Electrical problem
1989 Geo Spectrum 4 cyl Front Wheel Drive Manual 126, 00 miles

How do you check the primary and secondary ignition coil's on my car?
We have the ignition coil out, and we are only able to get one reading, coming out at around 3 or 4, opposed to what it should be around 9K right?
