I have a mode shifter job this weekend. I have one customer, he has about 20 GE Commercial washers, I have already done 3 for him. Im gonna take the old mode shifter and try this. I think the external fuse would be a good idea, maybe an auto fuse and holder. You can get them at radioshack for about 5 bucks for both. I'll sell him a " rebuilt " mode shifter for less, we both win. I hope this works.
