Battery Box Identification

October 08, 2011, 09:53:25 pm

Digging into some electrical issues today.  Took a picture.  Wish I would have backed a little further away now that I look at it to include the battery connections.  I listed two unidentified objects (one arrowed in purple, the other in white).  Anyone know what they are?  Also included my schematic to help.

Hope you are not sitting and waiting your answers, and someone with lots more knowledge can help, but maybe this will help. 

The breaker on the right might have a reset button, that you can access from the next bay area, thru a finger hole.

Sometimes I take 2 steps foreward and then 3 or 4 back as I am learning more about my systems.

Your ISOLATOR is probably located on a rear facing wall on the street side of your engine compartment, just inside the street-side access door. Next to the shore power plug.

The white arrow item on your battery box wall is just a simple insulated bolt that is used to connect multiple positive battery cables together. It acts as a splice junction.
The purple arrow item is properly identified as circuit breaker.

Or the white arrow could be a splice for battery ground cables.  Follow the big cable to your battery to see if the connector is for negative or positive.

Your wiring diagram shows your coach has a clever and practicable design for your boost solenoid that most other coaches don't have. On most coaches the dash boost switch gets power from the house OR the start battery.

If one battery bank (start or house) runs down completely, there may not be enough power to the dash boost switch to close the boost solenoid. On your coach the dash boost switch gets power from both the house AND the start battery banks and if one bank is depleted, the other will close the boost solenoid.

When I zoomed the battery box photo, I could not determine if the big splice bolt of cables was for negative or positive, so I revised my earlier comment on the white arrow.

WRT the white arrow, I was out at the coach today and got a chance to look.  Yes, its a common negative terminal.  Wonder why they used a red cable here?  I was always taught black for negative.
