Hey guys, this is my first quad and I have had it for about a year. I have narrowed down this issue somewhat but would like some advice before continuing to work on this. My quad is a 2005 scrambler 500 4x4. The problem is when going through water / mud or even just hosing it off, if water gets under the "hood" and onto the electrical components, it will run horrible. It idles just fine but to much throttle and it acts as it is limited, just like in reverse without the override button pushed. This is how it will run regardless of what gear you are in, 4x4 on or off, with or without override button pushed. Once everything dries out, everything runs great again.
What I have figured out so far is this.... I unplugged the harness going to the little module that I believe does all this limiting and when doing that, no more problem at all. However, with that came no 4x4 so obviously that's an issue. I do like the idea of getting rid of the override button completely for when stuck in mud and trying to go in reverse. So my question at this point is, is there a single OUTPUT wire that send a signal out to kill the spark for the engine that I can just disconnect? Or something along those lines..... or is this more complicated then that? I am good with electrics. I have meters, test lights etc. But I have no wiring diagrams and don't know what any of these modules actually do yet. This is the first time I have had to work on this since owning it. Figured I would get some input from someone else and maybe save a lot of time of just trying to figure it out. Thanks
