2 battery questions
Hello all,
I have a Tige 22v riders edition. Great wake boarding boat, we love it. I have 2 questions - I hope someone can help me out w/. 1. It has a main power off switch in the engine compartment (A twist knob). Ive noticed that if I dont turn this off at the end of the day and the boat sits until the next weekend the battery will be dead. I cannot seem to figure out where the draw is coming from. Ive tuned everything off in the boat. How can I track down the "leak". The real pain in the ass thing is each time Im done for the weekend and I turn the main power knob off - I lose my radio stations each time I do this which leads me to my next question.... 2. The boat has 2 battery compartments. Id like to add a second battery so the radio works off a seperate battery vs the main one the rest of the boat uses (ie starter, lights, etc...). (I want it be transparent as well - ie - I dont want to have to switch some switch) Is there an idiots guide out there somewhere that shows how to do this? I can pretty much build anything and am mr fix it so installing something wont be an issue - but for some reason me and mr electricity dont get along all that well -so a well drawn out electrical diagram would be really really really good!! Any help would be appreciated. Thanks |
If you add a second battery, use one of them strictly for starting the
engine. Don't follow your plan to use one for the radio, and then put the starter, the lights, and everything else on the other. The most important electrical funciton on your boat is starting the engine. If you can get the engine started you can recharge a dead battery hooked to the stereo, etc. Now, however, if you're a young single guy and you use the boat for dating- ignore my advice. Rig that son of a gun so the engine battery is stone dead about the time you reach some secluded little cove. "Golly, Esmeralda- it looks like the engine won't start and we'll have to drift around here for a while until somebody comes by to tow us in..... In the meanwhile, we can play the stereo and there's some cold beer in the refrigerator" :-) |

Ive tuned everything off in the boat. How can I track down the "leak". Hmmm - well, if you aren't One with Mr. Electricity, then it will be harder to diagnose why the batter is dead when it's essentially disconnected. The only thing I can advise is to check that the two wires from the battery to the switch and make sure the switch is wired properly. You are looking for a break in the negative or positive line - make sure it is a complete break then the switch is off. You can use a test light (a screwdriver looking deal with a long pointed end and a light bulb in the handle and a long lead to connect to ground - available at any auto store) and check for live wires after the switch when the switch is off. It's also possible that something is wired around the cutoff switch and if I had to bet, it would be the radio. I've seen this happen and while the memories don't draw a lot - if the radio doesn't have an internal station memory (flash memory) - then over time, 24/7 it will draw down a battery significantly. The only solution to that is to purchase a radio with flash memory and hook it up to the power source after the cut off switch. The real pain in the ass thing is each time Im done for the weekend and I turn the main power knob off - I lose my radio stations each time I do this which leads me to my next question.... 2.

It would help to see a schematic of your boat, but I think that adding a separate battery really isn't going to help you any. As Chuck said, it's better to have a battery wired just to start the boat and a second battery to run everything else. Having said that though, I'd try this first - next time you use the boat, disconnect the radio's power line and see if they battery draws down. If it doesn't, then there is something else wrong, but I'd bet it's the radio. After that, we can get into details. Later, Tom |
Just run the radio "memory" wire directly to the battery (+) and remember to
fuse it! "Rob V" wrote in message . com... Hello all, I have a Tige 22v riders edition. Great wake boarding boat, we love it. I have 2 questions - I hope someone can help me out w/. 1.

if you wish to run two batteries thoeugh. you need a battery
isolator/rectifier. NAPA and most auto parts stores carry them. as well as all your camper/RV joints. super easy to install, this will allow you to charge both batteries at the same time, yet will allow you to pull current off one while having not drain effect on the other. |

Ive tuned everything off in the boat. How can I track down the "leak". I'll have a go, at least the corrections of my attempt might help you:-) Most things in the boat should be fused, either with one of those placky inline fuse holders or often the fuse is part of or next to the panel switch. (i) Take the positive off the battery & put an ammeter in series. (a cheap $10 multimeter is fine, most will read up to 10amps & the leak won't be that big:-)). (ii) Make sure everything seems to be "off" (iii) Turn the main power switch on, the multimeter should not show much flow, maybe a very low milliamp reading only. (iv) Lots of things on a boat draw tiny amounts when "off" VHF radios, the ordinary receiver you mention, some depth sounders etc etc almost anything that has a memory, so a very small flow is not a problem of itself. (v) If you get a largish reading say 2 or 300 milliamps it confirms what you already know, that there is a "leak" (vi) Start a process of elimination easiest first, by removing fuses one at a time till you see the flow change, whichever circuit kills the leak ( or most of it) then you can look further. If you don't have any impact on the leak by removing fuses etc then get more creative & start by taking the main lead off the alternator (the diodes might be leaky & don't accidentally earth or you'll need another $10 multimeter:-)), alternator field wire if there is one, then other likely candidates which operate in a damp vibrating environ & leads off other parts of the system always one at a time. (vi) Once you know the circuit/general area the leak is in then try to fix, sometimes it can be salt/corrosion buildup (when damp it's conductive) or a wire somewhere has lost it's insulation (crushed behind some trim?, someone put a self tapper through it? it's just got worn etc. The real pain in the ass thing is each time Im done for the weekend and I turn the main power knob off - I lose my radio stations each time I do this which leads me to my next question.... The radio memory only draws a tiny amount, some people hook up an ordinary 9 volt alkaline battery to keep all the memory things alive when the system is "off" The 9 volts is enough & one battery should last you the season. 2.

I can pretty much build anything and am mr fix it so installing something wont be an issue - but for some reason me and mr electricity dont get along all that well -so a well drawn out electrical diagram would be really really really good!! It's not difficult & most multi battery switches you'll get from the chandler shops come with pretty clear instructions about the wiring. You might reconsider your wish not to "switch some switch" because you can control the system pretty well with a manual switch, just so long as you don't switch to the off position when the motor (ie alternator) is at high revs. Any help would be appreciated. Thanks K The Krause lie of the day is well um sorry............it's the truth!!! This stalking idiot thinks that because Madcow didn't protect herself to his standards it makes it totally OK for him to "secretly" spy on her, then post denigrating posts about her boat her appearance etc etc etc, clearly because the lying pervert Krause has no boat much less CG training as Madcow did, he was jealou & set about stalking her. He finishes off with a nice little stalkers boast to John, just letting John know he's checked out his address etc. Oh by the way this post?? he made it yesterday!!! a sick & very dangerous liar is our Krause. As for Ms. Klummmmmpppp, she outed herself. Madcow made a big deal of her volunteer work as a "boat safety inspector," and her work for her local power squadron, and even invited folks to look at her USPS home page and see a few "knot animations" she said she did. Lo and behold, there on her local USPS home page for the world to see were photos of Dolores and her boat, and a chart listing the names, addresses, and telephone numbers of the local chapter's USPS "safety inspectors." Including the delightful Dumblores. Oh, she also told us the name of the marina where she kept her Bayliner, and the fact that it was next door to her apartment high-rise condo. BTW, John, you were practically a neighbor of mine when I shared an office in Alexandria. At least I think you were. How close are you to "Rose Hill"? |

There are 2 power wires to modern radios. One to keep the station presets and to to keep the anti=theft circuit alive. Then there is a power to the radio and amplifier. And most wakeboarding boats I see have large amps, for the big speakers on the tower. So just run the preset wire to the battery and and turn off the power switch to all else. For a 2nd battery, use either a battery combiner or battery isolator. |
