Primary wiring diagrams with a series parallel solinoid? Thanks Jim:. Posted Monday, December 26, PM. Posted Tuesday, December 27, AM. ATHS Member. Print out the two pages and tape them together for the full schematic. The Mack Museum will provide records for your serial number. You may get an email copy of records within hours but hard copies require a wait because of a backlog of requests. You should send them a donation for the great service they provide.

Charlie Hatfield.What is involved in converting a b model to negative ground? I know I have to reverse the leads on the heater fan and probably the ammeter gauge and fuel gauge.
Any other things to watch for or change? I am considering using a 8 circuit universal harness from EZ wiring or one of the other companies. The problems we face today exist because the people who work for a living are outnumbered by the people who vote for a living. I'll play the devil's advocate. What do you gain by going to a negative ground? If you want to use a modern electronic device like a cell charger or GPS it's much easier to make a negative ground auxiliary power box.
I made mine out of wood to keep it isolated. You can also run most electronics "backwards" by hooking the power side to the chassis and placing the ground to the truck's "power" side as long as you isolate the device from the truck's chassis. Converting means changing gauges, possibly the starter motor, as well as moving other wires around. I just don't see the great gain for the work involved. Money, sex, and fire; everybody thinks everyone else is getting more than they are!
My main thought for the conversion is to be able to use an aftermarket, universal wiring harness. Call me cheap but I gotta save where I can. I think you covered everything. Most starters will turn the correct direction neg. Just re polarize your generator. No need to replace amp meter, you just swap the wires from side to side, other wise it will read discharge when it is charging.
The wiring does not care if it is pos or neg ground the load through it is the same. You are only changing the path to ground not the volts or amperes.
Even somebody with a vintage car going from 6 to 12 volt the wiring is not an issue. Made mainly for the British resto vehicles and available through Foreign auto parts. Thanks everyone for the info and advice.
I'm sure I'm making it harder in my mind than it actually is. I've re-wired a few projects with the universal harnesses and had no problems. The positive ground issue kinda threw me off a bit. I got the gauges and matching sending unit from Summit Racing.
They were SW which fit the holes and looks of the originals. I think I saw somewhere on here that SW made the gauges for Mack. Good Luck. I converted my B61 over and I don't remember if I ever did anything with the heater and defroster motors.
Now that you mention it I didn't change anything with the heater motor. It works fine so far. Wiring a vintage truck is pretty simple to do one wire at a time if you choose to do so. You basically have two options; remove the existing harness and make a new one to match it or pull each wire individually using a container to run the wires through such as asphaltic wire loom.All of the B diesels would have been 12 volt, sometimes 2 6volt batts were wired in series to give 12V this setup would have had 4 batteries.
Good advice there from Truxnut. Most diesel B's I know of were 12 volt positive ground running and 24 volt starting. You do have a series paralell switch under the buddy seat don't you? Your best bet is to pickup an older Motor's Repair Manual for trucks from the sixties or early seventies which'll give you some good wiring schematics on the wiring spagetti your truck probably has. Watch Ebay where they go cheap enough.
Make sure that if you use 4 six volt batteries that they're all good because one or two bad ones can screw up the circuit breakers in your series paralell switch.
IVECO Truck Service Manuals PDF & Wiring Diagrams
What that switch does is normally each pair of six volt batteries in series putting out 12 volts, are connected paralell in the series paralell switch to put out 12 volts and run the electrical system and are charged that way.
When you push the starter button, the solenoid engages the series paralell switch to connect each 12 volt pair in series instead of paralell to put out 24 volts to the starter. That's that heavy clunk you hear under the seat when you start your truck if it's working right. Good luck, Bob. It does have six wheels but that includes the front axel. I have always thought the S stood for "service". You can post now and register later.

