The voltage meter has been waggling around a lot when revs rise over 4k, then settling down. Charging has been unaffected, so I suspected a dirty connection either at the meter feed or even at the reg-rec (SH-775).
Stuck on another reg-rec and the voltage was fine, no waggling.
Put the original SH-775 back on and ditto.
OK, cleaned up the connectors at the 775, put it back together and that's it sorted, seemingly.
Since I'd got it hot, I checked compression figures...
1. 140+
2. 140+
3. 140+
4. 145+
That do for now.
