They did put a letter in with some of the kits telling the builder that the transformer was slightly different. I have a copy of that letter which was included with the manual of some of the SB-630 units. The letter indicates the wire colors that you have.</span></div><div></div><div> </div><div class="signature">Glen, K9STH

I rechecked the Timer Switch wiring, all correct. So, when the switch is VISUAL, we get the IDENTIFY lights and the Reset doesn't turn them off, just like before.<div id="yui_3_16_0_1_1447618102854_3491"><br></div><div id="yui_3_16_0_1_1447618102854_3492">There is something odd with T3, the power transformer: in the Manual, there are two Black primary wires passed through Grommet F in the chassis. In my chassis, there are TWO twisted pairs through F - a Black-Red pair and a Black-Green pair. These pairs are soldered to the correct numbered pins of the terminal strip. The T3 p/n is the correct Heath p/n too, so what's with this? The schematic shows no Red or Green primary wires on T3.</div><div id="yui_3_16_0_1_1447618102854_3493"><br></div><div id="yui_3_16_0_1_1447618102854_3494">This sure is puzzling.</div><div id="yui_3_16_0_1_1447618102854_3495"><br></div></div></div> </div> </div> </div></body></html>
