Re: 70 LT-1 Vacuum Advance Solenoid
Mine is PN DR1114432. I tested the solenoid and without power the metal vacuum tube (one on the right) and the plastic tube (pointing out at 90 gegrees) are connected. With power applied, the metal tube is blocked and both plastic tubes are then connected.
That means if the engine vacuum is applied in the above fashion, it would never reach the distributor. Is this solenoid supplying vacuum to the distributor when energized or with no voltage? The assembly manual shows one leg of the solenoid wiring going to the "TRANS SW. CONN" Which switch is this? Is it on the trans? The other leg goes through the "TCS RELAY" What is the function of this relay? To isolate another switch from the current draw?
Thanks, Paul
