Hab battery showing 12.3v so not good and needs charging, connect to EHU and battery goes up to 13.6v but only .6 amps charging rate, leave overnight but next day it still only shows 13.6v and .6 amps charging. Now thinking the battery is not getting charge so I take the PSU out to have a look at the battery charger and that is on green indicating just a float charge going in and if I turn off the charger the battery then goes back to 12.3 v which again indicates that the battery is indeed not receiving and charge. I then have a poke prod and wiggle of all the plugs on the PSU then it starts charging and settles around 14v and 8 Amps. Do you think this points the plug that goes from the PSU down to the battery being the problem?
