I am upgrading my MTH UP 844 from ps2 to ps3. The ps2 5v board burned out.
Can anyone answer some questions I have.
This engine has the following lights
- cab light.
- green marker LEDS in the engine.
- backup lamp in the tender.
- backup lamp in the engine.
The ps3 steam upgrade kit only has a connector for headlight, backup light and marker LEDS for the tender. I will use the green Marker LEDS in the engine. The tender has no marker lamps.
Can the cab and firebox lamps be used? If yes, what do I connect them to?
Can the original lamps for headlight and backup light in the engine be used on the ps3 upgrade board instead of the ones in the kit?
Can the ps3 upgrade board drive more than one lamp in parallel? If yes, how many can it drive? I want to put the backup lamp in the engine and tender in parallel and don't want to overload the circuit.
On the ps2 production board the orange wire on pin 3 of the 12 pin connector drove the firebox and cab lights. The ps3 steam upgrade kit has no connection on pin 3.
