Knock Sensor Light and Alarm problems...

[jkooser at impsat.com]

I just built one and I was able to see the LED blink and the alarm chirp
when I hit the test button.  No ECM, no connections other than a battery
charger for power.  Check your jumpers and make certain they are all
connected correctly.  That was the real tricky part of building the circuit
for me.
