28410 has a thicker disk, .472” compared to .437” on the 27406. .035” doesn’t seem like much but when you factor in torque and flex on a steer axle it can mean the difference between turning and have a wheel flex to the braking point.

part number 2841 has no hand holes, according to this.  http://www.wheelsnowinc.com/catalog/viewItem.php?id=228.  Might be for front wheels of dump trucks or something.

Edit:  The accuride product lookup says it has two holes.  http://www.accuridewheelendsolutions.com/products/accuride-wheels-product-search/

Here's my relay 11a configuration today. Note that it matches the DDECII wiring diagram I got from Setra.



So what the heck are wires 543 and 531. What does the DDEC _expect_ them to be. In reading some other posts on the interweb it looks like you need 543 to be ground for cruise to work. Which it is, since 538 coming into the switched side of 11a goes through to 543 in the non-energized position. 538 is the switched ground from the cruise control on/off switch.

But what throws me is 531. Someone said that also needs to be ground for fast idle to work via cruise control. I have a separate high idle switch, so that's not my issue but it makes me think 531 is supposed to go to ground in the cruise-enabled situation. But my 531 never makes it to ground today and my cruise turns on.  Undecided Because relay 11a was never energizing before, 543 was always grounded when cruise was on and 531 never was.

Looking at the diagrams again it seems the DDEC3 diagrams tell me that 543 should always be grounded in "on" operation. If I had a B500 trans, when the retarder was enabled 543 would no longer be grounded and would instead receive +5V. This would disable cruise.

It also seems that 531 should always be grounded in "on" operation. By the DDEC3 diagram, hitting the brake and energizing relay 11a should break the ground for 531 and disable cruise this way as well. That's all well and good except for the fact that this "break the ground for 531" scenario which should prevent cruise from working is precisely the scenario that's happening right now in my bus and cruise is enabled/working.

I don't understand how 531 and 543 relate to one another.  Huh

Scott where did you get the wireless toad lights? sounds like a solution to a problem I am experiencing on a non-bus vehicle!

Hey folks. I'm chin deep in getting my cruise control switches working. I will fix this before departing in a few weeks. I've spent far too much time chasing wires already, but I'm now stuck on the retarder.

I have a few diagrams for DDEC2 (which is what my bus had original) and DDECIII (which is what my bus has now) but *nothing* I have mentions the transmission I have. Everything references a B500 and I have an HT-748.

Anyway, so I was able to figure out the brake light wiring and how it makes its way through the series of relays to finally trip the relay that disables cruise. Had to swap two relays but now that correctly clicks over when the brakes are applied. Where I'm caught up now is in the retarder wiring, as this too should disable cruise.

Let's start with the DDEC3 diagram.


The retarder and the brake light should energize the coil on relay 11a (that's my cruise disable relay). In the non-engergized position it allows wire 538 from the cruise switches to continue to wire 531 at the DDEC. That wire is "Service brake released". There's also a retarder switch that seems to be powered by +5V, and some mystery wire 171. This is supposed to make its way to wire 543 at the DDEC which is labeled "Cruise control off" on my diagram.

I have absolutely NO idea where this retarder switch exists, or if it even exists on an HT748 not a WT-B500. I have no idea what (if anything?) I should be sending to wire 543 on the DDEC. I do see two pressure switches in the air lines leaving the retarder. One is hooked up to 24V power which continues on to the RET light on the dash. The other is hooked up to 12V power on one side, and lord knows what on the other. I can't figure out where these wires go.

Any thoughts out there from any of you?

We got Gary going. The ECM lost it's 5 volt power supply to the throttle position sensor. Gary checked every related circuit to make sure there was no opens or grounds where there didn't need to be. Then he tapped into the 5 volt sensor supply on the engine side and connected that 5 volts to his throttle and away he went. I think he's headed south but in no hurry.

Yes Gary you had 2 of the best.. Just missing BK, Don and a bacon thief.  Then it would have taken 2 weeks rather than 2 days.

Have a good rest of the trip, and keep rusty out of trouble. No Alaskan spring water.

pn # 27406 is a 7400 lb wheel (two hole) and # 28410 is a 8000 lb wheel. (two hole)

Does it matter which one a person buys for the steer axle on a model 05/10 Eagle.

Unless my numbers are wrong, why would they even build a different wheel that is 400lb different ?

Thanks  in advance Smiley
