Stayed on the visitor mooring at Brewood while I did the first current analyses with the new clamp meter. Initial results show:
a) the alternators produce a charging current even at tick over;
b) minimal difference between 1000, 1200 and 1400 rpm;
c) charging current seems to drop quicker than I'd expected to around 20 amps;
d) inverter's standby current about 2 amps;
e) both TV and fridge take 5 - 6 amps when running, while TV on standby is minimal;
f) the relative currents from the domestic and engine alternators were not what was expected, and will need further investigation. Especially need to check that the domestic one is OK – this is the one whose regulator was changed in April / May last year.
