Preparing The Chassis For The
Proto-Sound 3.0 Upgrade
Before you can install the Proto-Sound 3.0 components into your locomotive,
any existing sound boards or reversing units must be removed. The Proto-Sound
3.0 Kit contains all the necessary electronics your locomotive requires to
operate. Some existing mounting brackets may be utilized during the installation
of the Proto-Sound 3.0 components. Follow the instructions below taking care to
save the parts when noted.
Remove The Following Items From The Locomotive Chassis
- Body shell (save the mounting screws).
- Proto-Sound 1, DCRU Reverse Unit, Mechanical Whistle, Electronic Whistle,
any other electronics and harnesses.
- Speaker (save mounting hardware).
- Existing couplers (save the "T" bars, springs, and c-clips).
- Any lights including the headlight and marker LEDs (if present).
These will likely be mounted inside the body shell.
- Volume pot or smoke unit ON/OFF switch may be reused or replaced with the
new pots included and connected into the new wire harness.
- Battery Charge Jack (if present) and retain screws.
- Do NOT remove red wires connected to pickup roller assembles. (Inspect the
wires and replace with wires supplied in the kit as needed.)
Note: Leaving a short piece of color coded wire on each motor terminal will
help ensure that the new motor wires are hooked up to the correct motor
Terminals and allow each motor to run in the same direction.
