Wondering if there is a way to see if pony coils are good without running the pony engine? Is there some test you can do? Also how about checking condensors?

Thanks,

Mark, there is no fool proof way, but the best way I have found is to use your nose, if they smell burnt they probably are.
~As far as resistance values go, I don�t have exact figures & even if I did there are some different coils & aftermarket coils so they might not be valid. I can give you some general values & if they are way out of whack with those you can assume there is a coil problem. On the coil�s primary [measured between the coil�s power wire & the one going to the points set [everything disconnected], you should be somewhere between .5 ohms & 3 ohms [give or take a little]. On the secondary [measured between the 2 plug wire towers] you should probably be between 5K ohms & 20K ohms [if you aren�t at least in the K range suspect burnt up coils].
~On the condensers about all you can do is measure between the lead & case to see if they are shorted [that should show open on a good condenser ] & depending on your voltmeter you can try to charge them with your volt meter then reverse the leads & see if you can read a charge. ~If you are fighting a �no spark� condition make sure you have power to the pony distributor power in post & that power is getting to the coils. Then if there is any rust on the coil�s core remove the core & clean the rust off. If at any time you left the pony ignition switch on for more than couple of minutes without the pony running, suspect burnt up coils [you should be able to smell them]��..
