This actual simple ambit uses a agent ,two diodes , a capacitor and an ammeter.
To allegation a array aloof affix the + and - terminals of the ambit to the agnate terminals of the battery.
When the array is not charged, the ammeter account shows 1-3 amps.
When the array is absolutely answerable the ammeter reads Aught or about zero, afterwards which the array should be removed from the
charger.
The ambit is a abounding beachcomber rectifier application 2 diodes for rectification. The capacitor is acclimated for smoothing.
I anticipate the ambit works accomplished after the capacitor back the array itself acts a BIG capacitor. But back you are application the
circuit to accumulation 12V (as a array eliminator) the capacitor needs to be present.
Care should be taken NOT to about-face the + and - terminals while abutting it to the battery.
