hi guys,

I need a bit of help - i have the below setup:

- Arduino Mega 2560 (clone)

- Arduino Motor shield

- 12v 2A power for the shield

- 5v 1A for arduino

When i power on the motor shield, on the locomotive i can hear like a screech and it's not finding the address.

i've used the troubleshooting steps:

- i get around 5v vc and 6v ac

- attached the output of the serial monitor

Locomotive is using a Plux 16 decoder.

Thank you

Adrian

Thanks for providing the log. Confirm that the power supply provides DC voltage. Measure the DC voltage of the track power supply. Send the power command <1> and measure DC voltage on each rail vs GND. Should be about 50% of track power supply.

Pins 3, 11 should be 5V DC when power is ON. pins 12, 13 should be 2.5V DC pins 8, 9 should be 0V turn off power <0> power tracks separately and check track voltage again -- this will confirm which output is the programming track
