a fairground life (ground hog day)

Back in my box again for the last three days. Every day mostly the same. Made some phone calls and sent Blakey some texts, more or less just to agitate him, well idol hands and all that. So at 5pm when the DZ started to play up I wasn't too bothered as it broke up the monotony of the day. The ride was stopping halfway up again. "r" and I checked the brushes (all 24 of them) to no avail, so I sent "r" up the tower to remove the power rail connections and clean them. While he was doing this I noticed that all the bottom and middle rails have connectors at both ends to supply the power, while the top rails only have connectors at the bottom. This seems a bit flimsy and if they corrode the connection weakens, resulting in a power drop under load and in my opinion the computer reads a voltage drop as a zero and interprets that the connection is broken and therefor stops the ride (digital systems work with 1 or 0 = on or off, there is no in between). Right enough after we cleaned the connectors the ride was working again fine. So a job for a little later will be to attach a second set of wires to the top of the rails to add a bit of reliability to the whole operation. Typical manufacturing penny pinching that creates problems far in excess of the costs involved to do the job right in the first place! Bloody accountants!!
