Fed up with electrical issues

Ok so been riding all day at a mud event. Last week I di-electric greased every connector on the bike. Everything worked perfect. Road some deep water and mud today. Now out of nowhere it thru the belt light and went into limp, would go over 3mph, died, and had no power at all to anything. So I removed main 30a fuse, it's good, put it back in, nothing. After 20 seconds went by I wiggled 30a fuse around and got all power back. Reset belt light, rode back to camp. I pulled belt cover, belt is fine and switch is not tripped. So I fire it up. Notice that when I rev it up the cluster would flash and die out then come back at an idle. Well after I revved it twice it went into limp again, and 3 seconds later belt light flashing again. I shut it off, turn key back on, No power. So I wiggled 30a fuse again, nothing. Pulled it and checked it, still good. So i put in a new fuse for giggles and wiggled it. Got power back. My fuse block has no corrosion at all, plugs on the back are clean and tight. Electric greased. So now it's running fine. So I hop on it and open it up WOT down a straight away, no problem. I open it up WOT back and when I slowed down to 5mph speedo stopped working. Just reads 0. So now that means no 4x4. I checked speed sensor plug and wires, cleaned and greased it, plugged it back in till it snapped in place. So I know it's plugged in all the way. Still no speedo. So what gives??? Sensor just died like that?? Or something else causing all the problems.

If the speedo is going blank, then most likely you are loosing a ground connection. On my 05 750, the ground connections are at the right frame next to shifter mechanism, front left frame around shock tower, and I believe there is one somewhere on the engine too.

Ok so I had both fans for my radiator and oil cooler wired thru an automotive relay and then to a toggle that turned them both at the same time. Well after they ran for awhile the 30a main fuse would get really hot and loose it's connection somehow from all the current running thru it. So I disconnected the oil cooler fan from the manual toggle switch and ran it thru an inline temperature switch so it only turns the oil cooler fan on when needed, and shuts it back off after it's cool enough. After I did this I rode it another 8hrs today and it didn't do it once.

But on a side note, the speedo was a loose connection from the kebc delete harness, and 4x4 was intermitant all day. Had to wiggle the 10a fuses everytime it didn't work. Stock fuse box is junk, and I will be ditching it for a waterproof one.

Sounds like you need to go through that entire system from stem to stern.

Here's your answer for a new fuse box. This guy posts these new boxs all over facebook brute force groups. See the link.

That's the fuse box I was looking to get. I have been over all the wiring from end to end. The loose connection for speedo was because of those cheapo wire tap clips they give you with the kebc delete harness to tap into the control box

I used dielectric grease like you did on two BF 750ís and they both developed problems after about 10 hours. Popping fuses. Speedometer cluster going blank. I cleaned it all out of the connectors and used WD-40 instead. No more problems. These bikes donít like dielectric grease in the connectors. May use it to seal the connectors but not IN the connectors. Good luck
