Engine: MTH 30-1220-1 RailKing 2-6-6-6 Steam Engine: BCR equipped
DCS Operations: TIU/Remote version 6.10
Track Voltage: 18V
Issue: When operating my MTH 30-1220-1 RailKing 2-6-6-6 Steam Engine the engine lighting is dimmed when the smoke unit is operating.
The light on the front Cattlecatcher and the Firebox lights are controlled by the LIN option on the DCS remote. The "Headlight" is inside the boiler shell and lights the marker lights. The "Headlight" is not controlled by any options on the DCS remote.
At startup with the LIN option "ON" the lights are all bright with the Smoke Unit operating. The lights pulse slightly with the chuff of the smoke unit. When I turn the Smoke Unit "OFF", the lights are bright and the pulsing stops.
When the engine starts moving and with LIN "ON" and the Smoke Unit "ON", the Cattlecatcher and Firebox lights begin to dim and by 6 or 7 feet of movement they are barely visable. If I turn LIN "OFF" the lights are still dim but brighter than with LIN "ON". The "Headlight" seems to be affected only slightly.
When I turn the Smoke unit "OFF" while the engine is moving, the lights are back to bright.
I have taken the shell off the tender and off the engine looking for loose wires, signs of electrical shorting, and have found nothing. I tightened all the wire nuts that I found. I also ran the engine and tender without the shells looking for any signs of electrical shorts and found nothing.
The wick in the Smoke Unit looks "normal". It is white and is not black and hard. The Smoke Unit works well.
Anyone have any idea why my lights are dimming when the engine is moving and the Smoke Unit is operating.
