I’m hoping Wart reads this but anyone else who can explain would obviously be great. Anyway, last weekend I helped a friend instal a BEP Cluster on his 23 Persuit Walk Around. He’s running a 300 Suzuki. First, the engine rigging comes in on the starboard side then goes to a couple of terminal blocks mounted on the starboard side stringers. Next to those, there is a bus that about half + of the hots to the dash/front of the boat run to. From the terminal blocks, another 2 AWG neg. extends to the start ground and the pos extends to the engine “In” on the BEP which are both over on the port side. Next to the BEP switch there is a small fuse box with push breakers that controls the front and rear bilge pumps, the running lights and a cabin light but that’s about it. I have that fuse box wired to the house “Out” on the BEP and it actually runs through a resettable breaker first. That part is good but all of the Nav, radio, stereo, spreader etc.. doesn’t work unless the start switch is on due to it being tied to those terminal blocks & bus at the starboard stringers where the engine harness comes in. My suggestion/plan for my friend is to purchase 2 new bat cable extensions, neg. & pos and one new terminal block (both to fix the current issue and because they are long runs and are going to upgrade the extensions to 2/0 awg). We will just run a new heavier Neg to the start bat ground from the existing neg terminal block and instal a new pos terminal block next to the existing one and move the hot from the engine to that and the new 2/0 awg pos extension back up to the engine “In” at the BEP. The original pos coming off the original pos terminal block that has all the dash and windless etc going to that bus attached I will now move that over to the house “out” on the BEP. This should isolate the engine start to just the engine and get everything else on the house side. The one thing I’m not sure where to put is the windless wire which is currently on the existing pos terminal block so it’s basically wired to start bat now. When I put the new engine dedicated pos terminal block in should I add just the windless hot to it or leave it where it is and when I move that line over to the house out it will just run off of that? Sorry this is so long but I’ve tried to explain it the best I can. By the way, the previous owner installed a nice stereo system and there is also dedicated hot heavy guage down there going to the bats. I wanted to move that over to the house terminal block as well. System has a sub. Both bats are brand new and 1000 CCA. My friend doesn’t use the stereo much which is good as he really needs a bigger house bat with that thing. Thanks in advance with thoughts on this and pointing out any errors I’m making.
