Working electrical issue without wiring drawing
because we cannot find one! Truck runs in reverse,
but not forward. To go forward, the "dual fwd/rev contactor" pulls in both sides, ie not the forward side by itself. We installed all new solenoids. The two that we believe are forward and reverse had burned diodes across the 24v control posts, but because of being destroyed, we do not know which direction to orient new diodes.
We feel this is the solution to our problem, but do not want to
install the diodes incorrectly. Any help appreciated.

Fact of the week
In Germany, the 9th of November is sometimes called Schicksalstag, the "Day of Fate" because it has been the day for several major historical events, including the horrors of Kristallnacht in 1938 and the fall of the Berlin Wall in 1989.
