Ok here is where I am. The unit is a cheap chinese made Chicago Electric/Harbor Freight special 12v 2or6amp charger. I have 25vAC on the secondary of the tx so I believe the tx is ok. From there I have a very small pc board with lots of transistors and resistors which all of them check out fine. Then I have the two (not sure-power fets) bolted to the heatsinks which the tx secondary taps attach to. Every thread I have read seems to target the two chips on the heatsinks. I have one out of the circuit but there are no numbers at all to source out.
Any help in getting this equipment fixed and back to the owner would be greatly appreciated.
