Title: 22 amps in reverse with a minn kota
Post by: camtheman on February 09, 2012, 08:39:28 PM: anybody have any thoughts on why I would have a 22 amp draw in reverse? the prop is not turning and the amp clamp reads 22. something
forward fine and 3 ish amps

thanks
cam

Maybe there is some electrical type fishing/mechanical wizz on this site who can shed some other observation. What type of poundage on that Minn and battery year and type.

Possibly triac or thyrystor output stage? Nothing you can resolve yourself I'm afraid. But if you are in Okanagan I could help 8). I work in electronic service shop.

Post by: fisher man on February 10, 2012, 07:22:27 PM: The motor is siezing, not the prop. The reverse mechanism, which i'm not familiar with is not engaging. the motor needs to have a load(resistance), if not the motor is a dead short or locked motor current. The motor needs the drive shaft (prop) to work. My opinion is luck into why the reverse is not kicking in.
Cheers hope it helps.

Can it cause damage from being locked out?

If I recall correctly, is the LMC basically the resistance of the coil as opposed to the normal operation (with less current) with a choking field (for lack of proper term) due to the induction?

Post by: fisher man on February 11, 2012, 09:01:08 AM: Yes it will burn out the motor. stop running it until you can fix it. Doja it's been 15 years since i was in 3rd year school so its all kinda blurry.However you are kinda right , but it's counter induction that the motor needs as the resistance.Which is created when the motor drives the shaft. I could try to explian it but i would propably just make it worse, so i checked it out on google and its all there. Just punch in "how does a dc motor work". you'll see that the armature chases the North-south polarized magnets, that causes the armature to turn in a certian direction. If you want the opposite direction then you have to change the polarity of the magnets. In this case i believe that what ever changes the magnets is the problem.
