Judging from what I have been reading, you're going to need this...
Step 1.) Find the instruction book that came with your Multimeter.
Read it and familiarize yourself with how it works and how use it. If
you lost the book or didn’t get one with it, do a Google search on
the web to find the manufacturer’s web site & download a copy of
the manual.
Step 2. ) Make sure that you know what test lead plugs into which
jacks on the Multimeter. There are usually several different jacks on
most Multimeters, and they have different functions. Make sure that
your battery(s) in the Multimeter are good: if you have any doubts,
replace the battery(s).
Step 3.) Once you are sure that the Multimeter is functional and you
have the leads plugged into the jacks for Ohms ( the upside
down “U” symbol), do some simple measurements to make sure
that you know how to use it correctly. Set the switch to the lowest
range and touch the leads together: you should not see “nothing”
but you should see 1.0-0.3 ohms. Measure a 60 watt light bulb: cold
it will measure about 17.5 Ohms. It you measure it while it is hot,
the reading will be greater.
Step 4.) Make several test measurements using the ohms function
and the DC volts function.
Remember all resistance
measurements must be done with the power off the circuit. This
avoids false readings and possible damage to the ohmmeter..
Repeat steps 3 & 4 until you are sure that you can do it without
making any mistakes.
Step 5.) Then see

and carefully study ALL the information under the Heading Chassis
Electrical, Basic Electricity – Understanding & Troubleshooting. There
are 3 sections with the same heading: read all 3 of them.
Step 6.) Apply what you have learned and make the test
measurements using the information in the wiring diagrams.
Here's the stock 86 ignition wiring diagram. Since it is a carb
conversion, the diagram may not apply to your car. For some of
you who have read my negative comments about carb conversions,
now you know the reason why for some of my remarks.

The red/green wire on the coil should have 12 volts anytime the
switch is in the Run or Start position. No 12 volts and the fuse link or
ignition switch are suspect. If there is 12 volts in Run, but not Start,
the fuse link is good and the ignition switch is bad.
