My Haywood Navigator hangs up on newly installed SDXretro drain cover. I tried a Polaris UniCover however the SDXretro has too large of diameter for the Polaris UniCover to seat leaving a side off the floor. Are there any solutions to the Haywood from hanging up on the required entrapment drain covers?

That fuse is under the hood in the main fuse center.

It could be worn shoes on your pool cleaner causing the problem, but it is most likely just that you need to get a ring drain cover to cover your anti-vortex drain. It creates a smoother surface and is designed specifically to work with in ground automatic pool cleaners that are getting stuck on the drain.

Make sure that your shoes and wings are installed properly and not worn. This is the most common issue with these pool cleaners. Improper water flow could also be the problem. Check with the water flow gauge. Make sure there is no blockage in the cleaner's throat and that there is proper tension in the rear flap.

You adjust at the wall the skimmer or at the equipment depending on your system. You will open the main suction all the way then close it down till the pump just starts cavitation and then open slightly. This should have your cleaner moving slow and smooth.

If you have replaced the parts on your pool cleaner, it is probably going to be an issue with the water flow. Check the water flow with your waterflow gauge and adjust it if necessary. See step 6 in the owners manual below if you are not sure how to adjust your water flow.

If it's an older Navigator and it just recently started to hang up on the drain cover, replace the throat assembly, part 29. The lugs or hold offs on the bottom of the assembly have worn down and are not breaking the suction as the Navigator travels over the top of the domed drain cover. Replaced mine and no longer have the "my navigator gets stuck on the main drain" problem.

It's on the left hand side just below the battery or just behind the primary cover of the engine in the rear. it's either a large diameter hose with a tee in it that has one hose plugged or a short section of hose that is plugged onto a large stud on the frame.

On most models of softail, the oil drain is a large diameter hose that comes out down low on the frame just behind the chrome cover on the right hand end of the transmission. There is a plug in the end of the hose. Remove the plug and the oil drains out.

There is a large diameter rubber hose on the right hand side of the bike. At the end of this hose is a plug. The hose ends down on the frame to the rear of the chrome transmission end cover. Loosen the hose clamp and remove the plug to drain the oil tank.
