How to Identify and Resolve Common Issues ?

We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :

Check your transducer and transducer cable for nicks, cuts or physical damage. Try to repair any nicks in the cable with electrical tape. If any have had the internal wires cut or separated, the entire accessory should be replaced. Damaged transducers should be replaced.
Check the Connectors & Pins

Check the pins of all connectors, to make sure they have not been bent, broken off or pushed back into the connector plug. If any connector pins have been bent, you may try to straighten them with needle nose pliers. If any pins are broken, replace the entire accessory.

Wire the fish finder direct to the battery (either the cranking battery or an auxiliary battery). Don`t take shortcuts and run the fish finder power wire into a block or switch panel. Wire your fish finder the right way and extend the Humminbird power wire directly to the battery using the correct type and gauge wire.
Press POWER once to turn the unit on. There will be an audible chirp when any button is pressed to confirm the button press. If the unit does not power-up, ensure the unit is fully seated on the mount and that power is available or that all connectors are tightly screwed in.
Excluding special super compact fish finders, most fish finders use DC 12-24 volt power supply. As long as the voltage is between 12 and 24 volt, the fish finder unit will function properly.
In general, you should be able to get years of life from your new fish finder battery. However, all batteries have a lifespan. We expect our ELB lithium ion battery to last approximately 2000-7000 cycles until they should be replaced.
It is not recommended to run a FishFinder and transducer on a boat that is not in the water as you will not get any readings from the transducer.
All screen sizes are fully networkable, including Ethernet, Bluetooth, NMEA 2000 and Wi-Fi, and offer models with multiple sonar technology options.
Transducer Orientation – improper orientation of the transducer can cause the depth sounder to not `see` fish. For a unit to be able to show fish, it must have a transducer that is facing straight downward. Most transducers must also be oriented in a particular direction with respect to boat movement.
You will not be able to test out the transducer`s ability to read depth when the boat is not in water. Air dissipates the sound waves produced by the transducer and will cause the transducer to not be able to produce a reading.
Sensitivity and contrast go hand in hand. Humminbird fish finders, for example, come pre-configured at “10 and 10,” which simply meads a level 10 setting on a range of 0-20. The 10 halfway setting is optimal in most situations.
We service and repair complete units. We do not sell internal components to our fish finders or transducers. If the unit has physical damage like a cracked or broken display, please call us for a quote.
The Sensitivity or Gain of the unit must be set high enough that it will detect the return signal of a fish. Try turning the Sensitivity/Gain to a higher setting. Sensitivity – all Sensitivity menus to a higher setting. Surface Clutter – adjust so that less surface clutter is blocked.
If there is a bottom reading but there are no fish or suspended targets, it is likely caused either by trolling motor noise or placement of the transducer. From the Fishfinder or Chartplotter sonar screen press the menu button, select Gain and turn up the gain settings to 90 – 100% while running the boat at speed.
Check the transducer connection in the control box as well. If the Built-in MDI transducer is not submerged in water, the Humminbird screen will appear black (it could also display as white, green, red or blue depending on the background color you have selected).

Slide out quit working and fuse on battery blows everytime I chan
ANSWER : Look under the coach near the slide and look for a pinched or bare wire. Sounds like you have a dead short to ground and could be difficult to find. Check the wiring to the slide motor, could be between the slide switch and the motor. Take a Volt meter and set it to Ohms. With the fuse out check to see if you get an Ohms reading between fuse wire and frame of coach. If you get a reading you have a short. Also check the power wire on the slide motor to motor case. If you get a reading the motor is shoted and needs to be replaced.Thanks for using FixyaJerry

I just put a new battery on my 2000 Yamaha G16A gas golf cart and now it won’t do anything. We have headlights that are straight wired to the battery and they work fine. I found a blown 10 amp car type fuse that was blown and straight wired around it and that didn’t fix the problem. I know it is a wiring problem because the back-up buzzer won’t even work. Is there another fuse that I should be looking for?
ANSWER : Yes, check the main fuse trace up the main cable so that you can see it. Then don’t forget to check the wire in main sw. or key.

