How to connect 12 v 3 pin horn relay - Cars & Trucks


The horn and relay is the most common formSignal is set iron anodeGeneral on the relayauto diagnostic tool ... Cars & Trucks

Relay The horn relay is bad on my Montero sport..... They cost $50.. I just don't have that right now, I have to get car inspected... I have another relay with the same type terminals... I need to know if I can use it... It is 12v just not sure the amps. I know my horn only pulls 10a..my horn will blow when this one is plugged in... as long as it is the same configuration and definitely cant pull more amps... will it work?????


If the internal configuration is the same, the amount of amps is not really important. The horn would only draw current when in use which would be for a few seconds. ... 2000 Mitsubishi Montero Sport

1993 Volvo 940-T, the horn does not work, I have removed the horns and they work when connected directly to 12 volt source. When connected to the car leads they do not work in spite of getting voltage at the connectors. Where is the horn relay? Could this be the problem or what else is there. They do work intermittently but I need more than that. Thanks, Bill

1997 dodge dakota i believe there is no power to the ecm the ignition "key cylinder" was ripped out before i bought the car i've used a hook to start the truck for about a year. i was told the power for the ecm comes from the ignition switch. there is no power to the fuel pump the spark plugs i switched all the relays around into the horn and horn worked with all of them i'm assuming that the relays are good. could not find a fuse link. bought a new ecm when i wiggle the plug


Hello there are several ways to check these problems one way is to look at the ecm terminals and see if they are bent or damaged also if you live in a major city most large librarys have mitchell and motor manuals that will have the diagrams you need ... Dodge Dakota

I installing a high output altentor in truck. I have a beuler 12v 40/60 amp relay how does this get connected. I see the male and female connector in back of altenator, but have 4 additional wires. 2 wires (close to the male connector) are together with a terminal end. Does that go on the charge lead off of the altenator? THen I have a white & read wire, what are they for and how are they connected.


I can't believe that you have been supplied a relay for a high output alternator.A 40/60 relay can handle up to 60 amps,a high output alternator would blow that up as soon it has it work hard.The relay has to be for the field terminal which will neve ... 2004 Dodge Ram 2500

Ford Focus 1.6 Zetec 57 plate.The alarm starts going off when the car has been locked for a bit. The Horn Blower relay is pulling in and out and "something" to the front low side of engine appears to be trying to open (clicking). The Rear heater switch light was flickering on/off and left indicator direction arrow was flashing. When engine was running everything appeared normal. I suspected fuse might have gone and there may be seperate power and control fuses. I pulled the 25 amp horn fuse.

F-250 Super Duty 7.3l diesel. Truck wont start. Just clicks at starter and then dash lights and all relays flash off and on constantly. When I disconect the two batteries, I get a big spark like there is a major power draw. Any hints as where to start? Also, this happened after one of the batteries went dead and a charger was connected to the battery to start the truck (on 50 amp start mode).


Is there a security system from the factory on it if so if so just try using your key in the drivers door and unlock it with th key ... 2001 Ford F250 Super Duty Super Cab

Hello Hope you all doing well... My car is Alero 2000 stopped suddenly at the road, I took it pushing to my home :(( I thought the problem with fuel pump, coz there is no fuel coming to the engine, but when i gave the fuel pump 12V directly from the battery I found it working! I checked the fuse board, I found fuse # 48 fired, i changed but still not working Also i changed relay # 18 with the relay of the horn but still the same, no change, fuel pump does not work when I connect it in his place


You will need to trace the wiring to the pump and look for an open or short. I had one where the connector from the pump to the wiring harness (near the RR wheel) had a loose ground connection. The only way I found it was to move the cable and when ... 2000 Oldsmobile Alero

2003 Hyundai Tiburon. The horn will start blowing when the car is parked and turned off. The only way to get it ti stop is remover the horn relay. Switched horn relay other relays in relay box but the problem did not move with the relay. It stayed with the horn. After about 2 hours can reinstall the horn relay and the car is ok. But this is happening at least 3 times a week now.


There are a few possibilities:First of all, don't use the factory alarm. If the problem disappears, then the alarm is causing the horn to activate. If that doesn't help, then verify the horn switch itself. Probably best to hav ... 2003 Hyundai Tiburon

The horn on my 2003 S-10 has stopped working. When I turned left or right the horn would blow without me touching the horn. Then one day, as I was turning left the horn started blowing and then stopped working completely. I did find someone had put a 30 amp fuse in the fuse box next to the horn relay (underneath the hood) so I changed the fuse back a 15 amp which the owners manual states use a 15 amp. I had the horn relay checked and it is fine. Any suggestions ? Thanks in advance


This sounds like it could be damaged wiring in the steering column. Would suggest a qualified repai shop, especially if the vehicle is equipped with an airbag. ... 2003 Chevrolet S-10