Posted April 29, Ain't a Mack?The Italian concern, which produces cars of industrial importance - trucks of different carrying capacity, special equipment, buses, fire trucks, dump trucks, tractors, engines. The company is also trying its hand at creating SUVs. The name stands for Industrial VEhicles Corporation. The uniqueness of this education is that all the companies have continued their previous activities, having replaced, in fact, only management and brand.
The union was beneficial - in the first year, 95 thousand cars of various purposes were produced. However, the quantity did not mean quality - as it turned out, it is difficult if the produced models differ so much from each other.
They urgently needed to be unified. Many of the produced cars were withdrawn from production, others replaced them. The first truck, about which it was possible to say that it was produced namely IVECO became, appeared ina heavy van Dailywhich was sold in the same way as Fiat Daily.
To date, several generations of the Daily have been released.Discussion in ' Trucks [ Eighteen Wheelers ] ' started by joecitizenDec 28, Each company we work with has specific experience requirements for their drivers.

There is no charge for this service, but standard message and data rates may apply. Something does not look right to me. Are you sure the batteries are in the right direction? Looks like the pos from the truck is hooked up to the ground if I am looking at that right. Also I am not sure about those 3 wires. To me they look like they have been hot.
It looks like a lot of brown on them. The more I look at that I am not sure. The closest battery looks like a negative symbol - on the right side.
Maybe it is just a smudge tho and not a negative sign. I finally had enough and added another ground from the battery to the block and the problem was solved. Dec 30, My guess is the arcing you saw was when you put that one positive wire on the negative terminal. When you hit the starter, it tried to ground the entire system to the wire that is near the negative but not connected.
Thus making me wonder what condition the rest of the electronics are in. Your attempt to save you money may have just cost you.
Please take a photo of the other end of batteries. Last edited: Dec 30, Free Wiring Diagram. Variety of mack truck wiring diagram free download. A wiring diagram is a streamlined traditional photographic depiction of an electric circuit. It shows the components of the circuit as streamlined shapes, and the power as well as signal connections between the gadgets.
A wiring diagram normally gives details about the family member placement and also plan of gadgets as well as terminals on the devices, in order to help in structure or servicing the tool. A pictorial layout would reveal extra detail of the physical appearance, whereas a wiring diagram utilizes an extra symbolic symbols to stress interconnections over physical look.
A wiring diagram is typically made use of to troubleshoot problems and also making sure that the links have actually been made which every little thing is present.

An initial appearance at a circuit representation might be complex, yet if you can read a metro map, you can read schematics. The purpose is the same: getting from point A to aim B. Literally, a circuit is the path that enables electrical energy to flow.
Voltage: Measured in volts Vvoltage is the stress or pressure of electrical energy. This is usually provided by a battery such as a 9V battery or keys electricity, the electrical outlets in your home operate at V. Electrical outlets in various other countries operate at a different voltage, which is why you require a converter when taking a trip.
Present: Current is the circulation of electrical power, or even more particularly, the circulation of electrons.
Proper Battery Wiring Configuration
It is determined in Amperes Ampsand could only move when a voltage supply is attached. Resistance: Measured in Ohms R or Oresistance defines how conveniently electrons can flow with a product. Materials such as gold or copper, are called conductors, as they conveniently permit circulation of movement reduced resistance. Plastic, timber, and air are examples of insulators, hindering the movement of electrons high resistance.
DC Direct Current. DC is a continual flow of current in one instructions. DC could stream not simply with conductors, yet semi-conductors, insulators, as well as also a vacuum cleaner.
Air Conditioner Rotating Existing. In Air Conditioner, the flow of current regularly rotates between two instructions, commonly creating a sine wave. The frequency of Air Conditioning is measured in Hertz Hzand is commonly 60 Hz for electrical power in property and also company functions. Currently s the enjoyable stuff. Completing an electrical engineering level and afterwards getting a work in the field suggests you will see a whole lot a whole lot a great deal of these schematics.
It s important to recognize exactly just what is happening with these. While they could and also will get extremely complex, these are just a few of the usual graphics to obtain your footing on. Beginning to make sense? These are the essentials and also may even appear evident or instinctive to you, such as the wires as well as if they are linked. Whenever you identify your details area of electrical design, you could see a lot more intricate representations as well as signs.
You ll discover also that various nations make use of different signs. Of the two signs for resistors above, the very first one is made use of in the U. You will likewise learn more about the different symbols made use of for buttons, other power products, inductors, meters, lights, LEDs, transistors, antennas, as well as a lot more.By John R.
