Electrical help

Hi, and welcome to the site.

First thing is thankyou for starting with the vehical and year, many people who have been on this site for years forget that!

Go to mymopar.com and download your cars Factory service manual, wiring diagram, parts book. All free pdf downloads.

Second go to Classic Car Wiring . Com : Home of the original color laminated classic car wiring diagram
and for about 20.00 get an 11x17 laminated colored wiring diagram.

Many of the diagrams are not 100% correct, (even the OEM have been know to have inaccuracies)

As for your particular issue, did your friend mess around under the dash and in the engine campartment?

There are the bulkhead connectors which are natirious for bad connections, they may have been bumped.

The description sound like blown fuses but who knows.

Too many possibilities when friends "help"

After you get your wiring diagrams start tracing out wires looking for where there should be power when the key is in the on and run positions.

Good luck
