Why Would Vehicle Battery Still Drain After Install of BrakeBuddy Tow Vehicle Charge Kit
Updated 04/14/2021 | Published 04/13/2021 >
Question:
I have this installed on a 2018 Equinox. When connected I have 12v or more on MH side. I also show the same voltage on the car side. BUT after 4 hours of towing the Equinox battery is dead. What is happening? TKS

The Hopkins BrakeBuddy charger part # BB54FR that you referenced can provide up to a 15 amp hour charge. Now if there's a circuit on your Equinox that is active when you are towing that draws more than 15 amps you are going to see the battery eventually drain like you mentioned. Is the radio on in the Equinox or any extra circuits that don't need to be on like lighting?
