i want to test my ignition coil to see if its good or bad, anyone know what the specs should be on a good coil?

its a 94 accord lx, has the tec external coil

and also, how do i test this coil?

thanks

 

section/page 23-103 of the manual that can be downloaded from the DIY section describes the procedure.

 

I don't know the resistances, so check that manual. But resistance is part of the story. Even if it passes the resistance tests, it might still be bad in the sense that it lets spark leak to ground. You can't test for that with a normal multi-meter.

But with an external coil, you can watch for arcing. You want the engine to be completely cold, and complete darkness. Like 3am after it's been parked all evening & night. Open the hood & turn off all the lights. Start the engine & look for any arcing. A dull blue glow means the spark is leaking out from degraded insulation. Glowing plug wires, replace em. Glowing distributor cap, replace it. Glowing coil, replace it.

 

I'm with Jim on this one; seen many coils pass resistance test, yet break down and internally short when under actual electrical load.
So whats the rest of the story, that made you decide to test the coil?

 

thanks guys

but my car wont start, i was thinking bad ignition coil but turns out the timing belt skipped a couple teeth
