Heljan Hunslett 05 Loksound Micro fitting.

[pauliebanger]

Hi Everyone,

 

Heljan's instructions say that their recently released Hunslet Class 05 model was designed to accept a Loksound Micro with 6 pins. This suggests the decoder should be plugged directly into the socket provided in the upper part of the engine room.

 

Has anyone succeded in fitting a 6 pin Loksound Micro to this model?

 

The length of the allocated space is 33.5mm.

 

The loco PCB is 18mm long and a Lok Micro is 25mm or a tad longer. That gives a minimum overall length of 43mm.

 

How do I get 43mm into a space 33.5mm long?

 

Do I have to take Heljan's suggestion with a pinch of salt or is there a way to make this combo fit, please?

 

Will I need to make any 'modifications' to the model in order to do so?

 

Any help will be much appreciated as Heljan's instructions are silent on this matter.

 

Kind regards,

 

Paul

Well if you don't know..........who will?

Sorry everyone, my mistake.

 

My original post began with a misconception.

 

ESU don't appear to offer a direct-plug 6 pin Lok Micro. The connector is at the end of a harness, so my arithmetic is irrelevant.

 

This strongly suggests that the decoder is not intended to fit in the engine room with the DCC connector, but to go inside the cab with the speaker.

 

Kind regards,

Hmmmmmm, I murmur whilst scratching my chin and gazing skywards.

Moving the connector to the cab may be difficult. (At least on mine it would be) There's not enough length on the Blue, Yellow and Green wires that connect to the front lamp LEDs.

Also the motor supply wires look like they'll need to be lengthened.

 

Looking at the wiring it doesn't l    k to big of a job to swop the front and rear lamp wiring at their respective PCBs but the motor wiring looks like it'll still be short.

A Zimo 20x11x4mm looks like it'll just fit without any modification.

I think this means you have to deal with the metal work on the weight on the chassis for the cables to run through - I have a similar Zimo 03 project which I was going to fit in my 05  but had hoped would be a quick job so was abandoned to the "to do" pile when I came across this problem

Thanks Guys,

 

I was intrigued by Heljan's claim that it was 'designed to accept an ESU 6-pin Micro sound decoder' but I have been unable to find any design feature or modification to justify this claim.

 

No special provision for the decoder, a channel for cab location without sufficient room to accomodate the wiring (as noted by Chris), and a circular depression in the floor when the ESU Micro comes with a 16 x 12mm speaker in an enclosure. 

 

They seem to have inadvertantly overlooked the advantages of a ZIMO MX648. Lol

 

I now have a ZIMO solution up and running. I did not replace the Heljan wiring and I did not modify the body or chassis in any way but I did fit the decoder within the engine room and improve on the lighting control offered by Heljan.

 

Kind regards,

 

Paul

Chris, I have a problem with piles, too. Every project I start increases them - to do, next week, wait for a part, decoder too small/big/wide, etc., etc.

Oh yippee, looks as though I'll be able to send my 05 to Jeremy at DigiTrains for him to work some more wonders

Paul is it possible to share your solution inc pictures please

Have sent Jeremy a email but be nice to see it in pictoral form as well

Thank you
