Hi,
I'm a new forum member, and this is my first post.
The previous owner of my motorhome replaced the 6345 with a 7345. My research led me to purchase a PD9245C to replace the 7345 to better maintain the batteries and charge them quicker or more safely. However, it seems to me that if I have any other 12V load turned on, various lights, furnace (12V blower), etc. that load will reduce the current going to the batteries. My thought was that instead of completely disconnecting the 7345 from the system, I would wire it in through a toggle switch to the 12V distribution panel. This way when I'm trying to recharge the batteries as quickly as possible (like while running the generator) I can flip the switch and disconnect the 9245 from the 12V distribution panel (fuse board) and power the 12V stuff from the 7345. When I'm no longer charging the batteries, I switch it back. The 7345 would only have a ground in common with the 9245. The 12V output of 7345 and the 9245 would never be connected together since I'd use a toggle switch to switch to one or the other. The batteries would never be connected to the 7345, I'd just be using it to drive the 12V appliances/lights.
Does this make sense? Would it improve the rate of charging the batteries? Or maybe the benefit is to small to be worth the trouble of keeping them both available.
