The Zimo decoder arrived in the post yesterday so I thought today I would share the "straight forward " install with you.On stripping down the brass Pug, it became apparent that there's not much room at all, in fact non inside the boiler to house the decoder.:evil: smoke box end has a small amount of space but no decoder or speaker will fit in there These are my chosen item. I can highly recommend the super capacitors and speakers from YouChoos, most of my stock has them fitted and the improved running is well worth the extra cost So the only place available for the decoder is inside the cab on the rear wall. The wires are split into the required looms. Blue and grey for the super capacitor, Speaker wires, motor and track pickup wires in the heat shrink to the right and for the time being the lighting function wires will be cut short and sleeved in heat shrink as I'm not sure I will be fitting lights to this model....but you never know ... side shot showing the heat shrink across the cab door First drilling / cutting job was to drill a small hole for the capacitor wires to go into the coal bunker, plus adding a sleeve Wires now in the bunker capacitor just about fits in height, I will be able to drop it down a couple of mill once the two tags are bent over The only option I could see for the speaker was this area between the axles, as there is a nice flat surface to mount the speaker on to and it finishes flush with the under side so should not cause any running problems Speaker installed Next cut a slot out of the brass inner frame to allow the main wiring loom access to the boiler Capacitor soldered up and then I bent the two tags flat before insulating the whole lot and dropping it into the bunker Blue wire (+) will not be soldered until the decoder has been tested, programmed. If you solder it up at this point you will have trouble programming the decoder so I normally put a small plug on the wire so that the capacitor can be disconnected when ever I need to adjust cv's, but as there's not alot of room on this install it will be soldered at the end By making a slot and not a hole to pass the wire through, it gives you bit more wire length to work on the model. First attempt at reassembling the model proved that I needed to extend the motor wires by 25-30mm. The two purple wires are the speaker cables which again where lengthened. model re assembled, showing the decoder and the two sleeved wiring looms Out with the black paint. The coal bunkers will have a card top with coal added so that will hide the capacitor With the roof on and viewed from normal distance I don't think its to obvious. Once the model is weathered and a crew added I think I can hide the wiring looms as well. Apart from adjusting a few cv's she ran beautifully first go. The capacitor gives approx 3 seconds of power with the sound on, when removed from the track work. I will get a video up in the next week or so.
