You need a test lamp, very basic old school type And a analog multi meter, nothing fancy, not digital If your not experienced a digital meter can lead you up the garden path very quickly This way when Geoff or someone else asks a question you can give a positive correct answer on exactly what you are looking at Also a couple of leads with alligator clips And if the budget can stretch a few more dollars, a set that plugs into your meter Now remember the golden rule, "always test the tester on a known supply" So test the test lamp on the battery, then test it on the ground your going to clip alligator clip to from the test lamp Once ground is established amd proven then test what ever it is with the probe Once found a reading that's a bit sus, recheck the tester encase the ground or tester has changed You don't need flash test gear and 99% of your faults will be found with a test lamp, thats all most workshops had back when this fire truck was built So keep it really simple Geoffs your man here, he is much much better with words than I am Paul

I have just the right hand side of this hanging on the office wall to explain to the apprentice about things like this Paul

I probably came across a bit harsh That wasn't my intention I'm trying to just get you to not just start changing things and fiddling and making it worse I have worked on a lot of plate rectifiers over the years, worked on a lot of generators and alternators, mainly on the electrical side of things It is how I got my start in the world as a young man, so I do have some idea what I'm talking about Goeff is very switched on, listen to what he is saying I tend to stay out of giving advice on electrical things like this as everyone else has plenty to say and people that don't understand things can get very confused Your ground (which by the way, is what I think is wrong) wont be a wired connection as such, at least I doubt it will be, it will most likely be the connection that the regulator or what ever is faulty is attached to So I was taught as a apprentice, and still use these princables Always prove the fault before changing anything Prove the bad connection before undoing things and cleaning Prove the faulty rectifier before tampering with it Prove the faulty alternator before sending it off to be reconditioned By doing things this way you teach yourself actually gind the fault If don't prove things your only guessing and potentially making the problem worse and waisting time and money Anyway, good luck and I'll stay out of this unless asked My only advise is to prove the fault before changing or adjusting anything Paul

Test the rectifier before changing it Simple to test If it was mine and it's not I would stop just guessing and start testing things To me there's a lot of guess work going on The alternator is working, we know this as it's over charging so leave it be The rectifier is working, your getting DC from AC so leave it The regulator isn't working It needs a reference to know what voltage to regulate at Do you have voltage at the regulator And yes replacing the alternator is the easiest way to solve this with a modern type But this should be easy to fix Paul

Does this have a socket to plug power in to keep it charged when parked in a fire station? I don't know about fire trucks but have been sent to repair power supplies etc at ambulance stations in Australia and they have a lead to plug the ambulance in This must be unplugged before the ambulance starts Am wondering if this rectifier is similar part of the charging to the ambulances I have worked on and nothing to do with normal charging off the fire trucks generator Not knowing my ass from my elbow about fire trucks I can't really advise I can only imagine they are built to be able to idle for hours on end and run on full power the same No matter now, all we for sure is it's charging but not regulating As far as polarizing goes, I'm pretty sure thats done make it either positive ground or negative ground Paul

I must be more gung hoe than most The head would of been yanked of the motor weeks ago if it was mine Not to mind, to me it's pulling a bandaid off, you can stuff around but I reckon I'm best to see the bad or good news right away Yep, yank the head, roll the push rods on a sheet of glass Check the cam Work put whats what and put a plan together Paul

Over drive and or bigger tyres Paul

Done and dusted Come on you lot get behing the Bull dog breed, help these jokers have a win Good luck to both you all

Well there's some hairy chested Mack action here Some how I just can't imagine Volvo power been this awesome Paul

Sorry Joey, I haven't even seen this but rather got a phone call last night asking the question I asked here I can ask for more information and see whats forth comming I will update as I learn more Paul

Okay, I'll report back then, I wonder if I sent Barry a message if he can shed some light No good asking a Mack dealer in Australia, it would be like asking a Mack dealer in the States about a Australian truck Thanks for your help Paul

That's amazing, yet not surprising I remember reading or hearing somewhere many years ago If motor bikes were invented today they would be most likely made illegal as the are so dangerous Not at all suggesting that's my opinion, but there definitely is not a lot of crumple zone on.a motor bike I remember going to see the Crusty Demons years ago, while the stunts were spectacular to watch and left my jaw firmly planted on the ground watching them I couldn't help but wonder how they do survive, I fall of a truck tray or trip over something on the ground and I can be hobbeling about for a week as a result Yet these blokes are spinning about in the air and not always landing as planned, surely some of their landings have to really hurt, very good to watch though Paul

Scania motors that I know of have separate heads for each cylinder Apart from that I have no idea Paul

So can info be read from the model number etc Such as motor specs, drive line specs or any factory specs at all? Paul

Had a phone call with a strange request A new in the U.S of A Mack now living in this wide brown land Off this information can anyone provide any details Apparently it's a 2005 6x6, that's all I know Oh and these numbers are no good in Australia so do they mean anything to Americans ?? Paul

Rowdy you seem to know a lot about these Tesla's I remember way back in last century when in high school, when a young bloke had the hots for bird and his mates twigged he would deny it vigorously, in fact he would not have anything nice at all to say about this bird he was in love with Makes me wonder about people that can Tesla's Don't worry I'm only stirring lol, Im not overly fond of things that drive themselves either Paul

Sorry lads, motor bikes only have to go fast enough to out run a cow As for riding on a road, it has never interested me at all, which is just as well from what I read here Rowdy Rebel sounds like you need a Tesla, cheap to drive and no transmission woes or heads to bugger up I often come across woman talking about horse riding and what they reckon is law on motor vehicle edicate My thoughts are probably just as relevant for riding a horse on a road as for riding a motorcycle on a road, "the law isnt really important if your dead or worse still" Happy days everyone, stay safe out there Paul

Gudday and welcome Paul

Im interested to see this tilt tray working This is a whole different style than is used in Australia Looking really good Paul

This was sent to me today https://www.facebook.com/marketplace/item/1474590240004274/?mibextid=dXMIcH Felt it might as well go here as well Paul

Your younger in this picture than I imagined Gotta love the C model Paul

The motly crew Looks like a beaut day Paul

I wonder if the green is the gel coat they seal fiberglass with Paul
