one white and one red is coming from the doorbell. I do not have a second doorbell. My question is what wires do I need to put the power pack onto in order to get power to the ring. If I leave the setup default without the power pack it works for a bit then loses voltage. Please help. In the chime pic below, one red wire is hooked up to the front screw and one is hooked up the rear screw. Both white wires are tied together. It’s the only way power will get to it. If I remove either red wire the power cuts out. If I remove either white wire the power cuts out. Not sure where to stick the power pack to get the ring power. If I put it on the front screw and tie it into the white wires I lose all power. Also the pic of the transformer is old, I have a 16v 30a trans hooked up in the same setup.
