Rewire the Entire Bus

[luvrbus]

I expect the Multiplex Monster is here to stay and from what I've just read here I'm feeling a little less sheepish for having spent $1,500 on a dealer level diagnostic system for my insanely multiplexed Isuzu chassis and drive.  Jack

Yep it is here to stay he needs to shop and buy the software for a lap top it pops up on Ebay at good prices from time to time.I know a guy you attempted that on E4500 and ended up selling it for scrap after 3 years and many of $$$$ it is a good system but hard for a layman to understand for awhile till they figure out the working principals

Glenn,

I'd think hard and long about rewiring your bus. And then I'd think again and wait, then think again. Once you rewire it, you no longer have a D4500 on your hands so you'll be on your own for any electrical help. Granted, much of the multiplex system is dedicated to passenger comfort/safety devices that are of little value to a bus conversion, but many other devices (head lights, blinkers, marker lights, etc.) rely on it. Your bus was designed from the factory to support that multiplexed system. A major benefit of multiplexed systems is the reduction in wire.

I certainly do understand the issues with taking on such an endeavor. I'm really only on a rant here, as this system requires a certain amount of education and equipment to learn or repair. At this point, I have no problem paying someone $2-3 g's or whatever to fix the thing and get some education in the meantime. I only want the thing to run. I have very little money into it so far; I'm having a great time working on the conversion/demo stuff, but at some point I'll need to start purchasing materials and getting on with it. If I can't find someone to get it running, it takes the ambition out of the process. Hopefully the mechanic I'm working with (sort of) will get back to me with some ideas on how to fix it. I can't say I have complete confidence in him, as he had the deer in the headlights look after looking at it. Even with that, I will be getting some parts from the company he works for, such as a new hinge for the sedan door I plan to install. They are willing to trade some parts that I plan to remove for the hinge that I need; stuff like that. We'll see how all that goes. Thanks.
