[Accrs-ho] Last Friday night at the club

[ACCRS HO Scale]

Climb under the layout next to right side of dispatch. Along the wall under
Oildale is a bunch of Chubb boards. These boards should be lighting up when
a train is detected. If not, well then we know we have a much bigger
problem.
If they are lighting ok, then from each board they all feed into a relay
that provides the flashing signal to dispatch. 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.
It should be clicking away, if it's not clicking then it probably finally
died. I think its been on its last legs for awhile, which is probably why
it gets fussy like this.
You could also just wire around the relay board in a pinch. It just
provides flashing, and as far as I can tell the system should work without
it, just a steady "on" light.
