The reason for this is LEDs don't draw as much power as regular incandescent lights do. By putting the LEDs into the vehicle, you are making the vehicle believe the lights are out because of the lower draw. The indicators blink faster to indicate to you, the driver, there is a bulb out which needs to be changed. One way to fix this is to put a resistor in ...

The power of your compressor is given by P = V x I = 12 x 30 = 360 W. This sounds about right. It sounds as though your compressor is badly made and that the pressure switch is not adequate for the job. You could try to modify like this. Figure 1. Relay control of compressor motor. Rewire the unit as shown. Use a 12 V relay rated for > 40 A. Your ...

You can easily test a relay in a few simple steps. The required materials are as follows Digital Multimeter (with continuity setting) 12V power supply (Optional) Aligator clips for hands-free testing DO NOT USE YOUR BATTERY DIRECTLY FOR THE 12V SUPPLY, if you have nothing on hand and want to be safe please use a fused line from a harness or through the ...

Not sure what it "should" be pulling, but anywhere near a whole amp is way too much and will drain the battery in no time. Are you sure you tested right? Often the pull when you first connect the battery can be a lot higher than the steady pull since you might be charging some capacitors, etc. If it stays that high you definitely have a problem, possibly a ...

Your question raises more issues than you probably thought. With respect to the issue of a relay, then assuming your bike has a 12 volt, negative ground, electrical system, all you need is a generic automotive relay, which looks like this (sometimes called a Bosch relay, regardless of whether it is actually a Bosch unit). Here is an article, which looks ...

Just FYI, I had a 1999 Pontiac Grand Prix GTP (same basic engine and transmission I think, GM 3800 Series II engine) that the fuel pump relay went bad on. When you turned the key, you could here the pump power on and pressurize. The car would start and idle, but as soon as you put it in drive or pressed the gas, the engine would die. I've been told that ...

Very possible. Letting a fuel pump run dry can quickly burn out the motor in the pump. The presence of fluid keeps the impeller from rotating as quickly and the gasoline also cools the pump as it operates. Without gas flowing through it can quickly overheat. That being said however you may just have air in the lines. I am not sure whether your vehicle has a ...

Why are you assuming that the fuse is only for the AC fan? It seems really strange that only one of the fans would have a fuse on its circuit. Replace the fuse, since you'll have to do it anyway - if the fan still doesn't come on, then start looking at other possible causes.

It can be done with a power source and a standard VOM. Apply appropriate power source to appropriate pins while listening for click and looking for the desired effect (could be presence vs. absence of voltage or continuity/lack of) on the VOM which would be attached to the appropriate pins. You'll want a repair manual to find out what to replace ...

Relay is here: That's in the driver's footwell. I believe it's above the fuse box, around the hood open latch. There's a plastic cover over the relays you'll have to pull off. There's one for the relays and one for the fuse box. It should just pull out and the new one can be popped right in. You'll have to pull hard.

Your single bulb has two filaments, one for the low beam and one for the high beam. If you look at the back of the headlight bulb, there's three prongs. One is for the low beam, one is for the hi beam, and the last is the shared ground. The low beam and hi beam need to be turned on and off independently, so you need two relays. (image source ...

Can be a lot of fun to track down electrical parasitic culprits? Had one battery draw that caused soft brake light bulb contacts to re-form into concave shape from convex shape touching brass wiring contacts. Caused from too much bulb heat? Never-ever saw brake lights on while parked with foot off brake either. Weird! Did track down to faulty brake light ...

Here is more info than you would like http://www.aeroelectric.com/articles/strtctr.pdf The short of it is that it takes 8-10 amps to hold the solenoid in place while starting but the draw can spike to 30 amps while it is engaging. This is assuming that the ignition switch is carrying the current for the solenoid, new cars with push button starts and some ...

Use an electronic flasher. I have no idea if Tung Sol is still in business, but they made a very nice electronic flasher that simply replaced the old bi-metal unit. True plug-and-play operation: remove the old flasher, plug in the new. Note that even though this was classified as an electronic flasher, the only electronics inside was a really cool relay ...

It sounds as though it is one or two things going on here. First of all, did you check the serpentine belt which drives the alternator? Is it still on there and looking ready to do its thing? If that is still there, it could very well be the alternator itself. I've had alternators which have completely froze up. From your description, this could very well ...

The headlight control unit is in the sealed portion of the box. It is a CAN network controller and not just a relay. If it has failed the whole box is to be replaced.

How 11-pin flasher relays work internally. See this wiring diagram: It is for the BOSCH 0 335 210 250 flasher relay (same as yours, only for 12V). The diagram shows the internal components of the device logically (physically speaking, there are some more inside). How to connect 11-pin flasher relays. According to the above diagram, this is how you ...

0.10 amps will kill your battery quick like, you should get it down as close to 0.00 amps as possible. My experience was that to keep the radio stations, etc. it takes about 0.01 amp on the meter. So yeah, you got something going on... In my case, it was the key lock light staying on and the door lights (or rather door light relays) staying on.

I'll try to dig out some E60, diesel-specific information if I have time, but consider the following as possible culprits: clogged fuel filter faulty fuel pump relay weak fuel pump

The relay has two independent NO contacts. Doesn't matter which is used. Also, the specific wiring locations of the horn and switch don't matter either, but this is the general idea.

I'm not sure there is anything physically wrong with your clutch or belt. The clutch is designed to be turned on and off as needed. You can test the clutch by locating the relay located in the engine side fuse panel, then jump the power to the clutch pin. You have to pull the relay to do this. If you can manually engage the clutch by doing this, you can ...

you might need to check the relays in the fuse box, without forgetting the fuel regulator.

The ECU can measure 3 primary sensors in the cooling system. Engine thermostat for the engine temperature, the engine coolant temperature tracks this. You can also have a temperature sensor for water temperature into the radiator and a temperature sensor for water temperature out of the radiator. The radiator sensors decide the plausibility of the radiator ...

I have 01 Chevy Tahoe it will start up for about a second, idle up then shutters an then shutt down when given gas. I replace the mass air flow sensor thinking that was the problem but It was not. Then I replace the fuel pump relay did not work again. so I was thinking to sale it by then. But last an not lease the fuel pump fixed the problem.

If you want to build the relay setup yourself instead of using a commercially produced motorcycle headlight relay kit, you'll need two automotive relays, commonly called "Bosch relays". They should have a rating of at least 10A, which they nearly all do (generally you find them at least 20A). You need one relay for the low-beam, and one relay for the ...

Mine was pulling 3amps, 3.6 amps to be exact. What had happened was my Volt Regulator, that regulates how many volts run through your car, went bad. I had boosted and jump started my battery over 30 times, I knew it wasn't the alternator because in the 90s they didn't have the regulator in the alternator and if it was the Alternator the car would run dead on ...

You want to perform a Parasitic Battery Drain check, as shown here. Once you find the culprit, isolate and correct.

Could you not just connect both the starter solenoid and the spark control wire to the single output of a standard automotive relay?

I had to do this recently, like Brian said you'll need a power source and a multimeter. Most relays have a wiring diagram printed on them and most automotive relays are 4 pronged. Two prongs will be your positive and negative power and the other two will be the bridge that is made. What I did, and this was a very very cheap method and suggest for possible ...

You should be able to pull them out with your hands, if it's the kind I am thinking of (in the fuse box under the hood) there is no latch or anything else holding them in.
