Link 20 confusion.
Aargh. I have two lifeline GPL27T batteries crosslinked in parallel, with a third something separate. There is a link 20, a starter switch thing that says on or off, a combiner switch, and a separate switch that says Bank 1, 2 ,3.
Now looking at the link manual it implies it runs two banks the usual house and start. It also by default assumes 2 x 100 so sets capacity at 200.
However on the panel it refers to battery one and battery 2. No mention of banks. However I assume it means bank by battery.
While having work done various switches appear to have been impacted by big feet leading to two yellow lights suggesting shortage.
Now having put the things on a battery charger I note that when it is on one of the parallel connected house batteries it reads 14.2 volts on battery 1 and 2. That suggests both are getting that charging current, as when charging stops it drops. But since I am not charging the starter bank so far as I know that means battery 1 and battery 2 refer to the house batteries not banks. . So how then would I monitor the other banK?
I found that the capacity was set for bank 1 which drains with the stereo on to 100 amp hrs not 200 and therefore is house?? I also found that the battery type F10 1 = wet 2 =gel was set to one. If the house bank is these batteries ie AMD are they gel or acid or specifically as which are they regarded? I know there is a difference in how the acid is held but given a choice of two which are they? The same choice applies to my battery charger.
I tried resetting the amp hours to 200 but am now getting a flashing red light despite approx 2 hours of motoring at 75 amps and 13 hours on the charger at 8 amps now auto reduced to about 4. Changing back to 100 doesn/t effect this.
I would have thought there were two banks each of which had their charge status shown. albeit as a notional battery. The starter on dial was only connected to the starter bank, unless the all switch was used. However I have found at times if the other 3 way switch is on 2 , the motor won't crank unless I switch to position 1.
I have a suspicion one of the house batteries may be then acting as starter.
In other words maybe there is a dog's breakfast.
Currently all 3 batteries show about 12.4. Would a need to clean all terminals effect things? I found on the delivery trip that all 3 negative terminals were loose.
Okay my physics was a long time ago. I am installing a windlass. Does this go to the starter battery?
I suspect I may need an electrician in - the PO did some of the wiring but before I spend another boat dollar or two maybe on new batteries is anyone with a few clues able to explain this in simple terms? Thanks in advance.
