I thought what would happen if I bring my truck in to service--only to have the auto technician disconnect my batteries--and what would happen if he didn't realize it was connected to two batteries. Would he be okay just disconnecting the power from the negative main battery first and then the positive main battery (and leave the auxiliary alone)?
This is what I found while googling how to disconnect a dual battery system. It's from a Ford forum. Just wondering if this is correct.
Proper procedure for un-hooking dual batteries (both at the same time) is:
1) Disconnect the black, ground cable at Secondary Battery (LH).
2) Disconnect the black, ground cable at Primary Battery (RH).
3 Disconnect the red, positive cable at Primary Battery (RH) – then wrap insulation material around it.
4) Disconnect the red, positive cable at Secondary Battery (LH).
5) Remove old batteries and replace with new ones.
6) Reverse this procedure for hook up.
