hi all,

i need to test an in circuit scr, its attached to a heat sink. the pcb is a part of a power supply module. the test for an isolated scr didn't give proper results here. and i don't currently have a similar pcb.
 
thanks phil,

i will send you a little more description of the adjoining circuitry too. let me once review the circuit (no schematic).
