Help with MTH GE Dash-9

This topic has definitely come up before. That clip holds the wiring for the ditch lights in the shell. Remove the shell again, flip upside down. That clip is just there in the recess there at the front.

The exploded diagram does not show that clip. I just know we had that exact engine at the local club and this exact question I know personally that is the location.

Again, the underside of the plastic shell where the front walkway is, the ditch light bulbs go into little holes molded in the shell. This clip was just a way to I guess hold that wiring in place during assembly. Truth is, it's obviously not doing a lot. I mean it did just fall out when you had the shell open so it's not some super secure clip.

#21 is the lenses for those ditch lights under the walkway and handrail.

The ditch lights are the 2 bare bulbs and wires going back to the white socket in the photo below.

#22 is the headlights.

Buzz details in this topic regarding PS1

Does your buzz get louder at high voltages?  Does it go away at track voltage under 9V?  The buzz can be a bad capacitor on the power board.  But a heavy buzz is usually a voltage regulator failure, and your over driving the audio amp/speaker.  G

Vernon--Thank you so much--including the link to the MTH site.  Now that I know where to look, I'm sure that will come in handy.  I've read over the other thread.  I believe the engine was running at between 9 and 12 volts.  I've attached a video of the engine running so you can hear the sound issue.  Thanks again.
