Look at the plus post on the battery clamp where all the wires come together
if you see black or a burned area, this is possibly where a elec short takes place which activates the juice to the relay box
hope this is a good place to start, usually look in the likeliest of places.
Hope this helps
Follow the wiring harness from your blinker. Disconnect the factory harness from the relay. Replace with the new relay.
The wiring on the back of your 2000 Pontiac alternator consists of a wiring harness. The wiring harness goes to a few relay switch is and regulators.
The horn relay on my 86 was taped to the wiring harness on top of the fuse panel.
Under the dash on the driver side. Follow the wiring harness back from the fuse box. It's about six inches back and is taped on to the wiring harness.
you may have to also upgrade light relay other than relay and plug the wiring will handle it
it's in the wiring harness up front by the radiator core support.
under the hood The wire for the horn is part of the front lights wiring harness. The relay is not under the hood. Please, if someone knows, where is the horn relay?
The relay harness redirects the power. So when you turn on your headlights, the ballast pulls power directly from the battery instead of having to go though the factory wiring of your car. And if your car did not come with hids from the factory, the wiring usually cannot handle the extra power going through the wires. Which could cause them to melt and possibly catch on fire in the worst cases. But even if your car came with hids and your just looking to upgrade or renew the kit. Getting a good relay harness is still better than factory wiring. The better the wiring to the hid ballast the brighter your headlights could be.
check your wiring to selinoid and relay and battery posts also make sure plugs and or wires are good and check the battery
Yes. Check the fuse/relay center under the hood.
Blown fuse.
Try checking the fuse/relay first. If no problem, perform a continuity check between source and destination (harness).
