I am electical stoooopid.... Please help.

I have attempted to install a couple of pairs of KC hiLites... The instructions seemed pretty straight forward and everything was provided. 2 lights are grounded then tied in the same line to the switch. The switch is grounded and a line with a fuse hooked to the battery. Seemed easy enough and the installation went quick... However, the lights don't come on!!!! What am I missing? The switch lights when I turn it on, but no lights. It seems like maybe a ground issue, but I put the ground wire on the bolt that holds the light. I figured that my big 'ole metal bumper bolted directly to the frame would be gound enough. Could it be the paint on the bumper causing the problem or am I looking in the wrong place? Help a stoopid hillbilly out!

Thanks.

def could be the ground, a easy way to check is move the gound, you can use a temp wire to put it to the neg of the battery.

Bad ground is just as bad as a bad power source. Electricity must complete the circuit. Start with the ground side and see what happens.

my experience with trouble shooting electrical gremlins tells me that if your switch lights up then your switch is not only getting power but is grounded well. I would check the ground for the lights, if you are tying the ground for both lights together then you are gonna need a really pure ground. Try the temp wire to the neg. of the battery if that solves your problem I would use a seperate ground for each light. Im assuming your using a properly rated switch (Im not familiar with what KC provides) from the lack of a relay. To answer your other question, it could absolutely be the paint on the bumper. I have had a nice strong ground crap out on me over time due to rust build up, good ground connections can sometimes be really tempramental like that. good luck with your troubleshooting.

step 1, buy voltmeter.
step 2, use voltmeter.
step 3, fix problem identified by voltmeter.

Seriously, even if you're e-tarded, you can figure out how to use a $10 home-depot voltmeter. It'll probably even have a continuity setting, so you can confirm whether the ground is actually grounded. Best $10 you'll ever spend.

Thats the truth, but really buy more than a $10 meter. I have a $150 snap on for work, at home a $30 craftsman does the job for me. Any cheaper in quality and i wouldn't trust it. Cheap one will probably get you the info you need to know for a simple issue like that however..

Learning how to use a meter will make your e-knowledge jump lightyears.

I've got a $150 digital with the AC induction clamp, but not everyone needs to know RMS. I was on vacation in WA once, and my Truck wouldn't start. I ducked into the closest big-box store, and grabbed this exact meter which was on sale for $14.99. I prefer my fluke when given the choice, but this is more than enough for the OP.

Edit: If it's not clear enough, I have to agree with you that the high mid-range meters are well worth the price. Just not for everyone.

What.....the tongue on 9volt method doesn't work?...........what about pissing on the electric fence method?.....both produce results, one just a bit more memorable than the other....

you can touch the power wire coming from the battery to the switch to the power wire going to your lights to make sure you got the switch wired right. If that doesnt work then check the grounds obviously.

I see where you said that you have supplied power to the switch. But did you supply power to the relay for the lights?

well you cant rally mess up kc lights, they come all pre wired, so im guessing your ground is bad, tou said they are grounded to the bumper but most bumpers are painted and you wouldnt get a good ground, try moving the ground wires, you might need to extend them to make them reach a good ground, good luck. let us know how it works out

Thanks guys! It was a grounding issue. I guess that the powder coating on the bumper was my problem. I moved the ground to the bumper mounting bolts and all is good.

Thanks again!

Glad to hear you got it straightened out. Stuff like lightning isnt as complicated as most people think. They just get intimidated because they havent done it before. Read around on forums like this and youll learn all about wiring up accessories. Thats how I leared some basics several years ago when i was an "electrial stoooopid" too
