Bought new off road lights Friday from Harbor freight and installed them tonight. Finally got everything bolted on and wired and nothing. I checked the fuse and it's OK all of the grounds are attached the only thing I didn't do was ground the switch itself. Will this cause the lights to not work?

Any help would be appreciated

 

How do you have them wired directly from the battery fuse switch and lights or are you splicing into anything

 

from the switch one wire to battery with a 20 amp blade fuse. then one to lights with a jumper wire in between and both lights grounded individually. Im wondering if my grounds there are no good.

 

a test light is your friend !!

switch should only need ground if it has a light in it itself

run a temporary ground back from each light to the battery , will test your ground

 

Chances are you don't have a good ground. You should really look into using a relay.

 

Thanks for the help. I'll try a different ground when I get home. That's what I was thinking was the issue.
rexmburns I've never ran a relay on any before so I don't know how to go about wiring one into the system.
