CTIS is also 24v... A 100A alt @24v will meet 100A @ 12v thru a converter no problem. Watts are watts regardless of the source. 100A @12v = 1200W. 1200W@24V is only 50A... why you need so much 12v capacity? The total lighting load is about 25A and that is the lions share of it, so you would...

FYI: 27.5” fan and a 10.5” hub works out to be 3.52 sq/ft of blade area. Fan Clutch Engaged: 750 RPM = 2100 FPM Velocity measured X 3.52 SQ/FT = 7392 CFM. 2600 RPM = 7000 FPM measured X 3.52SQ/FT = 24,640 CFM. There are other ways to do this. Like with a electric controlled clutch used on...

Oooh now you gone and dun it... well you are Probably not driving it home. Crank no start, probably fuel system... Said they couldn't raise the cab Hand pump or hydraulics inop? .. Hmmm Looks as if someone started to work on a driveshaft and that's when they decided to send it to DRMO...

Why do you think they went to so much trouble to make these things easy to tow(front gladhands, towbar setup, front trailer light recept)...:)

In a floor drain? No not supposed to be there...

Call omni glass and paint in Oshkosh WI. I got one thru them last year, pretty reasonable...

Well these are the joys of electronic fuel injection... although the way cat went about it seems a little bit prone to failure(or planned obsolescence). Have run Toyota EFI vehicles and tweaked and modded a lot of them Since the mid 80’s and I have never seen a bad toyota ECM...

Being in germany, you might have trouble getting a used one and might be better off with a european cat rep. They can take your engine s/n and should be able to get the proper software in a new one to match the spec the engine was sold with...

Glad I could help. start a new thread on your no start, be sure to include the year and model truck...

Chucky has it right. I was refering to the Coil ratings Of individual relays, either 12 or 24. There are no dual rated ones that I am aware of. 12v and 24v relays are basically the same, they simply have different coils... In fact if you were really hard up for parts, you could probably...

I have done smaller ones with a large c clamp and sections of steel pipe big enough to fit over the bearing cups...

The 12/24 is the coil rating. If you take an ohm meter and measure the two coils they will have different resistances. basically the two different coils are wound differently to make the same amount of magnetic force From different voltages. So 12v coils with 24v applied Have way to much...

Not a gremlin, just that 12v relay coil started to fail after years With 24v applied To it. 4 pin relays have top, bottom left and right. The 5th pin is at the middle of the cross. if you pull K12 to the left of K15 you will see top, bottom left and right connectors On the panel and no...

My truck had a 12v relay there as well when I got it. I dont have an aux cooler, I noticed it because it was warm... K15 also has to be a 5 pin relay Or your cooler fans will never come on... under normal conditions when you turn on the main sw, K15 should energize. The fan solenoid air...

Yep, ears and hands first, but I always find more with the soap:)

that is probably a HEUI High pressure oil regulator valve Or pressure sender. It is a solenoid that controlls the high pressure Engine oil used to power the injectors hydraulically. HEUI 101: Engine oil is pumped at high pressure between about 500 and 3000 PSI To a gallery that feeds all the...

Well it doesnt sound like your lifting ram has failed, it sounds like your latch seal has, so your latch wont release and you cannot build pressure to the ram to lift the cab. Like was mentioned earlier in this thread, disconnect the hose from the cab latch and cap it. I forget where exactly...

Look at the placard to the left of the steering column. It should have a “D” stamped on it somewhere. I believe that was to indicate it has updated driveshafts. There are NO electronics on the engine:) it is a mechanical governed engine using Mechanical Unit Injectors(driven by camshaft)...

What engine was specified on the truck that you bought/bid on? the A1 was not fielded until July of 2000, so there is functionally no difference between a 95 and 98 truck... They both had the same 225 HP 3116 engine and 3070 Transmission. Late in 98 they switched to a WTEC III trans, but...

A1’s dont have a fuel solenoid, they are electronically controlled fuel injection...
