High beam issues

[Kajjmack]

Hey guys! Been awhile i know. Sorry 

I am having an issues with my wife's 1985 Eagle Sedan.
The high beams turn on just fine but after about 5 mins all lights will shut off and i have to go to low beams to see where I am going.
I have heard it is a ground issue, a switch issue among other things.
Thoughts?

The Eagle headlight switches have a circuit breaker inside (found out after mashing one open)

Try a new headlight switch. they are cheap and available new from a local autoparts store.

Another but a little more expensive and labor intensive option is to install relays and take away the load from the switch. There are already made harness to make it easier or you can make one yourself. Here is some good info if you got a few minutes to read. http://www.danielsternlighting.com/tech/relays/relays.html

I 2X the add relays.  It's fast and simple and eliminates sooooooooo many problems.  Should brighten up the lights too.

That's what my husband did on my SX/4.  He put relays in for each speed on the blower fan as well.

I can't agree more on putting relays in. Your switch breaker is worn out and needs replaced anyway. Besides, any lighting upgrades are putting it near its peak load. Your lights will get brighter and overall it's better for the rest of the electrical system.

I'm also adding relays on the high speed fan terminal in my cars, I've seen a couple of those burned out. The other positions seem to do fine because the resistor limits the current flow.

Just a note, you can buy relays w/ pigtail connectors in bulk for next to nothing.

Not an Eagle, but a '94 Dodge pickup I had. Same problem, turned out to be the headlight switch.
