2008 Suzuki king quad 750 fuel pump relay

Recommended Posts



Why would you have to convert to a stronger relay ? 
Is the existing one failing ?
A relay is pretty straight forward except for the manufacture brand, that’s where the quality is. Bosh makes a good relay and a few other brands.

I have3 of the stock fuel pump relays and my bikes fuel pump will not run with any of them.I used a better made relay and it would work for a little while and then it will go right back to not working.

My guess is that the power going to the relay is either not getting the proper voltage  to hold it closed.  Or it’s have a pulsing voltage that’s allowing the relay to not fully close.  

lastly I would check the ground and make sure it’s tight.  

Either condition will allow the contacts inside the relay to arc when they spot fully close and destroy the contacts hence a bad relay. 
So start by checkout voltages first and move on to grounds etc.

      I have a gentleman that asked me to service his bayou for him.  I have always wondered what oil should be used in atv engines?  Pros?  Cons?  What weight should be used in what type of weather?  Is there one kind that I could bulk buy and safely used in any quad I worked on or owned?  What about performance?  Engine Life?  This has always been a 🤔🤔🤔 area for me with quads as far as why you would use one type of oil over another....
      Thanks!

      After looking at the wire diagram I saw the blue w/black stripe wire is coming from the neutral and reverse lights looking for ground thru the neutral and reverse switches. If it finds ground, the lights come on. The same wire also comes from the neutral relay looking for ground at the same neutral and reverse switches. So it was easy to trick the relay into thinking the engine is in neutral all the time without having the light on all the time. Just cut the blue w/black wire at the relay and ground it. Easy
      Sorry the pics aren't better




      Now it starts in any gear and indicator lights work as they should.

      Friend of mine picked up an LT80 that needs some work. The manufacture date is 11/1986
      The fuel and vacuum lines for the carb were all disconnected. I picked up a new card and was hoping someone on here has a photo or knows how the lines are hooked up
      Thanks in advance
