I have now had a chance to look under the bonnet of the Auscision 422s. One reason was purely curiosity & the other issue was to determine my next move to get these locos "to talk".
It is a very simple procedure to remove the shell of the loco & Auscision should be applauded for the way in which they have made this operation completely painless. There are no wires connecting the shell to the chassis & no detail items, couplers etc that need to be removed at all in the process. The magic is all down to contact pads on the loco main board & contacts housed within the shell. Just carefully grip the shell & lift off the chassis...easy peasy. With this in mind it is important that the loco shell & chassis are re-mated in the correct orientation as misalignment of these contacts would cause issues.
Upon examination of the internals & speaker enclosures, I have decided to go with the DCC Sound Loksound install on both locos & following a chat with Mike from DCC Sound... have placed & paid for an order for 2 units. He is at this stage awaiting delivery of his 422 units so a complete install & testing regime can be undertaken before release of the finished decoder project to the public. He is quietly confident that the release of the "kit" should occur next week & so i have another week to just admire my two 422s in thier quiet state.
I have included some under the bonnet shots for those interested.
Chassis sans shell
Close up of main board... of interest is the 3 contact pads ( one marked TRWK ) these are the contact pads for the shell "connection"
One of the speaker enclosures...
Chassis & shell side by side
Contact pins visible in the shell...A cordless shell!!!
