Thread starter layoutshooter Start date Feb 28, I have a M2 business class. The book calls for series headlight bulbs.

I took an old one out and it had on it. I bought a set of lights that said they fit all aplications, they do not fit. My old ones are straight at the conector and the new ones have a 90 degree angle. I looked at a truck stop thinking maybe Wally World only sells car stuff and somehow the truck ones were different. Not so. I can only find the ones with the angle.

I was able to get the one replaced that was out, drivers side, but there is no way to get the other one in without cutting the light housing. Does anyone know what is going on with the series? Am I missing something? Robsdad Seasoned Expediter. I replace both low beams last week. I used halogen lights. They are a bit of a trick to install but work great. Install the bulb unit first and then install the plug in. Little tough to get it in but I could not find the and a Georgia DOT inspection going on 5 mile down the road so I had to improvise and you know whats next.

They waived me on through. Got new low beams anyway. Had one out in the morning walk around.The headlights on a freightliner truck can typically be adjusted using a vertical adjustment screw. The lateral position of the headlights is typically fixed.

Whenever you replace the headlights on a freightliner, adjust the headlight beam so that your headlights shine far enough down the road that you can see 20 feet in front of you. Unfortunately, because freightliner trucks sit so high off the ground, the headlights will naturally be aimed quite high, which might impair the vision of oncoming traffic, but there is not much you can do about that.

Park your freightliner truck facing a wall.

Make sure that the headlights are positioned 25 feet away from the wall. Look on the backside of the headlight housing.

Typically, there is a black or white plastic adjustment screw. Turn the adjustment screw with either a Torx head screwdriver or a cross-point screwdriver the exact type of screwdriver you need will vary according to what kind of freightliner it is. Turn the adjustment screw until the headlight beam shines toward the bottom of the wall. The headlight beam should touch the bottom of the wall where the wall meets the ground from 25 feet away.

A wiring diagram is a streamlined standard photographic representation of an electrical circuit. It reveals the parts of the circuit as simplified shapes, and the power as well as signal links between the gadgets. A wiring diagram generally provides info about the family member position and also setup of devices as well as terminals on the tools, to help in building or servicing the gadget.

A photographic layout would show much more information of the physical appearance, whereas a wiring diagram makes use of a more symbolic notation to stress affiliations over physical appearance. A wiring diagram is usually utilized to fix issues and also to earn sure that the links have been made which every little thing exists.

Click on the image to enlarge, and then save it to your computer by right clicking on the image. An initial check out a circuit layout may be complicated, however if you can check out a subway map, you could read schematics. The objective coincides: getting from factor A to direct B. Literally, a circuit is the course that enables power to circulation. If you understand just what to try to find, it ll ended up being 2nd nature.

While initially you ll just read them, at some point you will begin creating your very own. This guide will show you a few of the usual icons that you make sure to see in your future electrical design occupation. Voltage: Measured in volts Vvoltage is the pressure or pressure of electrical power.

This is normally supplied by a battery such as a 9V battery or mains electrical energy, the outlets in your residence run at V. Outlets in various other countries operate at a different voltage, which is why you require a converter when traveling. Existing: Current is the circulation of electrical energy, or more particularly, the circulation of electrons.

It is measured in Amperes Ampsas well as could just stream when a voltage supply is attached. Resistance: Determined in Ohms R or Oresistance specifies how conveniently electrons could flow through a material. Products such as gold or copper, are called conductors, as they quickly allow circulation of motion reduced resistance.

Plastic, wood, as well as air are examples of insulators, hindering the motion of electrons high resistance. DC Straight Current. DC is a continuous flow of existing in one instructions. DC could move not just with conductors, however semi-conductors, insulators, and even a vacuum cleaner.

In Air Conditioning, the flow of current regularly rotates between two directions, frequently creating a sine wave. The frequency of Air Conditioning is determined in Hertz Hzand is normally 60 Hz for power in household as well as organisation objectives.

Finishing an electrical design degree as well as then getting a job in the area suggests you will see a lot a whole lot a great deal of these schematics. It s essential to recognize exactly what is going on with these. Whenever you determine your particular area of electric design, you may see a lot more complex layouts and symbols.

You ll find out likewise that various nations utilize different icons. Of the two icons for resistors above, the first one is made use of in the U.Log in or Sign up.

Find Trucking Jobs. Apr 9, 1. Have no power to the right headlamp, the hazards only flash on the instrument cluster not on the front or rear.

Low air beep constantly going off. Basically the opposite of a 'No J' issue.

I have checked the fuse box under the hood, and also all the fuses in the aux distro box on the frame cross member.

Apr 9, 2. Check the grounds. I had major electrical issues in a Freightliner Columbia that were all due to poor ground connections.

Everything on the Columbia grounds through the starter. Wouldn't surprise me if the little trucks are the same way.

2006 Freightliner M2 - No Right Headlamp / Frt Ambers on fenders or Hazard lights

Apr 9, 3. Gonna move this to the garage. Apr 9, 4. Thanks for the quick reply.Welcome to world's most trustworthy automotive forum. Thread Rating: 2 Vote s - 1 Average 1 2 3 4 5. Reputation: Hi guys. I have a stomper here for all the freightliner guys. The truck starts and runs great. Although when I try to connect to any diagnostic software it will not connect. BUT when I connect to jpro. This truck has a allison transmission and cummins engine shouldn't it should all modules and is this the reason I can't get a connection with insite??

How to shift a 10 speed tractor trailer

I have replaced all fuses, unplugged each ECU to check for change. What is "adblue"? Thanks for ur response. Often the secondary datalink connectors cause issues with datalinks and adapters. Sounds like your J datalink is dead. Voltages should be about 2. If you read 0VDC or one leg is down, the datalink is dead - shorted wiring. Start unplugging components until it comes alive.

The Cummins engine has a triangular 3-pin Deutsch connector about a foot away from the ECM, normally tied to the harness on the front left of the engine. If the engine runs, the scan tool will commincate on this datalink provided the harness is not damaged. If you have the the three pin adapter to connect you can hook up there. J is on the 3-pin so you could make an adapter too. Thanks for ur response It sounds to me like a damaged CAN wire, some ecu's are fault tolerant and are able to work with bad communication wires.

I've seen some Cummins engined vehicles where the Adblue system SCR selective catalyst reduction in Europe we call it adblue leaked into its own wiring and caused problems. Thanks guys.

Thread starter truckblue Start date Nov 1, My M2 Business Class has a couple of electrical quirks. One is when I turn on my turn signal, my wipers come on and take a couple swipes then turn off.

The other is my headlight randomly goes off, then comes back on, usually after a few seconds. I thought they might be common problems for this model Wouldn't happen to have a wiring diagram laying around would you? I did some searching on the net and found this to start with.

Last edited: Nov 1, This is a multiplexed truck, I would get it into a shop that has the right tools to talk to the different modules. It maybe the one in the dash but that is a guess. Fleet Owner. Another brilliant offering from Freightliner.

You have a multi-function turn signal switch. The contacts have worn and it likely needs replaced. You can take the assembly apart and apply dielectric grease at the contacts, but that is a temporary fix. Very common problem on Freightliner and Sterlings from 05 and up.
