HeyObie said: (quoted from post at 15:57:39 11/21/12) Well, I got it all hooked up with the new coil. Ground runs from coil to LEFT side of resistor. RIGHT side of resistor is grounded.
My red bellied baby will not start. I find no spark at the plugs.
I took my analog meter to the resistor. The RIGHT side of the resistor to the negative battery terminal reads a tad over 6 volts. The LEFT side of the resistor to the negative battery terminal reads a little under 4 volts.
Not sure where to go from here. Not sure the the EI will fire at 4 volts. This may be why the guy before bypassed the resistor and grounded straight to the engine block.
Any thoughts appreciated.
OK, first, what the devil are you doing referencing all your voltage measurements to the negative side of the battery in a POSITIVE GROUND system???!! You should always (almost) reference to the tractor chassis, which in your case is the POSITIVE battery terminal. So now that I have un-wound your convoluted measurements, they look OK. A nominal 4 amps thru coil. 4 volts across coil and 2 volts across resistor. That means module is "ON" (as if it were points closed). So that means it is OK or that module is internally shorted, or you created a pigtail short when you installed your new coil.
Check for that short first. Next, with meter from chassis gnd (batt pos) to LEFT of resistor, key on, crank over watching for meter movement as module switched 'on' -'off' -'on'. What do you see?
