help vexilar problem

13 posts in this topic

I bought a used fl-8 and it is having a few problems. when I bought it I turned it on and it seemed to be fine. I turned it on it spun a couple of colors showed up a top screwing with the gain made more colors show up

right now it when you turn it on the fish alarm goes off continuously and the lights come on for a little bit and then shut off while the disc keeps spinning

Here is what I have done

1) switched out the transducer. it came with a puck style transducer i bought a 19 degree floating one I was planning on using the puck style for open water.

2)charged the battery initially the lights went off then after I charged the bat for a few hours it seemed to work normally

3) cleaned the inside and the contacts for the brushes per the instructions on vexilar's HSOforum. The colors were dim and the unit was filthy when I opened it up I found a lot of dust and the rings were dark but it all cleaned up well i couldn't see and burn marks on the board or other signs of problems

Finally i have a few questions about normal functioning of a vex

1) when you turn it on out of water should it function the same as out of water. What i mean is should it be able to pick up my hardwood floor as the bottom if I hold it 5 feet off the ground should I be able to see my fingers pass under the transducer?

2) What does a failing battery cause a vex to do? I have no idea of the condition of the battery it came with

3) is there a problem using a 12v battery. This is a vexilar battery but they only sell 9 and 7 on the HSOforum

4)is there anything else anyone can think of

I dont understand #3? they are all 12v batterys, just the amps/hr is different. get the 9 amp/hr if you are going to replace it. Mine does not pick up the floor, etc. when it is out of water.

If you have a buddy that has a good battery, I would try a battery that you now is good. If that doesb,t work, call Vexilar and they will be more than happy to help you trouble shoot your problems.

If you look on the web site,look for the tip on ice ducers.It will teach you how to set up the transducer to shoot properly.

I agree with Harvey. Try a different battery. Any 12 volt battery will work to do a test. I would say that 10.5 volts are a little low for the unit to work properly.

If the battery sat poorly charged for an extended period it may take up to 6 days to recharge fully again..or it could be shot.

Try a known good battery and see, and if it is shot replace it with a 9 amp 12 V and you should be good to go.

My FL8 pickes up my hardwood floors, but since water is denser then air there is a multiple of 3. 3 feet will equal a reading of 9 feet. and if I put my hand under the puck it does show up on the vex. I've had my battery run low and it will start to act up, but mostly it's just not as bright, then it'll just not show up anymore. BTW a 12v battery at full charge should read 12.3volts or so.

The speed of sound in air is about 342 meters per second, while in freshwater it's about 1500 meters per second. In essence it should be closer to a multiple of four. I always wonder why I can't get a foot reading when I put my hand under the transducer only about a foot away.

All sounds normal except the battery. A fully charged 7-9 amp sealed battery should hold a charge of between 12.3 - 13.1 volts.

my battery may have taken a dump also...i took it out with low juice and ran it almost dead...i couldn't see the battery light to tell how much juice i had in the bright sun.

it ran fine for awhile then the lights around the screen just kept spinning like a wheel...so i shut her down...now its been plugged in for 3 days and still isn't fully charged....i drained it before on fishing trips but i never remembering it taking this long to fully charge.

sounds like yours is a battery issue also imo

    • It would probably be more accurate for you to say you simply choose not to believe it will be a problem.   What happens to your theory if interest rates rise to 5%?  
    • All depends on the district and how many years you have been a teacher.  Although MN is looking for teacher all over.. Our current district decided on keeping befits really high and seeing an increase in pay. Where my mother in-law (down in the cities) they have great benefits but there wages haven't not increased as significantly..    Although my wife is looking to open a daycare up so we knows if she will be teaching after all? 
    • You'll be fine with the door in the V.  I heard at one point that the Lake of the Woods edition was Ice Castle's most popular layout.  I know I see tons of them, but you will have to take some precautions.  I use a Towtector on my truck, which keeps the majority of the slush down.  A piece of tape or a tennis ball over the door knob is also done frequently.  Other than that, you'll have icing and freezing of your door, regardless of where you put it.  Just the nature of the doors we use.       
    • That does happen a lot and it sucks having to play those games.  I took my contract job knowing I was going to keep looking for full time work so it was really just a stop gap to get pay checks coming in and also to gain some experience in a new area and with a different company.  I think i was there less than 2 months total including the 2 week notice I gave after accepting my full time job.  Often times its easier getting a job when you're already working somewhere as you are viewed as more employable.  If you're not working then employers start to wonder why. That where a short term contract job can pay off.
    • I'm lucky enough to have the choice when I start my day, usually head in before traffic gets bad(6:30), but today I woke up and was like..........I'll wait until after rush hour(let that carp melt). We have a guy that starts at 4:30 am, and others that roll in at 10:00 am.   35W-494-Hwy100 on the way in, but I avoid 494 like the plague in the afternoon and cut through Bloomington. Adds a few minutes time that way, but it's always the same amount of time,  I hate hate hate the accordion traffic of 494. Jump on 35W right before the MN river and I have my own lane, no merging needed.   Curious to see how shutting down Hwy 169 is gonna affect things. Might roll in even earlier if need be.   Started working from home on Friday's two weeks ago, it's nice but I don't know if I would ever enjoy working from home full time. Stir crazy and lack of interaction with other folks.   Living on the south side of the metro stinks for taking trips up north. But we live with fewer meth mullets around.   We picked where we wanted to live first and then adjusted how far we were willing to travel for a job.        
    • Ya a saw that, sounds like they have played an easy schedule but you still have to pretty good to have that kind of record.
    • One could also say Koivu has been reborn, that line has been on a tear lately. I think all of them are at or near a point per game for the last 22 games. Not to mention they are doing that while usually getting the job of shutting down the other teams top line. Crazyness!
    • most people are pretty good in the shanty towns that I frequent.  the thing that pisses me off is the guys that come out with there 50 grand fish house and there 5 dollar generator.  instead of leaving it in the back of the truck where it wont bother anyone they drag it 50ft front there house set it next to me and let it buck very annoying.
    • Maybe you can help me understand something.  He mentions his wife is a teacher.  From what I have been told and through reading doc's through the MN Dept of Education, teachers generally get paid the same.  I understand there is a little "bump" for working in the cities, but doesn't the State Teachers Union dictate what teachers make to some extent?  My daughter wants to get into teaching and I was just curious.  I highly doubt a English teacher in Shakopee makes $15,000 more than a teacher in Detroit Lakes when comparing degrees and experience.  Hopefully MJ can offer some insight as well. Thanks!
    • We had kids.   Well it's not really that bad though...
