Spent a good part of the afternoon trying to shake out the persistent issues with the 147. Found the problem with charging system - the ground wire on the regulator had a "cold" solder joint. I checked those visually but never measured with the DVM; essentially open circuit. Don't have an iron hot enough to melt solder on the bracket and didn't want to melt the rubber mount using a torch so I made a jumper that's soldered to the regulator base in a pool of solder already there and then a loop connector on the other end so it can be clamped to the chassis frame under the mounting bolt. Put it back on there and started it up, after a slight adjustment it came up to approx 13.75V and held there and didn't vary much with lights off or on. Looks like the ammeter is bad, though, and the glass has a crack. Also the S/G needs bearings. More parts on order this week.
Also tore down the electric lift and put in some bearings and a new seal. Fortunately the gear box and screw tube were full of a brown grease and were protected from the moisture. (The crud and corrosion in the brake compartment was cleaned out earlier and left soaking in PB.) I ordered a snap ring with the parts and am glad I did; the old one gave up instantly. It's laying there on the 'B' in the pic. Need to get a new set of cap screws to finish.

Also ran the sc2400 (technically not a CC but I did buy it at the local CC dealership) to clean up the ice on the drive; tried out the Internet wisdom of using a 1 1/2-inch diameter length of ABS pipe slotted and pressed on to the blade edge. It helps, but isn't as good as I had hoped. Might try a 2-inch pipe.
