| + | [title] Determine all 4 PCB contacts for charging post |
| [* black] With a multimeter, test all 3 PCB contacts to determine which are positive, negative and ground. Similarly, ascertain each terminal of your "new" charger port and its corresponding PCB contact. Your "new" port can be a brand-new, identical replacement or a salvaged one of approximate size, post thickness and terminal orientation. | |
| [* black] Unless an identical part replacement, you may have to bend your ports terminals in order to make proper contact and'or enlarge the panel opening for the AC plug as I did. To avoid repeat part failure, I hot-glued my charger port onto my PCB after reinforcing my port's terminals with thicker wire and generous solder. |
