Last week had 2 amp fuse blow. Put in a new 2a fuse. Now, the ski won't start unless I take out the 2a fuse. It will start in "reverse" without the 2a fuse in. Checked other fuses including 30A. I tried putting in another good 2a fuse but still the same issue. The motor sounds fine, issues up until this...Any ideas? Thanks in advance for your assistance.
