Part # 30-121010
Serial # 01122 1122
Dealer 007
Batch # BB0026
Firmware Rev. B2BHEI-A
option B2B WB
date of manuf. 020100
Back when I first got my Syclone running, I found an open ground in the wiring harness at pin D to the knock module, thanks to Jim's help @ PTE. I repaired that, and it still has never gone off. I'm now on another motor and have audible knock, but neither SP, or caspers gauges go off. I have replaced the new knock sensor with another, and have two in series now and still no reading.
I can get both of Caspers units to light/beep if I give a quick intermitent ground at lead C of the knock module, but SP doesn't show it. <a solid ground does absolutely nothing> I have checked with an ohm meter, and the wiring from the Knock sensor <C> to SP <H1> is good, but still no signal. I can beat the living hell outa the motor with a rubber mallet and no ESC signal at SP or Caspers gauges, yet with an ohn meter, I get small voltage readings from the knock sensors.
I am confused and frustrated to say the least. I have replaced the knock module also, and it makes no difference. I anxiously await any suggests you may have to offer. This unit does have the ESC feature, yes????? <it does appear under "all sensors when in SpeedPro, and it's on my record "dash""> And why does a quick pulse ground occasionally read on Caspers gauge, but not a long solid one?
Bottom line, knock sensor works, wiring from knock sensor to knock module is good, and wiring from knock module to FAST is good. There are positive/negative at the knock module also.
Thanks in advance,
