Make sure all the grounds are hooked up and clean,remember everything on a plastic car has to have a ground wire.Also,check that there is juice running all the way through the fuse panel,not just at either end of the fuse.I have 2 of these cars,and like yours they have sat around a lot.I found that resistance would develop between the brass fuse clip and the rivet that holds it on.juice would go through the fuse,but not out the wire.If it was wired correctly to begin with you are going to find a small problem,or a series of them.You can download the assembly manuel for that car on this site.It has the wiring codes explained in it.You should have little tags with #”s on each wire and the book will tell you where it goes.The wiring on these is very simple.
