Fog lamps - no voltage

I am not getting voltage to either front lamp. Headlights on, low beam, indicator light is on, but no voltage. I surmise the fuse for the lamps is listed as "front lamps" (#15 in manual). 30 amp fuse looks good (rear lamps work, i.e. back-up lights).
Next step suggestion?

I have a green wire with a black stripe & a black wire going to a connector turning into a black wire with a white stripe & a black wire.

Re: Fog lamps - no voltage

Check the fog light relay. Are you measuring across the connector or between the pins and the chassis or battery ground? Only measuring across the connector might be misleading if it's the ground that's bad.

Would Jeep have put in the wiring without a relay?

Re: Fog lamps - no voltage

Got voltage now. Replacing a 15 amp fuse in the engine bay fuse box now gives me 12v.
But if I hook up directly I fear the fuse will blow again (since only 15 amp for both).
Still wondering about that relay, is this it?

Re: Fog lamps - no voltage

But if I have 12V, then the relay is working, yes?
