I would like to relocate my solar panel onto the stern pulpit (86 C25 SR/SK), so my cabin roof is free to walk on. I was considering running a lead forward to the battery from the new transom location, but I already have a "charging lead" from my 7.5 Honda O.B. in the same area. If I were to splice into my O.B. lead before it goes below deck, would I get electrical back current into the solar panel when the O.B. is running, and conversely, would the solar panel trickel charge work it's way into the O.B.alternater (doing some sort of damage to transistors or ??? in the O.B. alternater)? Is there such a thing as a "one way diode" or something that would prevent back current...or do I even need to worry about such things when running 12 volts? Thank you. Todd Frye

Yes, there is a one way diode, the solar panel regulator will limit the voltage to 14.3 volts and prevent current from flowing from the battery (or other charging source) into the panel. You will see something called "shadow protection" in the literature of the better panels. This prevents electrical backflow when the panels are in shadow or at night.

If you have your panels wired directly to the battery, and don't have a regulator/blocking diode, here is where you can get one:

8 amp charge controller, $35 I have one and it works great.

Todd, I also installed a Sieman solar panel on stern rail with a Honda CDI charger. I found the solar had ample charge for my use and disconnected the CDI. The motor has to run at a high RPM for quite a while to recharge and is over rated.The solar will do much better alone.
