[Accrs-ho] Last Friday night at the club

[ACCRS HO Scale]

I agree with Joel. I have found especially when it is cold the relay seems to get stuck a bit. If you listen closely there is a ticking sound. I have found it to be very quiet. If you give it a little flick the sound gets louder and the lights start flashing. I'm guessing we just need a new relay.

It's a little board to the left of the Chubb boards that looks like a smaller version of a Chubb board. That relay board is what keeps causing the system to go out. Usually after i disconnect and reconnect it a few times it comes back.

Not being an electrical whizz-bang, I don’t have a clue as what component caused the problem.  Garran thought it might be a relay, but then the question was “do we have any spares”?  Bottom line is that we need someone with knowledge about the system to troubleshoot it and get it back on line.  Do we have any volunteers?  It’s surprising how difficult it is to dispatch trains blind!
