Saturday morning I lost two speeds on my Motorguide Pro Series 70# trolling motor. Speeds 1 and 2 quite working, but 3-5 still work. Although, there is no difference between 3 and 4.

Could this be the switch under the foot pad. A rheostat switch or something?

Thanks for any help. I've found the switch online, but it doesn't say if it's universal to all the trolling motors or if there are different switches for different models.
