I do have a breakaway section of wiring installed to cover such an event. Will do a further check for the diode. RayRe: Dingy battery power wireHi Gonzo and Ductape, Thank you for your quick replies. I have new batteries in the toad and coach, if that makes a difference. I will look into the diodes but not sure if there is one that will support 20 amps. If I attach a good ground to the frame at the rear of the coach going directly to the (-) on the toad battery, should that not be enough for a good ground? At least that would match the 10 gauge wiring for the (+). There will still be the (-) in the 6 way connector also. Thank you again. RayDingy battery power wireI am a bit concerned about connecting up a battery charge wire on our CR-V. I have installed a battery line from a 2001 Chev 23 foot Class C to my 2007 Honda CR-V. The 10 gauge line from the coach (+) battery terminal, connected via a 20 amp circuit breaker, goes to the CR-V (+) battery terminal. The CR-V battery is also protected by a 20 amp circuit breaker. I have a removable section at the hitch to join both ends of this (+) wire. Note: I have installed separate brake/signal bulbs installed in the tail lamp housings on the CR-V that connect via the 6 pin trailer plug. My questions are: - do I need to install a (-) 10 gauge wire from the CR-V to the coach? If so, can I just run it from the CR-V (-) battery terminal to a clean connection on the frame at the rear of the coach or do I need to go right to the (-) battery terminal on the coach battery? - should I disconnect the power wire when the CR-V is parked for the night or for an extended time of several hours? I plan on installing the Stay-In-play DUO as the CR-V brake system. Thank you for any suggestions/help. Ray
