Heljan class 28 8 pin……where’s no’1 pin?

[boxbrownie]

Started fitting a Loksound 5 to my class 28 but having removed the blanking plug there is no indication which is PIN number one on the board, I am guessing it might the pin next to the NMRA logo?  But would prefer to be sure.

Found some information confirming pin one is marked with the NMRA logo, which is ironic as the NMRA standards say it should be marked with a dot or triangle

If lights down work correctly with an 8 pin then the decoder is 180deg wrong and needs turning round.

Everything worked except the motor drove in reverse, soon fixed.
