you did fix whatever short you had that killed it in the first place right? Also what setup are you using? Is it the Banzai adapter or do you have the ap engineering unit ?
The ticking can be several things, esp if you have an electronic boost controller you will hear a ticking noise coming from it with the power on to it.

 

There are 1000's of people running the PFC that have never fried one. If you did not figure out what shorted it out the first time, it was just going to fry again, which it sounds like it did.

There are four major grounds (4A, 4B, 4C, & 4D) if you have voltage backfeeding into any of these it will cook the PFC and you will get a "Connection Error"
