To all that were kind enough to respond to my plea for help, I have studied and restudied the information supplied by 4QD and on their web site but find there are a few areas where I still would appreciate a little help if you could be so kind………… My understanding and assumptions are as follows :-
1) If I am using 2 x12v batteries then the lead that connects the two together is broken by the main isolator that is placed conveniently at the rear of the cab.
2) A lead is taken from the negative terminal on the first battery to the terminal B- on the control unit with another lead from the same battery terminal going to the connection marked 4NC on the HRB wiring diagram.
3) The positive terminal on the other battery is wired directly to terminal 4NO on the HRB diagram.
4) A second wire from the positive terminal on the first battery is taken to terminal 3NO on the HRB board via an auxillary fuse.
5) The wiring for the horns is from connections 1NC and 1CO plus 2NC and 2NO respectively on the HRB board. Would I need to fit what I think are the catching diodes to these connections using connector blocks or are they fitted to the terminals on the horns themselves ?
6) Regarding the motors ( I am running 4 ) do I literally join all the 'positve' and all the 'negative' wires together in order to connect them to the single terminals on the DNO control unit, and at what point would they be joined? Am I OK to run the twisted motor wires alongside each other along the chassis to the controller?
7) Included with the noise suppresion kit is a red transient suppressor, do I need to fit this and if so do I simply fit it using a connector block?
8) Batteries…. can you recomend suitable batteries and would a simple trickle charging system be OK to keep the batteries charged?
I look forward to you replies and comments in order that I can complete the loco for my Thai grandson to use on the 5" track that I have constructed.
Appreciatively, Colin
