Default capacitor?

Got one on my 88 Ranger 2.3, well had one, the Engine is gone right now, and I have one on my 89 BII with a 2.9.

it use to be in the Dizzy when there was points in the Dizzy.

It's a capacitor. The coil produces a lot of EM and RF noise. That capacitor is there to catch it and keep it out of the engine control wires and radio. The engine will run, usually just fine, without it, but there will be all sorts of noise in the radio.

thanks to all, that is what i thought but haven't seen them for some time. even searched advanced auto for a replacement but there were none. dont think it has anything to do with my current problems of no spark.

No, a bad capacitor won't cause no spark.

I'd be looking at the TFI module.

With the plug in the coil wire plug sitting on a good ground with the key on, jump the neg side of the coil to ground quick touches you should get a brite blue spark. if so coil is good, then you need to troubleshoot the module and the pickup coil in the dizzy. Check all the wires and connectors first. The tech library under TFI diagnostics and a volt meter will get you there just print it out and have at it. I always read it through a couple times so you know how it works to help the diagnostic.

yes, thank you. I have looked at the tfi sheet in the library. the only unclear pt to me is the diagnosis of the pick up coil. can this be done through the spout connector (used for checking timming)? or how? I have tested the tfi's new and old and there connectors for voltage. but the pick up coil is still the gray area in my mind. again thanks oh and how do you replace the pickup coil, been looking all day.

You have to pull the dizzy to replace the coil. You can test it with jumper leads attach male spade connectors to some jumper wires and push them up into the coil using the module as a guide for which one is which. That is also how you can put the remote module setup just jumper wire the coil to the module and mount it on a heat sink similar to one you would find on a computer processor always use heat sink grease when mounting the module. To change the coil you have to remove the cam gear and pull out the shaft easy enough to do with a drift pin and a block of wood tap out the roll pin and if the cam gear is worn this is the time to replace it also. Check the bushings in the dizzy for slop first if there is any slop side to side it can affect the spark and end play can affect the timing and replace the o-ring when putting the dizzy back in. A rebuilt dizzy is a good option and in general the more expensive the module the better it is.

Turn the rotor to where you have a point to reference when you take it out to put it back the same place.
