Battery Switch

I decided to add a dedicated starting battery to Hush, our PSC 34. Part of the modification included an automatic charge relay and new battery switch to replace the old Perko switch in the companion way. The switch is from Blue Sea.

Anyway, I was trying to install the new switch in the old switch's place and quickly found out that with the added 1/0 cable for the starting battery, there was no way to mount the switch as previously done by PSC. I had to think quick on my feet and decided to move the switch to the engine compartment just aft of the ice box drain pump.

So far I think this is going to work really well. Are there any other PSC 34 owners who have moved the switch location out there. Have you been successful in your modification. If so I would love to hear from you.

I have replaced all of the cable related to the battery with new tinned cable, which I was surprised to see was not the factory installed method. The wires I pulled were simply copper strand. Which had started to deteriorate.

Aside from having a dedicated house battery and a dedicated starting battery, I did this to prevent the electronic shutdown that usually occurred anytime I started the iron genoa (Yanmar HF35F). All my batteries are group 27 lead acid by US Battery.

Thoughts????

Indecision may or may not be my problem.

Re: Battery Switch

Is it the Blue Sea dual purpose switch?

Forget the AM part, but read about the dual circuit switch:

Re: Battery Switch

My 34 came from the factory wired for two banks with a 1/2/both switch. I just made 1 the starting battery and 2 the house bank, so did not have to change any wiring from the switch to the bank.

Re: Battery Switch

I don't think I'm helping at all (surely I'm not)...

My PS37 has a switch panel with separate rotating switches for house and engine, with an "emergency" cross-over switch nearby. I like this because I am prone to make mistakes and the typical 1-2-both switch isn't foolproof. As for batteries, I've got gels that are eight years old and appear to be in ideal condition -- but I also have an apparently very precise charging system and a solar panel, which I assume is the reason they have lasted so long (I try not to use the wind generator when the batteries are nearly full because I don't trust its precision in cutting the charge). I'm toying with the idea of replacing the start battery just to have one newer battery aboard (house bank is four 100AH gels), but it's not yet written onto my to-do list.

Re: Battery Switch

The switch has tree positions, Off, On, and Emergency. In On the banks are isolated from each other unless charging. In emergency they are connected together so you can start the engine or use house electronics.

Re: Battery Switch

Raindog, I assume when you are operating the boat you have the switch on both batteries. Did you have a problem in that position with starting the engine and having the electronics shut down? On Hush, I would start the diesel and my chart plotter would die due to the drop in voltage created when the starter is engaged.

Indecision may or may not be my problem.

I operate the boat on just the house bank. I try to remember to switch it to both when starting the engine, then I put it right back to just the house bank. I only get drop out that resets my chart plotter when the battery bank is near 50%.

I would like to change it so that the starter is wired to the start battery, and the panel wired to the house bank. If I did this, the battery selector would just turn the panel on or off. In the very, very rare occasion I wanted to use the house bank to start, or the start bank for the panel, I would just move the wires on the battery lugs. This seems like the best KISS solution to me.

Re: Battery Switch

Hush34,
We installed the same battery switch, but to make it work I had to make a wood ring in order to mount it in the same location as the old one. I upsized the wiring as well, and it took a little bit of persuasion to get them to fit, but it worked.

I use a Balmar Duo Charger to keep the start batt charged, and it has worked perfectly for the last year and a half. We have had no issues keeping the start batt topped off while cruising. I later added an on-off switch to the Duo Charger (directions in the manual) so that I can turn it off during cloudy days when I want maximum amps going back into the house batteries. I hate cloudy days - makes me cranky when I can't top off the house batts by the end of the day.

Hope that helps. I have more detail on our electrical setup on our website. I keep meaning to do an update post since using the system full time for the last year and half. In short, we are pretty happy with the system.

Re: Battery Switch

I thought about doing a modification like you have but opted to move the switch out of sight underneath a quick access hatch. The wood ring looks really nice though.

Indecision may or may not be my problem.
