Perko switch help
Ok...this topic I'm sure has been beat to death. I've done searches and with such an abundant amount of information I have become more confused than when I started.
I just got a boat and installed a stereo with 2 amps. We parked in the cove and I killed the battery listening to the stereo with the motor off. The boat does have a PERKO switch, however, I don't believe it's wired right. It looks like it's wired in a series (I'll take a pic when I get home) How should I reconnect them? Should I have 1 position for starting the engine, 2 position for the stereo when the motor is off, and put it in the both position when the motor is running to charge both batteries? Also, I would like to accomplish this without spending more money...at least not now...I've spent so much money on sales tax, registration, stereo, insurance, etc, that I'm sick to my stomach! |
oh...and there are 2 batteries in the boat...
|
The batteries could be in series but only if you have two 6 volt batteries.
|
Ok...well I guess they're not in a series...the 2 negatives of the batteries are connected together....

By the way. The negatives of the batteries should be hooked together. |
I've heard about battery isolators...is this the same thing as the voltage sensitive relay you mentioned?

A VSR/smart solenoid/battery combinor isolator basically is just a solenoid that breaks the connection between 2 banks of batteries when the voltage lowers to a certain set point. The one we sell is a sure power 1314. It is super easy to install, fairly inexpensive and basically does everything automatically for you. It also gives charging priority to the starting battery so you don't get left with a boat that won't start. They also don't cause a voltage drop. Being used in conjunction with a perko style battery selector switch and an onboard 2 bank charger you should be able to keep your batteries in good condition for a long time. |
Thanks for the reply! Do you know of a shop that sells the Sure power 1314 locally. I'd like to get all of this sorted out tomorrow.
And what is the purpose the 2 bank charger? |
I would just google and find the wiring diagram. I think that would be the best way to make sure its correct. Schematics ROCK!
Cant find the one I printed out the other night, but i know its on the net (just cant seem to find the exact one I used) |

Ben,
Pollarbill is one of the few who really understands charging systems from top to bottom including where all the dominoes fall as you get into more complex systems. We are in Dallas so we're one day away for freight. I have friends at Custom Sounds who can do the installation in San Antonio. In any case we can do a package that is designed to fit your needs, budget and tolerance for technology. Plus we supply schematics for wiring that pertain to your particular scheme. If this hasn't already been addressed by the time I post (slow typing) a dual bank charger profiles and conditions each battery separately so that neither is over or under charged given that for a variety of reasons each battery will be at a different state when your boat is put up in storage. You will match a charger capacity to the battery(s) capacity. The right multi-stage charger will dramatically extend battery lifespan and give you longer playtime at rest for the following weekend as well as season to season. David Earmark Marine |

Brett,
When using a Perko switch only I like the idea of using two identical deep cycle banks (warm weather and small blocks) and rotating their use each weekend. And yes the same rotation scheme makes sense to me on a little less frequent interval as applied to VSRs. Anything to limit or balance the number of cycles per battery or to limit the depth of the cycles. Is that what you mean? David Earmark Marine |
