A testlight works like it tells you in the link also. And you should also keep a testlight in your toolbox, it's the best thing to use to troubleshoot the heavier lighting circuits on your truck. The digital meter works best for the computer part of the truck.

Thanks everyone. I ordered the ob1 tester off amazon. Will give it a go in a couple days.
On the rebiuild plugs and cables were redone. Fuel pump as well although the tanks were not. I'll try putting a new fuel filter in there.
Not sure on smog/emissions gear. How do I check that?

Mmmm. Well, you could take photos of your engine compartment, both sides, and the front of the engine.
Plus both fender aprons.
Check for an Air/Smog Pump above your alternator.
Just behind your engine on the Passenger side there should be a Smog/Emissions valve with 2 large and one small hose going to it.
On top, mid way of your Intake back from your Throttle Body, there is a vacuum tree, photo that as well.

Here is a good resource for your 1986;
1986 EVTM - ???Gary's Garagemahal
Go to this link; Start & Ignition - ???Gary's Garagemahal
Scroll down to page #46, left view; Is the EGR Valve Position Sensor & the EGR-Valve below the sensor still attached?
