Hey folks,
I have a need to hunt down a kit or plans or complete working assembly. Reason for this goofy mthod rather than just a simple clamp on inductive pick up:
I have a chassis dyno for motorcycles. Getting access to plug wires is easy on Harleys and import bikes (prior to 1986), but late model sport bikes have so much body work, it can take 30 minutes to get the tank, sidepanels and sometimes airbox removed. Then I sometimes discover the bikes have a coil in cap set up that only allows me a low voltage signal.
I do have the ability to perform the above , but most customers are so cheap, they think that the $30 base dyno run shouldin clude the 1/2 hour to disassemble their bike and the 1/2 hour to reassemble it as well.
So, since I building my own BS2 based interface for the dyno (to include Wideband O2 data logging) I figured I might be able to pick up ignition signal with out removing body work. Sometimes I can see the plug wires with just a little body work removed, but thre is not enough room for the clamp to get in there. Hence the antenna idea.
I like the idea of disassembling a timing light though. Sounds like I would at least get an isolated signal. I'll have to look into that if I can't find an antenna or quick 'wire-wrap' method.
Thanks for any help.
