a fairground life

Again up and away for 9am. I took the tyre to get the disc swapped over. While that was being done I nipped away for more aluminium paint then picked up some bulbs for the top of the Tempest. The sun was splitting the sky today and we started on the top lights of the skydiver ride. Already the day started bad, the running light box was frozen on with all lights illuminated at once. "r" opened it up and spotted a blown triac. I had none spare so nipped away to RS components to get some. Meanwhile "r" painted the rest of the floor. I came back with the triacs and promptly fitted one. We put the power on again to try it out----NOTHING,NIL,NADA,ZERO,ZILCH not even a flicker. For the last 27 years I have patched this thing up and kept it going, but today after 6 solid hours it's got me beat. There is power in, the transformer rectifier is producing 12v DC for the logic controller, there is no visible signs of any damage. I even tried a spare set of EPROMS I had. Looks like I bought those new bulbs in vain. Maybe the tooth fairy will fix it tonight?

"r" put on the lorry tyre and did numerous other small jobs while I was tinkering inside the RL box. At 8:40pm we headed home and put out the ad billboards en route.
