Do the ethernet ports show any errors? Do you use ferrites on the cat5 cables?

Mikrotik Gurus please Read and give advice sorry for the length of this.
I have a tower that has been very weird for me The night before Thanksgiving we
had a huge storm. There was very little lightening but +2 of rain. At 6:00
am Thanksgiving day the whole tower crashed. I have AC run to the top, a Allen
Bradley power supply converts to dc and powers the 8 devices I have at the top
all of them Mikrotik but one UBNT. The Allen Bradley Power supply had died
Completely. I had a Climber replace the 12 Volt Allen Bradley with a 24 Volt
since all the equipment could handle the 24 volts. Everything came back up and
life was good. For 6 hours. Then the 3- RB411AH /XR2 sectors just started
rebooting over and over again. Then they went off completely but everything
else on the tower was fine. I personally climbed the tower a day later and
found that the 24V power supply was putting out 36 volts and the Over Voltage
protection on the 411's were turning them off. I replaced the Power Supply to
a 12 volt turned up to 18Volt and immediately everyth
ing was fine. For 1 week.
All the sudden one morning I got pages saying 1 of the sectors was down again
so I started watching it and It would be up for 3 min then reboot itself I
checked Routing and Watchdog all were fine, just to be sure I turned watch dog
off. Then all the sudden It stayed up. 30 min later sector 2 started going
up and down. After 15 min of that they all stabilized. They have been up for
8 days now. This morning I woke up and had one of them completely down and one
of the others have been going up and down. I was sending a tech out to reset
the tower when the Sector that had been down for 5 hours for some reason
rebooted itself and has worked ever since and just now the 2nd sector
stabilized as well.
I am going to run new wires to the Sectors and replace all the 411s and xr2s.
I am afraid this will not resolve the issue. I have already replaced the POE's
and APCs as well. All running ROS 4.11. It has been terrible weather here so I
am limping as best I can till it is safer for the climb. Any other ideas.
