I recently replaced a very noisy e-unit on my Lionel 2338 (vintage 1957) GP7 with a Williams 00247 electronic unit. (Bridged the field winding with 4 1N5400 diodes to provide proper power flow through the field winding). Performance is great, it's almost too quiet now, but I like it. Would like to install a lockout switch to enable continuous direction running for MU lash ups. Anyone know how this can be done? Nothing in instructions from Williams on this.
