I thought my battery would trickle charge while driving from the tow truck with the battery off. I recently had it in for some warranty work and the service rep told me the battery disconnect had to be "on".

Let me define battery disconnect "on"/"off" as I use it:
"On" to me means the battery is making connection
"Off" to me means it is turned off and 12V isn't available except for items that are direct wired such as the propane detector.

So my question is; should it be "On" or "Off" to charge the battery as I drive?
