Bachmann Class 03 diesel - Next18 version

Example 1: Bachmann Next18 Class 03 Diesel - simple sound

Kit: MX658 or MS580; YouChoos SugarCube10

Easy install into the Next18 Class 03 diesel from Bachmann - the MX658N18 (or its' successor, the MS580) simply plugs in, and we've removed the factory-supplied speaker mount (designed for a 15x11mm StickyGasket speaker) and put a better SugarCube10 speaker in instead.

Example 2: Adding Stay-Alive to the Next18 Model

Kit: MX658 or MS580; SugarCube9; LifeLink with 3x 470uF Flat Tantalums

Starting at essentially the same point as Example 1 above, the Class 03 model with Next18 interface does provide suitable connection points for stay-alive, so it is just a case of working out what stay-alive will fit in, and where...

Example 2 Example 2

The PCB provides +VE and GROUND solder pads which we connect blue and grey wires to. These are marked as "V+" and "V-"...

Example 2 Example 2

Our LifeLink connection PCB is joined in, and 3 flat 470uF Tantalums are hooked in too.

Example 2 Example 2

Protect both parts with Kapton tape. The Tantalums slide in underneath the motor, and there is a convenient home for the LifeLink just under the top lighting PCB. Secure this with a blob of BlackTack.

Example 3: STACO2A for stay-alive

Kit: MS580/MS590/MX658/MX659, STACO2A

This example shows a STACO2A stay-alive kit used insead - connections from the model's PCB are the same, but we go via the STACO PCB to a pair of mini GoldCaps. The GoldCaps are connected in series, but separately via wires, as one GoldCap will sit each side of the base of the motor - perfect fit!

This approach gives a few seconds of backup power, though charging up fully takes a few seconds too.
