Last night I was tearing my hair out trying to understand how my point indicator LED could be lit whichever direction the point was set. There was a marked difference in light intensity though between the two and so I can only assume that the tortoise’s contacts are a little dodgy and let a little voltage through when there should be none. To try and cure it (and reduce the intensity of the LED in the other position) I’m installing a larger resistor…watch this space.
Today I put together the board protective covers and these now await the installation of velcro.
