what is this things purpose?

[73 dart custom]

I have a 1973 Dart Custom, 225 /6 automatic. This little silver thing located under the dash on the passenger side gets hot, even with the car off and even when the key is NOT in the ignition switch. I have disconnected the battery until I figure out what is going on. Looked at the wiring diagrams over on MyMopar and I still have no clue.

isn't that the ballast for the map light or under dash courtesy lamp?

Maybe? Don't think the map light is working but haven't found it yet to verify.

it is aluminum and about the size of a condenser. But even if it is a condenser, what is its purpose being under the dash?

Your car is probably equipped with ignition switch light and a couple of others that remain lit for a little bit after opening door. I’m thinking that is a time delay relay. Look under your wiring diagrams and it’s probably under optional lighting. That’s my guess. And yes from what I recall they do get a bit toasty. Usually they are closer to the steering column.

Get your big wallet out .. I found one on e-bay and decided I didn't need an ignition lite.. flashlite is alot cheaper...
