Tachometer Wiring 447 SCDL
in 2 Stroke Technical Questions
5 years ago
I have a Rotax 447 with BSOH points ignition I am about to convert to Ducati SCDL. I purchased an early Ducati 447 ignition, and it does not have the grey Tach cable. The Rotax Service Bulletin 7UL 93-E Sept. 1993 has some info. It says between the green ignition cable, you should add a 10k /9w resistor, and the other end should be the gray cable.
My question is, am I correct in my assumption here? I want to use the engine with an AvMap Engibox. The Engibox Manual Reads "EngiBOX applies a 100 ohm load on RPM."
Thank you in advance.
