I have a Motor Guide trolling motor that quit working on speed 1 and 3. Took it to Tom at Motor TECH in Suffolk,Va. for repairs. Tom told me what the problem was ,and he was right. The solder joints on the 1 post and the 3 post was different and poorly soldered. It seems this is a commom problem.Maybe Motor Guide needs to hold soldering classes. Saved me a lot of bucks.Thought I would pass it along to everyone......Waiting for cool weather.... crappie1133
