Over the many years, I’ve written articles about the ST head and some of the simple things you need do, one is flip the unit over on it’s back and notice the large open holes under each bell end.
You might not hear it, but these holes are the same as sirens. Do you remember Homer’s account of the sirens that called sailors onto the rocks? Well these holes call field mice, and they find your ST to be a nice and safe home. One of the first things you do is cut metal fabric and wire it in place over these holes. Yes, you should know Murphy by now, and you know he’ll make it happen if you take no precautions.
But let’s add.. some of us who know far better, don’t get around to doing what we should, and I have been so guilty at times… So, I don’t dare poke fun at Dave, as I know I have neglected a good many chores of my own..
Here’s Dave’s Mail:

George: Dead st head after winter setting. Vermon got into doghouse. Moved twice, can’t find cd or wiring diagram for st. Want to check with vom and if necessary flash field. 12v, engine off ok? Point me in the right direction. For the first time in 7 years Lister had air in supply line took 3 bleeds to get it to stay running. When it rains it poors. Good to get fixed before you need it, right? Again 7 years of crank, fire, power, and now this. Thanks, from the 60 + club.
Dave, if the mice stayed in the dog house, that would be a good thing.. where they really like to be is in those bell ends, and of course, where they do the most damage is via their urine and rotting out insulation and converting metals to ooozing piles of oxides. And it’s amazing to see the bits of things they find to drag in for insulation after they strip what they can from the wires.
OK Dave and others.. Here’s an old ST page, with lots of links that should be helpful.
Dave, we’ll all be greatful to know what you find, and I’ll help in any way.. let’s leave bread crums here under comments, so others can follow.
