Who says that you have to jump into the Atlantic ocean? Ever hear of a solar heated swimming pool? Are planning to come down by yourself or with the family?
Now I have to put the F7 back together, the shell is still off, waiting to solder the connections too.

I'm ready, Lee. When can I come down and get it? Ever see what happens to a guy when he jumps in the cold Atlantic this time of year? Not good (or big)!
Congrats on getting your Williams running!

Jaabat,
Are you ready for your swimming lesson?
I got my F7 running with only a bridge rectifier!

I swapped the leads around and it works now! Radio Shack's directions were wrong about wire placement. Before I swapped the wires it would sound the horn in the B unit constantly.
You should be able to use one of the boards that Williams now sell.They have very good instructions and have all the plug-ins needed for the board to be installed.I've replaced a coupl of older Williams boards with these and have had no problems,one in an older DC Trainmaster.

Bob,
I already have a 6 amp bridge rectifier wired as descrbed but the motors won't spin. The little brown wire that goes from the frame of the engine to the motor frame is still conected, from what you are saying I need to disconnect this wire correct?

The brown wire is fine, it's a ground lead for better ground integrity through the trucks.
The "+" & "-" leads of the rectifier should go to the each of the two small solder tabs on top of the can motor(s). Try just that 1st, nothing else, w/ a small accessory transformer powering the rectifier "~" leads to leave everything else out of the circuit. Report back!

Jim boy,
Are you afraid of a little cold water, like the Atlantic Ocean? How do you think that Flipper or his relatives get up to you man?
Anyway I contacted Larry Harrington @williamstrains.com by email, the reply was he would get back with me later. It was an automated reply!
I find the people at Williams very helpful even when they don't have an answer for you.
Going outside to work on my sprinkler system, have to do something on my day off!

Looking to wire it for running one direction all the time.
Already tried a bridge rectifier and it didn't work.
The bridge rectifier should work, ...that's all the HO power pack is. All my Williams engines run just dandy on DC from a bridge rectifier.
The "~" terminals/leads go to the track(either order - it doesn't matter) and the bridge rectifier "+" & "-" terminals/leads to the motors, and you are ready to roll. Switch the "+" & "-" to change the direction.
Jimbo,
Is that anything like taking a long walk off a short pier?
Philly, I guess you're screw-diddly-ooed!
Jim,
The diagram don't match my circuit board!
Williams has a diagram on their web site that shows you how to wire and engine to run or be "locked" in any direction.
