- Hi guys new to all this but would appreciate some help. I have set up the charger which has been working fine, when engine on the voltage on the app as input rises 13+ volts and starts bulk charge. It has charged to float on long journeys. But now I have noticed the app stays at 12.2 volts and doesn’t alter at all obviously then it will not charge. I have a monitor and have put a multimeter on the starter battery which displays 13.7 volts but app stays at 12.2 volts? I’m confused as it’s been working fine. Do you think this could be anything to do with the hot weather we are having in the uk, as it’s only done this recently? Any help much appreciated
thanks Dan
