Do You Need To Disconnect The Battery On A 2019 Cadillac Escalade While It Is Flat Towed

Question:

Cadillac recommends disconnecting the ground on battery before towing. If I were to install a charging line from etrailer on towed vehicle that is charged from Motor home does it negate the need for the battery disconnect unit? If the battery is disconnected, how does the supplemental brake system Air Force one get power to function?

I have a solution for you. Even if you have a charge line to your battery in the 2019 Escalade, there is a risk that the motorhome will actually drain the battery when the Escalade gets to low on power.

I recommend using the Roadmaster Automatic Battery Disconnect with Switch for Towed Vehicle w/ Supplemental Braking System # RM-766. It is going to give you the easiest disconnect, just a push of a button. When you are ready to restore power just put the button again.

You will still need the Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles - 7-Wire to 6-Wire Straight Cord
# RM-152-98146-7 to supply power to and sync your lights.
