Question about Minn Kota Maxxum 80 Freshwater Bow Mount With Us2

1 Answer

I was using it when all the sudden it just quit working. I have had it on charge for two days thinking it could have been the battery. I know the battery is charged, I have checked it. I have power at the plug in located on the front of the boat so I know it is getting power up to that point. I also took the botton plate off and checked for power under there and have it there as well. I think it could be the power switch but I am not sure. Please help. Thanks Scott

Hey SCOTT ..
Get a multimeter (to check voltage) Verify you have 24 volts coming to the front plug. Now - VERIFY that you are getting 24 volts to the switch. ..All OK..- Now to check the power switch. Disconnect the two wires on the power switch and CAREFULLY connect them by hand.. now SAFELY see if the prop will turn. If the switch is bad, bypassing it will make the prop spin!
..If the prop still does not work,, keep following the voltage.. For more help, trust these guys!:

Hello Jim. You have lost your power some where. Start with the wire & terminal connections to the battery. Open the bottom of the foot pedal and check the wiring connections there. Note be very careful here for you have the battery still connected. You may have a fuse in line some where blown. You can check for voltage with a VOM(volt meter) on the wire terminals. Good Luck.

SOURCE: we have boat that came with trolling motor, boat

My guess is the motor has leaked water into the lower motor assy (behind the prop). and needs to be cleaned up and the brushes replaced.
here's a schematic:
Edge 40
You can try this to check for water leakage:-
1) disconnect from power supply
2) remove the prop
3) you will see 2 bolt heads behind where the prop was. Remove ONLY ONE of them for now.
4) if you see the bolt (it's about 8" long) is covered in what looks to be blask, oily/watery or rusty condition then you know that you'll need to overhaul it.
5) if it IS the motor assy, remove the other bolt and disassemble everything noting their location.
6) I would recommend replacing the brushes Part# 188-052 and the seal kit 2883460.

SOURCE: trolling motor will not operate.

it seems like you have a short have you taken it apart sometimes a wire can fray and it will cause things to act funny see if there is a loose wire you can also use a digital meter to see if you have continuity on both ends of one wire disconnect wire so nothing is hooked to it an select continuity or the beep noise indicator and hold on both ens of wire this will let you know if there is a break in the wire it should beep if it is good

SOURCE: batteries are full load, checked


Be careful when using your motor when fishing in thick vegetation. If this wraps around the prop it causes overloads and higher currents. The high currents cause general overheating which affects all parts of the motor. Check for low battery voltages and for loose cable connections that cause resistance and loss of motor power.
1. Check for loose connections in the speed switch and potentiometer.
2. Check for loose connections within the top housing.
3. Check the rotary switch for burning or other visible damage.
4. Check contact continuity or resistance with a multi-meter or short out each speed terminal to verify the switch contacts. If switch is in good condition one or more speed coils may have failed.
Lastly you need the right batteries, the right charging system, the right wiring and the right charging to keep your trolling motor online.

PBS 18 li-2 bosch cordless drill lights on but no power.

You are sure the battery is charged OK? Bosch Li-Ion drills have a feature whereby they stop working when the battery is low but not discharged right out. This is to extend the battery life as it does not like being flattened altogether.

This happens quite suddenly, from one press of the trigger to the next. It can make you think the drill is faulty.

If the battery charge is OK, then maybe
- trigger faulty
- motor burnout
- broken contact on battery or in drill battery shoe

Dead phone

I know this sometimes happens with these smart phones; one day they just up and quit.
You could try a fresh battery, and check your charging source.
Mine did something similar a couple days ago - I thought it was charging all night long, and in the morning when I went to turn it on... nothing. It ended up being my charging cable, it wasn't putting any juice to the phone.

Do you charge it from an outlet of via usb cord? If from an outlet, the charger just might not work anymore, but the usb cord that you use to put media on the mp3 player will charge it also.

Battery charger won't charge

I'm sorry to say I don't know much about Olympus digital cameras, I've never had one on the bench.
I would take your camera and charger to a shop that sells Olympus batteries try a different battery first, this way you can try it out before you buy and make sure the camera and charger are working ok...

The battery is a Li-Ion, when these get flattened too far they shut down and will refuse to charge, they can sometimes be recovered by using a power supply to lift them but you must be very careful (use a 300ma wall wart at just over the rated voltage of the battery for 10 mins then put it back in the charger) as they can catch fire if over charged, shorted or connected backwards also if its been so flat it refuses to charge its certainly past its best and should be replaced as its likely it will let you down again.

On the other hand it could be the charger, so best to try and check out both before buying anything.
If it happened very suddenly and the battery was still able to run the camera for quite a while I would think a charger problem is more likely, if the battery has been taking less time to charge recently and lasting shorter times its more likely the battery..
Having said that the protection circuits can shut down a seemingly good battery for other reasons.

If you find its the charger third party (non Olimpus) chargers are available quite cheaply on ebay as are batteries

Best of luck

Apc ups flashes red light to replace battery, but battery is new

i think by replacing the battery has not been the solution to the problem

u need to check the battery charging voltage when turned ON with main electricity, if no voltage present from charger, there is no question of battery getting charged and also once the battery is down with charge it may not re charge hence the indicator and alarm.
recomended to nearest service centre
