For various reasons, the last two work parties had to be cancelled. We decided to postpone the one that fell on Mother's Day to the following weekend, but in the event that one had to be cancelled too, so today was our first visit in nearly a month. As Ian's power unit parts have not yet arrived, he, Dave & Pete fitted two cylinder heads. I tidied the elec workbench in the coach and found homes for many items, then wired the first three warning resistors described above.
