The KAT1 in my K1 has stopped working. A data stream appears on Pin3 of the U1 PIC16C72 but I don't hear any relay activity or see any relay driver outputs going high. The 6R/AUX lines does go low when I attempt to activate the KAT1, but that is the only observed reaction. Does any body have a sample timing diagram of the Pin 3 input? I am seeing a pattern with a high for about 10ms, low for about 30ms, high for about 40ms, low for about 40ms, high for about 10ms, low for about 10ms, high again for about 40ms and so on. Does anyone know if this sounds wrong or if the PIC has just expired.
