<p>[quote user="CSX Robert"]</p> <div class="quote-header"> </div> <blockquote class="quote"> <div class="quote-user">rettop</div> <div class="quote-content">I'm wondering if capacitors can be added to the turntable to eliminate this problem?</div> </blockquote> <div class="quote-footer"> </div> <p> </p> <p>No, because the DCC power is AC.</p> <p> </p> <div style="clear:both;"> </div> <p>[/quote]</p> <p>Yeah, oops.</p> <p>Any way.</p> <p>As far as mods go...</p> <p>There are 3 rings on the bottom of the Walthers 90' TT. The outside split ring is track power. It works by the fingers in the pit contacting the opposite sides of the ring. The gap is the auto reverser. There are 2 other rings and a center disk that all have fingers contacting them all the time. Im not sure what these 3 items do, but if I had to guess, 2 are the motor and 1 is the auto indexing system?</p> <p>The following statement is a WAG and I dont actually know if this will work, use at your own risk:</p> <p>Remove all electronics from the TT. Install the best motor decoder you can find (or maybe a sound one with air pump noises or electric motor sounds). Hard wire the track power for the table into the table motor supply wires. Use the same wires to provide power to the decoder then connect to the turntable motor. Install a DCC Auto Reverser in line with the turntable's new power.</p> <p>Remove all locomotives from layout. Program turntable on main. Use your throttle to spin turntable (slow speed motor control very important).</p> <p>This uses only 2 of the rings on the bottom. You might be able to put some conductive paint across the other ring and use it for something else (lighting on the TT bridge or something).</p> <p>The above is an untested theory. I have not tried it to see if it is practical. I provide no garuntee that this will actually work.. And it definitely voids the warranty.</p> <p> </p>
