Air carrier technician reported they forgot to reset 2 circuit breakers for the thrust reverser while putting aircraft back in service.

Narrative

I worked on assigned Aircraft X to troubleshoot Backup Generator Blocked message. After extensive troubleshooting involving opening TR's (Thrust Reverser) and top pylon panel; we found broken wire that required harness change. We expected; it will be a turnover but 30min prior ending my shift I was asked to reconnect cannon plugs and coordinate with mechanics to put the aircraft back in service. I was done helping out my 2 other coworkers to finish up a non-routine form and then we agreed to stay to at least go back on top of the engine and reconnect cannon plugs and reassembly the panel. From here only closing of TR's [panel] was left to do. Person A asked me if everything is ready to go and I said yes. Apparently; there were 2 C/B's (Circuit Breakers) left in bay locking the TR's [panel] that Person B left pulled. I haven't seen the C/B tags with non-routine and Person C already left to work 2nd shift at the terminal. I assumed everything was ready to go as it was on my end. Cause: Miscommunication and rush to put the AC back to service. Many people involved across two shifts and improper turn over.Solution: Slow down and communicate with my avionics counterparts and not assume.
