Tecpro 24v 50A Battery Charger
I have a SM with a Tecpro 24v 50A battery charger. If the battery is low and this charger is switched on, initially the charge current is quite high but very quickly reduces to a trickle.
I wonder if anyone has experience of this? I think it maybe the 'sense' voltage adjustment but I've had a look inside - there are 3 potentiometers but they re nit marked and I don't want to risk damaging the batteries.
Does anyone have any ideas or diagrams please?
