The following has been taken from another (defunct) Forum to preserve it with their permission.
A question was asked about fitting a Loksound XL chip into a Heljan Hymek (though is relevant to most of their 0 gauge locos so far). One suggestion was to mill the chassis to make it all fit properly.
Someone else on a different thread went about replacing the HJ PCB with a replacement that kept the handy little plugs on the wiring and also meant the original PCB could be put back in at a later date.
"I contacted Heljan by e-mail and received a very prompt reply from Kim Nannestad. He attached a diagram on how to modify the PCB, albeit for connecting a Lenz GoldMAXI decoder, but I’m sure we can translate it to a LoksoundXL:"
Looking up the Lenz manual on their website, and comparing it with the LoksoundXL chip, I conclude the following:
Noticing the long-white wire highlighted here, I emailed again to question this as it is not shown on the schematic diagram:
Kim replied saying that “It is important that you follow the picture in stead of the drawing”, and e-mailed a close-up:
I'm not sure about this white wire - it looks as though it is connected to the fan socket to me. Can anyone "read" this better than me?
As requested, here are some photos of the Hymek “stripped bare”, (with the PCB removed)
