Disconnecting the batteries

[Bobdes]

Any special order in which these should be disconnected??

Always remove the negative connection that goes to the trailer first. That will break the circuit if your wrench hits the frame when working on the other connections and prevent a short.

Remove negative first
Install positive first

I always do neg first.. Slide the ends into short lengths of rubber hose and repeat.

1) Disconnect AC power if connected.
You don't want to run the Univolt/converter/... w/o a
battery connected unless the unit is explicitly designed
to support that mode of operation.

2) Disconnect ground (black) going into the battery box.
Ground is disconnected first in case the battery box or
surrounding structure is grounded. This way, inadvertent
contact of the wrench & surrounding metal doesn't cause
problems (sparks, explosions, etc).

3) Disconnect hot (red) going into the battery box.
It's now safe to disconnect the hot lead, since the
surroundings are now electrically isolated from the
battery.

4) Disconnect cables linking the two batteries together in
either order.

Excellent info, makes sense. Thanks all.

bart,
I have just posted a question about running the converter w/o batteries connected. I jsut found that you answered this below sometime back. Do you think it would be ok to connect an old and barely serviceable battery just to keep the converter from being damaged? I maintain my abtteries on a batteryminder and I want to have a/c power on the TT to run a dehumidifier/heater.

Why not just flip the circuit breaker for the converter or unplug the converter? (Most have a normal 120v plug).