Have a 2004 kawasaki 3010 desiel mule that has worked fine for years with regular maint. then yesterday we started it as usual with the glow plug lights indicator and it ran for a few minutes until we went to take of and it just died. period. we tried to check thing out and finally found a bad fuse in the glow plug fuse holder, changed it with the same size and it ran the rest of the time we needed it and then again today we started and ran it same as yesterday and it worked fine for about 30 to 45 minutes and will out in the field it just quite. i immediately started searching for signs of heat or melting of wire or other signs and found none. the fuse that goes into this circuit is a 5 amp and all i had was a 20 so i said lets see what happens. it immediately blow the fuse without any out ward sign of problems.??????
ANSWER : Replace the glow plugs one or more are shorted

I have a wildwood le 25bhbs and the only towing lights working are my signal lights. can’t get running lights or brake lights to work. I saw where it looked like the towing harness may have been pinched. So I repaired that, but, they still do not work. Any ideas? Is there a fuse somewhere I need to check? Do I need to hook the trailer up to my trailer hitch before they will work? Is there a wiring diagram or repair manual somewhere I can get? Any help would be greatly appreciated. Thank you.
ANSWER : There should be an inline fuse, check that first.

I have purchased three 750-watt power inverters in the last three weeks. They have all failed to work on the second or third use. The first two were the same brand. I replaced an old one that ran for several years. I am using it to run a 4.7 amp 120-volt vacuum cleaner motor that pumps up my air dock. I have it connected directly with marine cable to one of the boat batteries. The battery outputs about 12.8 volts DC. The fuses don?t blow, just No Output. I am using a three-wire 120-volt extension cord and am, wired neutral, hot and ground to the AC motor vial an on/off switch. The motor works fine when I run house power with an extension cord from the dock next to me. Could I be, just unlucky with new inverters and need to buy a forth one?
ANSWER : The problem may be that the inverter is undersized for the load. Is the 4.7 Amp rating the motor peak draw or the nominal one. What I mean is that it takes many times more power to start start the motor than when the motor is running. Typically it is 3 to 7 times more amps to start the motor than when it is running. It could be that starting the vacumm cleaner is stressing the inverter and it is causing it to fail prematurely. If you can find out the locked rotor current draw of the motor, the that would be the mininum size of the inverter.

Also, the type of inverter will make a difference on how the motor operates. A modified sine wave will make the motor run hotter than a pure sine wave inverter. Hope this helps.

I would like to hook up a 12 volt battery to the trailer. In the cupboard below the propane stove is a plug with white, black and orange wire to it.
In the AC power converter cupboard I have a plug with a black and orange wire. How do I hook up the battery so that it charges and runs the fridge while I’m driving, and lets me use the lights with the fridge on propane while I’m camping?
ANSWER : You haven’t told us what trailer you have, what DC-AC converter you have, it the wire is original or aftermarket and what gage it is.

Because of that you must first identify the wires. You will need a multimeter for that. Start by finding if your trailer has a negative wire or is using the chassis as the ground. For that disconnect the battery from the truck (make sure you have the radio code handy) then measure the resistance between the 3 wires and the body of the truck – you will find the ground wire when the resistance will be close to 0. Reconnect the battery and measure the voltage between the ground wire and the other 2 – the one with 12v on it is the power one and the other goes to the power input of the converter. Check that by removing the converter and looking where they are plugged – if you have any doubts that they are not the wires from the cupboard just check their continuity.All of this is a 5 minute job. Once you know the wires just connect the ground on to the minus and the power and the converter ones to the plus.

I just bought new batteries for my Club Cart Golf cart. It worked fine before I changed batteries. I drew a diagram of the wires to ensure I reconnected them correctly. Now the cart will go backwards, but not forward.
ANSWER : You have the motor hooked up in reverse, you need to switch the two wires leading to the motor in order to fix it.
