I gotta tell ya...this Vans Forum is the bomb (as the kids say)!!! I start a "please help me" thread and go to bed and then the next morning there are tons of helpful replies...THANKS!!!

>Do you have the dual crank sensor circuit board? If so I just removed one to upgrade to mini sensor, maybe that would help? I can maybe take photo.

Yes that would be most helpful!!! I need to know the colors of the wires that connect to the PC board.

My unit has the following colors:

Black x 3
Non-insulated X 3
Red
Green
White

If I had a close up of the PC board end I could figure out the channels because there are three wire bundles so I just need to know what channel is the red/green/white.

Dave, your notes show white/blue/green/orange. The numbers you cite are they the number of pin on the 9 pin end or the 15 pin end?

Lightspeed will not provide me with the colors of the wires because he does not condone field connecting the connector ends. He said he would sell me a PC board with wires connected for $487.00 each...I have two.

THANKS everyone for your help

Those are the wires that connect to the 15 pin input connector to the box. If you didn?t disconnect at the crank sensor those would be the colors to hook up to the 15 pin connector. That?s assuming Klaus was consistent with each channel. Worse case would be outputs not corresponding to inputs and as I said before you could swap coax outputs to match a, b, or c firing order. I will check my crank sensor module and get a photo you you.

Bill;
send me your email address and I will send you the schematic I have for the LSE. The schematic shows wires to 8, 4 and 12o'clock as white, blue and red respectively. They go to cyl 1&2, 5&6, 3&4,respectively.

I did not disconnect the crank sensor because I did not want to remove the prop...shoulda...coulda...woulda...Grrrr.

Just curious, what vintage is your Lightspeed III? Mine is a circa 2003 unit. It has red/green/white.

>Worse case would be outputs not corresponding to inputs and as I said before you could swap coax outputs to match a, b, or c firing order.

I am on a trip for two weeks now so I will not be home to play with the airplane until then...unless someone chimes in with some info by then I will have to go that route.

>I will check my crank sensor module and get a photo you you.

Dewey was super nice and tried to send a photo of the sensor end however the silicone sealant on the PC board end made it too opaque to see the colors. If you already pulled off the PC board if you can kindly do a continuity check on yours I would buy you a cyber beer [BEER GLASS CLINKING AND CHUGGING HAPPY FACE EMOTICON ADDED FOR DRAMATIC EMPHASIS]
