Thermostat showing low voltage and no power

“Here's my Rain Bird. It was working last week. I did some yard work near it, now I can't get power. Im almost positive that those wires were already cut. That plug was plugged in, and it does look kind of broken. I also checked a different outlet, and still no power.”source ↗

“Did I break it?”source ↗

“two circuits on separate circuit breakers have been losing power (everything connected to the line) sporadically, sometimes for hours at a time, without their circuit breakers tripping.”source ↗

“The lights in the whole house (mobile home) have been flickering on and off as well.”source ↗

“For the time being, I'm using heavy duty extension cords into those rooms, but I know in the long term this is dangerous and not a solution.”source ↗

“I have a situation where my "barn service" is semi functional.”source ↗

“When power was restored, I found that only half of my house had power: three bedrooms on the main floor and a basement bedroom and bathroom along with some of the open area of the basement were without power.”source ↗

“I had a momentary power loss in the house. The thermostat on this Trane xv80 HVAC unit is completely blank. I checked the breaker & the unit's power switch and both are ON. Anything else I can do here ?”source ↗

“My thermostat says no red wire connected (it is) and is showing Voc O.O2 V and Vin 0.02 v.”source ↗

“i was told my fuse may have blown but I don’t see a fuse anywhere.”source ↗

“What else could be causing the lack of power?”source ↗

“I've been battling this issue for months now and am at a loss.”source ↗

“The outdoor unit tries to turn on, can hear the loud sort of start noise, then about a second later it stops.”source ↗

“Power will usually return to the whole system within a couple of hours and it'll come on like normal and start cooling.”source ↗

“My AC/Furnace doesn’t kick on. Thermostat is working fine. I had a a tech look at the unit and he said he wasn’t getting any power to it. Turns out the main fuse (20 Amp) in the furnace blew. So I replaced it. The new fuse hasn’t blown, but neither my actual AC fan or the furnace fan kicks on.”source ↗

“Got in and noticed my seats and my mirrors were not in the usual spot.”source ↗

“Started driving and noticed that the truck was unlocking without touching any buttons.”source ↗

“Shortly after, my passenger side mirror started adjusting itself without touching any buttons also.”source ↗

“Parked and shortly after, it died.”source ↗

“when I park the car and turn it off the car will just die no nothing, no lights no nothing, put the key in the ignition nothing. I pop the hood just touch the positive part of the battery connector (no visual movement) and bam the lights come back on and the car starts up”source ↗

“sometimes when I back up the center console screen will flash to blue then "service back up camera" the car will shut on and off the wheel will lock and unlock and be good”source ↗

“I am really at a standstill it happens 1x a week at most or every other week, really frustrating can't pinpoint what's wrong because it doesn't always do it.”source ↗

“Yep, fuse looked good. I tried it with a brand new fuse and had no luck”source ↗

“I have a 2018 ford f150 5.0 that cuts all power to the radio, A/C, power steering and dash, when everything turns back on it throws a bunch of codes then goes away. The engine never actually shuts off. Brand new battery and alternator is good. Does this while driving and parked”source ↗
