Thanks for responding so quickly Nicknorman. The batteries have been on charge for three days, the yellow light is flashing indicating in the float phase, the charge current is down to less than 1 amp so I infer that they're as fully charged as this unit can get them (12/800/35 on five 105ah sealed cells) . I cannot work out from the manual which light actually is the "bulk" light. What happens after the five "all three led flashes" is that the green and yellow light come on together for maybe two or three seconds then it goes to yellow only. At which point should I flip the rocker switch to "on" ? Thank you for you patience.

Please can one of you Victron experts help me make my Victron Multiplus equalise. I have mastered the trick of toggling the switch to get all three LEDs flash five times but I can't quite work out at what point to do the final flip to " on" which selects equalise. I have got the "three LEDs five times" ten or more times over the last week and flipped as soon as the green and yellow come on but only on one occasion did the voltage rise to 15.1v which it held for an hour, which is what I expected for equalising, on all the other occasions it went to 14.2v which is forced absorption.
