I f*in hate this car.

what everyone has failed to mention here is the library,
since they are free all you need is a pad and pen and you can
go pull a repair manual and write down the testing procedures
and even see photos of the procedure itself in some of them.

another thing you will learn to with old mopar products
especially cars with electronic igntions is to carry an extra ballast
and ECU.
personally i make trips to my local U-Pull it auto yard and look for
everything older that is a chrysler product, i have grabbed ECUs
and ballast's for as little as $5 for a pair and ignition coils for $2
so that is another possible for someone on a tight budget.

and one other thing i see no one has mentioned yet is the body plug,
i dont know if the 76 has it but the earler models had a fusible link
off of the starter relay and where that entered the body plug it would
become corroded causing an intermintant no power problem to the ignition
switch. It took me about a week of testing to find that one on one of my
old mopigs and i ended up replacing it with a new style fusible link with
replacable fuse and also cleaned all of the corrosion out of the body plug
and put it back together with dilectric grease and never had another
problem.
