What are 12 volt wires 30A and 30C

May 02, 2013, 11:23:26 am

When moving the battery isolator and A/C relays from outside behind the passenger side rear tires to inside under the foot of the bed, I discovered two wires connected to the start batteries at the isolator. These wires are labelled "30A" and "30C". One of the wiring diagrams shows them as "unswitched" from start batteries. I searched around the engine bay but could not find them. Does anyone know where these wires go or what they are used for?

Wyatt,

Sorry, can't answer the question, but totally agree that moving the electricals from behind the wheel to under the front of the bed in the "electrical compartment" is an excellent idea if there is room in the "electrical compartment".

Did that the second week we had our Foretravel. 

And, at least on ours, I did not need to cut or modify a single wire.  Just carefully labeled them, ran them through a hose (large enough to accommodate the largest wire plug) from under coach into "electrical compartment".  I sealed the hose from above and below,  moved the whole panel and reconnected all the wires. 

The relays, breakers, etc thanked me by never giving problems in the next 14 years of ownership. Clean and dry is good for electrical components!

I had to make the A/C fan positive wire about two feet longer.

All other wires were long enough.

I drilled several 3/4 inch or 7/8 inch holes, rather then one large hole.
