Hi... I am am not able to get my Thermostat to start the AC, or HEAT or just the FAN.

I was using a lawn trimmer to clean up over grown grasses near the AC unit outside the house, and I might have stripped of a thin wire that comes out of the house and goes in the AC unit outside. This thin wire is totally stripped on couple of spots and badly eroded at few spots too. This has two thin wires, and the uninsulated wires were in contact with each other. I think that wire is known as the 24V control wire... but not too sure. I will upload the photo. The orange cable that u see in the photo is the TV cable wire. That will give u an idea how thin is this wire that looks damaged

Also I noticed that the furnace circuit breaker On the main circuit breaker panel was turned off. I did turn it on, and tried to start the AC from the thermostat. The thermostat was flashing "cool on" but the AC was not kicking in. I then tried to turn on the HEAT and just the FAN but none of them came on. I then went outside and nicely separated the stripped off UN-insulated wires and tried again, but still nothing happened.

The "Cool On " is no longer flashing on the thermostat, but it is still not able to turn on the AC or anything else.

Please advice

Thanks and with regards
