I need some help wiring my tachometer.
I made a two diode wiring arrangement to provide a signal to the VW
tachometer.
From 3,4 Coil ----|>----
\
-------- To VW Tachometer
/
From 1,2 Coil ----|>----
For diodes (-|>-) I used 1w 12v from Radioshack. I get a ? tachometer
reading with either the 3,4 Coil connected or the 1,2 Coil connected but the
engine won't run with both connected. It appears as if the diodes are
letting some (excitor) signal back the wrong way and causing the wrong coil
to fire (this is only a guess).
Is my circuit correct? What diodes should I be using?
Thanks Larry
