Hello, everyone. I'm new to this particular Jeep forum.

I have and 89 Jeep Cherokee that's had some modifications from a few previous owners. I'm learning about fixing vehicles as I encounter the quirks on this one.

There's a weird issue where the radio shuts off when the headlights are turned on. It immediately turns back on when the headlights are turned off. The issue actually resolved itself for a short while and then started occurring again. The stereo itself is aftermarket.

It wasn't very high on my list of priorities until last week when the turn signals started doing the same thing. Only working when the headlights are off. This has now gone from a convenience issue to a safety issue.

This will be my first foray into electrical issues on the Jeep, so forgive me if I need to ask for clarification. I've got a multimeter and plenty of tools (and wiring) available to fix this issue, I just have no clue where to even start looking.

Sounds like a ground issue, here's the link to a cheap FSM with the wiring diagrams if you don't already have one.

Somebody probably hacked a different radio into it....

That FSM for $7.95 in pdf. format is an excellent buy everyone should own.

Are they the real thing in PDF form? Or abbreviated / summarized?

I have paper version for my 91 but would like to own electronic versions of the real thing
