bought a used manual on ebay but got lucky i guess.
get me your email and i can send you relevant pages.
sounds like your f/r switch is not working properly if it works fine when you push the F and R relay in manually.
1 relay is for forward and the other is for reverse.
also check the tracers on printed circuit of relay card.mine had some compound/poting on it that ate through the copper.hard wired the connections and good to go.
