Can 12 Volt Circuit of Trailer 7-Way Keep Trailer Battery Topped Off  


does a seven way wiring harness charge the trailer house battery


Helpful Expert Reply:

Yes the 12 volt accessory circuit of a 7-way trailer wiring connector can keep a trailer house's battery topped off. Basically you'd run 10 gauge wire like part # 10-1-1 to the battery's positive battery post and you'd be set.
