Er.... we were busy going through the board and noticed that there was a loose wire on the contactor, this could have been a fire hazard so we initiated an investigation.... found a book , covered in dust lying on top of the electrical box, blew away the dust and discovered that in the hazy day's of your youth, you installed this contactor, any chance that you can pop up here quickly to come and tighten this wire then?

Mike, I have a new fridge mech that comes from Rosh Pinah to service the perishable plant room, like you,Bruce is also Old School, there must be drawings and documents for anything, checks and more checks..... anyhow whilst I stood there this morning, listening to him explaining what the new timer could do, I noticed this old book covered with dust laying on top of the electrical box, opening the first page, two names jumped out at me, Yours and Paul Hills... had a smile on my face recalling all the characters from Town Electric that use to work on the shop equipment, Danny The Greek, Mark Bennett......
Son in law, thanks for showing this small piece of nostalgia. The board you are referring to must be the electrical switchboard in the cage in the outside yard which controlled all of the refrigeration units excluding the butchery units. If I remember correctly, 57 a, b, c & d are your Dairy units along the side wall. I have a feeling that these units are still numbered with 20mm blue "Dymo Tape", either on the lower front of the unit or somewhere on top. Have a look and you might still see them. The units numbered 58 were the old island freezers of which you have replaced with self contained units.
I might be wrong with some of the numbers but all of the refrigeration units in the shop were given specific serial numbers when planning was introduced back in the mid eighties by Neville de Wit.
As to a quick visit, send down your plane or helicopter and we will make a plan and I'll even bring my tools together with your mother in law................
