OK - I am stumped- Driving Light wiring

[oldcop041]

I have installed several sets of driving lights over the years, but this one has me going.

All of the grounds are good. I have power from the battery to relay #30. Got # 86 going to the switch (middle). Number 85 to ground. Mini tap from inside fuse box to switch (got power there). Have a good ground for the switch. I get no power from # 87 (to the lights).

So - why no power to the lights.

I connected the lights up directly from the battery - they work.

I have checked everything several times. No Luck.

Did you ground the connection to the minitap?

[oldcop041]

Hmm - you got me there. The mini tap (hot) goes to the switch. One of the points on the switch is a ground.

Not sure how to ground the mini tap. I just plugs into the fuse box - and has it's own fuse.

The minitap I installed (NAPA) also had two fuse slots. I didn't work until I installed both a 10 and 7.5 fuse in the tap. Also check the minifuse for power. Might be defective or blown fuse during installation

No grounding needed on the mini add-a-circuit. Sounds like a bad switch maybe? Try taking your 86 wire and applying +12V and see if the relay fires. If the relay fires, you can work back through your switch (check continuity through the switch terminals) and then your mini add-a-circuit tap.

I'll subscribe to your thread and help you along...

Good idea, but I checked it and I do have power to the switch. Not sure of how many volts - my meter is down - just using a test light. Showld be 12V though if I am getting power.

Steve and doublejfj : thanks for the responses!

Doublejfj - I tried a different switch - no help. I have not tried applying 12V to the 86 wire. I will do so tomorrow.

Check all the connections on the relay. Power (verify at the relay with test light) as well as GND (using the test light in the opposite sense, applying 12V to it and grounding it on the 85 terminal) and the feed.

Sounds like you've eliminated your switch, I wouldn't put it past a bad relay or bad connection somewhere.

I'll keep an eye out for you, let us know how it goes!

OK. Will do. I also ran a seperate hot wire for additional 12V outlets. I may pull power off that wire, rather than the mini-tap.

Going out of town tomorrow. May be Sunday before I can get back to the lights.
Thanks again!
