And a couple more.
All I did to fix it up was extend the rather short motors wires back out to stock length ( I finally mastered butt jointing wires, looks so much neater than my usual efforts), and re-instate the battery leads for dual pack operation; no plugs on there, but hopefully the future new owener will prefer to choose their own regardless, and solder them on.
Fun times ahead though, as in about 3 weeks we break up for summer leave, so I have a month or so of free time to play with my truck, good job I have so many batts now that can be charged in only an hour or so each...
