My paralax temp assure was charging water out of one of my batteries this past year. It is a 45 amp converter/charger that tapers the charge based on battery temperature & finally turns off when fully charged.
My question: How would you test the unit if you think it is not performing right?
My multimeter has a max of 10amps for 10 seconds.
I check the batteries today with my load meter (kal resistance meter) and then took them to wally world and they also tested both batteries and pronounced them good. 2 & 3 years old.
I am thinking I will charge the batteries due to being load tested, put them back in the trailer, hook them up, give them time to be fully charged and then hope I don't blow my 10amp meter.
I will then check the charging every 15 minutes until it turns off or it does not turn off. Literature says the total cycle from strong charge to off should not exceed four hours.
Could I get the same results by checking volts and not amps ????? Will the volts taper just as I think the amps will?
Your comments are appreciated. I have to get this thing checked out. Cajun caravan is coming up second week of march.
