I have recently purchased a newly released Bachman LMS 10001 locomotive in black and silver.
I now am in the process of fitting a Zimo MX644D decoder with ZS1000ASLsound and a twin 2x4 ohm flat speaker/ Should the speaker leads be soldered to the two tags marked SP+/- on the loco's PCB? The 12 pindecoder can be installed either way up. Is the correct way with the black pin connector block on top as fitted in the photo?
See photos.
Advice would be appreciated.
