Hobie Bait Tank Problem

Have you checked your battery with a voltmeter?

I tried to check how much "juice" is left in it but not sure how to do it. Searched it, and I think I need to use a resistor or something. I believe just using the voltmeter alone will only give you the reading of how much "juice" it can hold.
correct me if I'm wrong.

It should be very quiet with the 6v. Also the pump at 6v should be trickling water in so don't expect a fire hose. A voltmeter will tell you how much voltage is coming out of the battery. Non lithium batteries will vary in output voltage depending on the battery and what kind of condition it's in. Odds are if the battery is good, at fully charged you will get at least 6 volts if not 7. As the battery drains somewhere below I think usually around 30% you will see voltage begin to drop and the pump will slow accordingly. Be sure the voltmeter is set to VDC 20V when you use it.

Make sure your intake tube is primed!!!

your pump is fine , you have already tested it at maximum voltage . a new hobie battery will test out at 6.7 or 6.6 volts . a strong battery is gonna be 6.5 - 6.4 vlts. , and so on . a questionable battery or bad battery is obviously under 6 vlts . putting the battery under a load would be ideal . . maybe autozone will check it for you . .assemble the tank and attach it to kayak . turn kayak over , and check how far the tube is hanging down under the kayak . the tube needs to be protruding below the water line of kayak . as mentioned above ,the induction side of the tube needs to be facing the front of kayak . have you eliminated this from the equation ? the tube should have a zip tie to attach the tube , and a rubber o-ring to make a complete seal . if the guy sold you a working tank , i would think the induction tube is long enough , but maybe he cut the length to fit his kayak . and finally already mentioned also , you can test the tank by placing in a 5 gallon bucket full of water , you will need to prime tank manually by inhaling on outlet side of pump . this can be done with a hose extension attached to the outlet side of the pump . there are posts on this modification . a constant supply of water will need to be added to bucket , like a garden hose hooked up to outlet . if none of this makes sense , feel free to pm for pics .
