Vorad
« on: March 06, 2026, 01:49:54 AM »
Hello. I have a 2008 Beaver Marquis. I was hoping someone would know the location of the Eaton Vorad EVT 300 CPU. I believe it has failed and would also like to knwo if anyone has a suggestion on replacement or repair. Thank you

On my 07’ Marquis, it is located inside the left side switch cluster just to the left of the pilot seat. As of now, there are none available. Rick Youngblood was the go to, but last I heard, all of his stock is gone. I have replaced mine twice, so knock on wood, it keeps working. You can get the Cruise Control to work if you cycle the on/off switch 3 times, but the Collision Avoidance System will not work. Not the news you wanted to hear, but at least the CC will still operate. Good luck!

Hi Frank. Thanks for the prompt reply. I did send Rick an email earlier hoping he could help. Haven't heard anything yet. I thought I looked thoroughly for the cpu where it should be but I didn't see it. I'll look again tomorrow morning. Beaver coach sales, Mike thought it was located elsewhere but couldn't remember where.  I see numerous units on ebay but assume they would need specific re-programming. That might kill the project. Did you need to reprogram your 2 units? Any other thoughts would be appreciated. Take care. Mike

The CPU is back behind the cluster of wires, mounted to the wall, making it difficult to see. Keep looking, it is more than likely there. Removing the pilot seat makes the job a lot easier. As far as programming, Rick told me that the two new ones I received were updated with the newest updates. The ones on E-bay, from what I was told, are programmed for trucks and would be difficult to adapt to our motorhomes. Might ask Rick if that is something that might be possible. Good luck!

Boy you were not kidding about the CPU being behind a bunch of wires! I did locate and remove. My unit has a number 80628-164 and the label says replace with the same number. I see several used units on Ebay with the same core number (80628) but different suffix numbers. like -161, etc. Do you have any idea what the difference is? I assume that suffix number matches up with what is was originally programmed for. Any thoughts would be appreciated. Unfortunately, Rick Youngblood has not responded to my email as yet. I'm sure he could clear this up in short order. Cheers.

I really don’t have any idea concerning the different numbers. Hopefully Rick will get back with you. Over on the Monacoers forum this topic was brought up and presented to a couple of the forum gurus about trying to figure out how to repair these CPU’s. As of now, no solutions have been presented. You might consider joining this forum, lots of really good info concerning Monaco motorhomes! If your coach has the Kongsberg CCM, one of these guys has recently figured out how to repair this system, saving several motorhomes from the scrap yard. He has developed some safeguards to protect the CCM from failure. Well worth your time! Good luck!
