1.1 Diode "Tie Back" missing causes Driver Board transistor Q20 to fail
Similar to the common problem that Star Trek: The Next Generation owners encounter, Terminator 2 can lose the "diode tieback" connection, causing Q20 to fail, as pictured on the right.
Without this "diode tieback", Q20 on the driver board WILL be damaged and the associated coil is likely to become locked on and melt. The diode tie-back wire is violet/orange and connects from the coil power side on the drop target assembly coil lug to J122 pin 9 on the driver board. If the solder connection at the coil lug is solid, suspect the wire connection at the J122 IDC connector. Repinning this connection with a good quality crimp-on Trifurcon pin is advised.
