I would like to modify a charger that delivers only if “feel” the battery connected. what I need is a voltage present regardless of whether the load is present or not (Battery)
as I identify the section that detects the presence of the battery at the terminals ?
Post references to your charger so you know what we're talking about.
This way it's like asking my car has a problem but you don't specify what car it is, with all the good will it is difficult to be able to help you with the information provided alone
