Solution Joey Mack Posted August 6 Solution Share Posted August 6 I used to take a seperate battery, and run a power wire to the EECU fuse, and clip a jumper Cable to ground in the truck, then crank it up. Most common repair was a bad starter, provided the batteries passed a load test Quote Link to comment https://www.bigmacktrucks.com/topic/74419-having-trouble-starting-a-2003-mack-ch/page/2/#findComment-556537 Share on other sites More sharing options...

Most common repair was a bad starter, provided the batteries passed a load test Interesting you say that as i have another truck with the e7 etech (which im keeping ) and same batteries started it no worries. So the starters like to die in this way, interesting. Got an old school load tester (one that uses a heat coil) and found it to be super reliable so will try out the batteries tomorrow. But would a starter get damaged from sitting for a few years? maybe the high pressure washing left water in it?

fjh Posted August 6 Share Posted August 6 9 hours ago, Gorilla said: Ok just got back from the truck and found that no signal at injectors so electrical, checked voltage on battery while cranking and about 8.5v SOOOO tomorrow gonna put different more powerful batteries in and lets see. Fkn sure i bled it right, to be sure to be sure today cracked a two injectors and got no bubbles (at the head). Thank you all for the input i am seriously greatfull........ seems i didnt factor in that trucks suck up voltage like stupid.... my bad. Will keep you updated. All good get volts up and she will likley sputter to a start ! Get solid fuel to All six she likley light up clean! Been my experience if you get at least two banging it will go!

Most common repair was a bad starter, provided the batteries passed a load test DUDE YOU ROCK!!! SERIOUSLY you ROCK!!!! hooked up another battery to the EECU fuse under the bonnet and came to life first turn (seems my bleeding was spot on). Interestingly if i disconnect that jumper while the engine is running the truck dies which i suspect means the relay feeding it is not working right. Where is the relay that feeds it? where is this Fuse 40? keep in mind im in australia so steering wheel is on the other side. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74419-having-trouble-starting-a-2003-mack-ch/page/2/#findComment-556597 Share on other sites More sharing options...

Thanks mate again for your help as it was invaluable. Experience cannot be undervalued. BTW, here are some pics of the girl, yes the headlights are custom setups made by me Have the moulds to make more but damn it takes a lot of time to get them right in fibreglass. Front pic is right after vinyl wrap of large section, Left pic is final vinyl wrap finished. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74419-having-trouble-starting-a-2003-mack-ch/page/2/#findComment-556681 Share on other sites More sharing options...

Whichever pays better and whichever gets you around your family more. You could always hire someone to drive the tipper.

I dont know what its like in the USA but in Australia the tipper drivers get constant abuse and they all put up with it (except me thus i quit the work). Gets real old real quick hearing constant abuse of other tipper drivers on the uhf, i never accepted it and one day the excavator operator went too far and i figured ill walk away before i get a criminal history. As for finding drivers here yeh nah, hard to get a local and the imports (cant name which ones as thats not socially acceptable in this "free" "democracy", yes we both have no freedom of speech) yeh well they cant drive and they lie...... every one of them has a gazillion years of experience and all the papers but for some strange reason they dont know how to operate the equipment. Ill sell the old girl cheap and be done with tipper work. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74419-having-trouble-starting-a-2003-mack-ch/page/2/#findComment-556702 Share on other sites More sharing options...

"think of the fly" in australia? are you kidding me, most so called "blokes" cant figure out how to change a tyre........ as an example of stupid my x boss demanded i drive a truck 40km to get a radiator hose repaired, i told him ill cook the engine but he demanded i do it and just stop every 5km at a petrol station to fill the water......... i did this and called him each time that it goes out as quick as i put it in but again he demanded......go to the "mechanic" and his jaw dropped that i drove it at all. Truck never went the same but hey we argued and he demanded. Sadly this is the mentality in this country, most are stupid.

Gorilla Posted August 8 Author Share Posted August 8 Dont get me started on workmanship of mechanics. Im a bit of a french car nut and know my way around the citroen hydroactive suspension system (the one most so called "mechanics" think is black magic and wont touch these cars). Anyways i was at a mechanics picking up some parts for my car as they also ran a wrecking yard and we got talking and they told me their "mechanics" had trouble with a hydroactive system.............met the owner of the car and he was a top bloke so i figured id help them sort it out............. not kidding when i say the following: 1. they used a impact gun on a thread that goes into aluminium in the suspension, screwed the thread and left it like that 2. they didnt want to remove all the bolts around the lower control arm to make it easy to remove and forced it out and back in 3. In the process of forcing it back in they bent a height sensor but left it like that because who cares 4. they couldnt figure out why the car was not lifting the rear and over lifting the front and burnt out the hydraulic pump 5. told them what they did and in front of the owner of the car, the owner of the mechanical workshop i told the so called "mechanic not to use the gun on aluminium suspension components and as soon as we turned around guess what the moron uses the gun and guess what he also screws the thread!!!! Lost my marbles and called him a moron in front of everyone, he had nothing........i walked off. Owner of the workshop begs me to help them as the owner of the car is losing his mind, told him ill do it ..........spent 1/2 a day fixing it to work, it worked but everything was not right as the morons did other work and i didnt trust them......... Long story short i told the owner of the car to go to someone who knows what their doing and the owner of the workshop to hire competent mechanics as he will kill someone......he told me he tried but none around!! WELCOME TO AUSTRALIA! Sure there are a few good mechanics BUT most yeh nah.

Popular Post Gorilla Posted August 14 Author Popular Post Share Posted August 14 Hey Everybody, Update:Truck Runs perfectly and all is resolved. In my years with cars and now trucks i have never ever every seen a fuse that works well until it is under load but this one did that and when tested showed it was good but when under load stopped working. Also some moron put a 15 amp fuse where clearly it says 25 amp....this is now resolved. Thank you all for the assistance, it did help 3 Quote Link to comment https://www.bigmacktrucks.com/topic/74419-having-trouble-starting-a-2003-mack-ch/page/2/#findComment-556993 Share on other sites More sharing options...
JoeH Posted August 14 Share Posted August 14 These trucks don't use fuses, they use circuit breakers. Overload them and they trip, then they reset themselves.
