1988 Chrysler 5th Avenue 88 5th Ave won't run on its own

The car can not be fixed. I suggest you sell it to me! :)

That was my dream car for many years.

It sounds like you just need to replace the battery or charge it at a slow rate for a couple of hours. When the battery is totally dead, it will need to have voltage applied to it for a while before the acid inside becomes electrically conductive. Until that happens, the battery won't start to recharge.

Once it runs on it's own, measure the voltage across the battery terminals. A cheap digital voltmeter will work fine. You must have between 13.75 and 14.75 volts while the engine is running. If it stays around 12.0 - 12.6 volts, the alternator is not working. This is by far the world's most reliable and easy-to-troubleshoot charging system.
