Trouble with Rob Paisley's road crossing circuit

I purchased two road crossing PCB from Rob. I assembled the board and the components have been inserted correctly using the correct components. My problem is that that when I switch power on the lights flash for about 3 seconds and then stops. Power supply is 12Vdc. On activating the photoransistors nothing works. Can anyone offer assistance in my problem… At this stage I am not adding any accessories to the unit but may be a Tortoise added at a later date.

Thanks

Give Rob Paisley a call. That would be the sensible thing to do.

I agree. I have two of his boards, one with gates, the other without gates. Both work perfectly. I bought them already built.

I tried to use them with IR detectors for night use. Rob helped me with that. It didn’t actually work. I realized I was actually happy with the visible light detectors.
