I’ve built this module and it worked fine, untill i gave it the father inlaw for his model railway. Where can i get a PDF file that gives a description on how every thing supposed to work, I:E all the voltages on pins
Nowhere… The schematic diagram included should be sufficient for that.
Thanks for the reply, BUT what if that diagram is not enough. Rather than go buy another kit when i can just replace parts to get it going again…
Sorry, circuit descriptions/troubleshooting guides are not available.
Can you supply more info regarding the problem?
Most likely, if it worked before and suddenly stopped working, there is a mechanical cause, such as bad or loose soldering, wiring, interruption, etc…
Sorry, this forum does not allow picture uploads
If you can provide LINKS (e.g. by using a free online picture base) to HI-RES and SHARP pics of your assembly (both solder- and component side)
then we can take a look and provide some feedback.
Thanks for the help, but on replacing the lm324 it again works fine. Quick question, is there any way of controlling the MK134 from the track power supply so it is actually in harmony with the train moving I:E when the train moves the sound starts…
