Williams lock out reverse

Not sure if this will help you, but on my older Williams F-7's I installed a 6 amp 50 volt bridge rectifier after removing the circuit board for direction. To wire a bridge rectifier is rather simple; run the two A.C. powered(from track) to the connections that have a ~ , then use the positive + to one motor wire and the negative - to the other motor wire. If it don't run the correct direction simply reverse the + & - wires.

Of course by doing this you lose all direction control, including nuetral, except for forward.

Instructions for adding a direction lock switch to a Williams or Williams by Bachmann loco can be found here: http://www.williamstrains.com/...Instruct-Lockout.htm

Lee, thank you, not what I had in mind, 

Len, I guess I should have checked their site first, that is what is needed.

Does this mod lock the E-unit in a particular position, or does this mod cause the loco to power up in neutral before forward? It's not clear from the minimal written instructions.

Roy,

You pose a good question, even I didn't think about that.

With the bridge rectifier you know what direction you going in and that's it!

This Mod allows the loco to start up in neutral first;

So the modification does not defeat the e unit?  That is what I want to have happen without adding a bridge rectifer. 

Seems like a little thing that should be standard on any conventional loco, at least to me. 

necrails;

There are 2 different Mods to the Williams/WBB reverse unit. One Mod adds a lockout switch to lock the unit out in Forward Only( Not 100% sure if just forward or any position) The second Mod allows you to change the startup from forward to neutral first. Both Mods can be found on the Bachmann Web site. You might try a post on the WBB board to confirm the lockout switch. Hope this helps.

Williams locomotives start in Forward position by default.
