Hey Tina. The Tekonsha Primus IQ Trailer Brake Controller item # TK90160 would not drain your battery when you're driving or pulling a trailer. It only pulls 12 volts when used, which should easily recharge while you're driving. Sounds like you've got an alternator going out or it's time to replace your battery.

Did you just start towing a trailer with your 2001 Silverado?
