Coil keeps burning out

I bought an 84 camaro 2.8 about six months ago, Since then I rebuilt the carb, put on a new ignition system, and put on a new starter. Before i did all the work the car ran fine but it needed the tune up. Now it wont start and keeps burning out coils. I rechecked all my wiring and it all seems to be fine. I cant think of anything else that could be wrong except a short. Any ideas???

Re: Coil keeps burning out

I see you havent gotten any suggestions yet?..maybe tell us some more info ..what exactly did you replace when you did the ignition system?.It sounds like you have some wires crossed or missed a few that were supposed to be hooked up?..tell me what does the Olympic edition have that a regular camaro doesnt?

Re: Coil keeps burning out

I put on a new dizzy cap and rotor, ignition molecule, wires+ plugs, and coil. The olympic edition just has the standard v6 in it nothing special. I rechecked my wiring a couple times and i polished the contact points b/c of corruption and they fit up nice.

Re: Coil keeps burning out

When you put the ignition module in ..did you apply the electric grease between the module and distributor base before you installed it?

Re: Coil keeps burning out

I checked the grounds and they were all good. I put on the electrical grease that came with the molecule. I checked the spark and it was still yellow, but when i was cranking I saw a spark jump from the alternator to the fender so I'm not sure what that was all about.

thats an afully big gap to jump,can that even be possible.i mean ur battery terminals are closer together and they dont arch. u would have to pysically complete the circut across the 2.

take a volt meter and unhook the positive batt cable take the neg lead of the volt metter and conect it to the pos side of the battery, then take the positive lead and connect it to the batter cable see if u get a voltage readin with the doors closed and key off.if u get any reading u have a short somewere

oh btw make sure the hood light is off or it will give a reading,

Re: Coil keeps burning out

ok. Ill have to try that tommorow. Im sure it happened because there was two of us that saw it im just not really sure how it happened. Im thinking that something happened with the alternator and maby it shorted out when that spark shot out of it.

I did this test and it said that i had a short. I took apart the ignition and traced all the wires going out of the coil for shorts and the ones plugung into the bottom of the distributor. I didnt find any shorts here so i guess the short has to do with something else.
