Battery R/C for the Bachmann Climax take 4.

I recently installed another RCS battery R/C and MyLocosound in a new version Bachmann Fn3 Climax. This is the 4th version of how I did it.
I have done a few of these excellent locos since they came out. This is the is just the second one where I have been able to have everything on board.
There is no chopping and cutting of bodywork or changes to the existing Bachmann wiring.
The secret is fitting the Li-Ion battery pack up in the roof. Once again, the Australian Sanyo distributors made me a special 2 part 4s 1700 mah Li-Ion pack with wiring between two parts, so they could fit up under the Climax roof.
The Bachmann Plug'N'Play socket is featured as the easiest way of wiring the loco.

The specially made pack fits neatly either side of the ventilation hatch in the roof.

It looks like this when mounted correctly.

The packs need to be placed as shown so they clear most of the Bachmann Cab fittings.
The red cable above plugs into the JST in line socket shown in the next pic.
Once the roof is replaced, the cabling is virtually invisible.
The slide switch was glued under the rear edge of the cab roof and is easily operated by large fingers.

A small decorative component needs to be removed to clear the battery packs when re-fitting the roof.

The Red power cable runs under then cab floor and then up into the tender comportment. Black heat shrink disguises the cable.

The stock dummy PnP plug is removed and will be replaced with the # Battery-PNP kit.
In between the PnP socket rows there is enough room to mount the # MRW-SSTS sound trigger card.
There is only one wire added to the stock circuit card, That is the the sound system chuff wire to pin # J1-5

Remove the 4 x pcb supports in the coal cover,

A styrene sheet is cut to size to fit under the coal load,
The various components are mounted to the styrene sheet.

The styrene sheet with components is mounted in the coal load with thin double stick foam tape.
The main # Battery-PNP plug is almost shown on the above pic..
The Fosworks RCS OMEGA-10 is exactly the same size as the Centre OFF COBRA-260, so can be used for Low OFF control.

The # BATTERY-PNP kit is an integral part of using this method of converting the Climax to battery R/C.

The kit uses correctly colour coded wires for a Bachmann installation. It saves a lot of wiring.
Aristocraft locos got the socket wiring back to front so they need swapping around.
