Re: Older Minkota 565

Here's a schematic of what your wiring probably looks like.

I have no idea what wire colors are so you'll have to figure that out. On position 1 all three speed coils should be in the circuit (highest resistance = slowest speed). On 2, the top coil is no longer in the circuit. Less resistance = faster speed. In 3, the top two coils are removed. Still less resistance even faster speed. On 4 none of the coils are in the circuit and the motor runs at full battery voltage. Fast as she goes on that setting. If you use a resistance method to test the switch, it needs to be removed. Test from the input lead to positions 1, 2, 3, and 4. You should have continuity between the input and each of those positions. If you use voltage to test, feed 12 volts to the switch as shown. Measure from 0,1 2, 3, and 4. You should get 12V on each of those pins except 0. You can match wire colors at the switch with those on the motor to determine which wire color matches each speed and hence which speed coil may or may not be defective.

Re: Older Minkota 565

on those trolling motors you may want to check the motor housing to see if the seals are still in good condition, i had one with the simular problem, except mine didn't make it too long after the water got in there, good luck.......if you need replacement parts or repairs done there is a place in Mooreland, Ind. If you need the number I can post it tomorrow.

Re: Older Minkota 565

Hey Silvertip...
The when the switch is out and unplugged each setting 1 - 4 points to different posts....each time I turn the speed dial the Switch makes a different post hot. It doesn;t Bridge 2 or 3 posts together on the 1 setting. each turn of the speed dial changes the Hot post to a different one.....Now with wires connected .....123 posts are hot on 123 on the speed dial. Make sense ? I think I may have a different setup. Unless I've found my problem and have a bad switch.

"On position 1 all three speed coils should be in the circuit (highest resistance = slowest speed)."

only one post is hot on position one with the switch out of the unit. When wires connected pos 123 have posts 123 all hot. I hope I'm reading your post right....But like I said with the switch out each turn of it makes a different post "hot" or has continuity.
thanks for all the help guys !!!!

Re: Older Minkota 565

Hey Since there's no change on the continuity on speed dial settings 1 2 and 3....think I've got a grounding problem between coils or somthing ? In the Lower unit ?

And as far as a speed coil....are they individual windings in the motor itself ?

Re: Older Minkota 565

With the switch IN the circuit, you will back feed through the speed coils so yes, on any given switch setting all the posts will be hot or show continuity. Follow my diagram (its like running water through a pipe). You need to test one way or the other. Get the switch totally out of the circuit. Use an OHM meter. Red led on input. Switch set to 1. Black lead on 1. Continuity = OK. No continuity = not ok. With the switch on "1" measuring from 1 to 2, 1 to 3, and 1 to 4 should show open. If there is continuity there is a problem if not its ok. Repeat this sequence for each post. The key here is you cannont make resistance measurements of the switch with it installed. You can however make voltage measurements but they will be meaningless since we don't know what resistance value the speed coils are unless you measure them. Again, follow my diagram and measure between the wire at each end of the speed coil. Set the switch to OFF. Measure 1 to 2. Then 2 to 3, then 3 to 4 (high). All of this of course is for naught if the motor is not actually wired as I show. You need to prove or disprove that or you are wasting time. I can't see your motor so I think I've done about as much as I can here.
