Just clean things up, and maybe tighten up the fuse holders so there is good contact, reconnect power and see what happens. -tim
One of the things I've learned from playing around with old tractors is that you need to periodically check all your electrical connections. Loosen each connection (one at a time) and clean off any corrosion.
It's a mantra with old tractor folks: "Keep em clean, bright and tight".
I have found that what works very well is a called a fitting brush - used for polishing the insides of copper fittings used in water lines before you solder them together.
and keep us posted on your progress.
