Harley Davidson starter problems troubleshooting

If you push the start button on an older form of Harley fuel tuner and you hear a clicking sound, there are a variety of things that you need to try to find out what the problem is.

The first thing is to do, you have an ultimately charged battery and let us go back to the start button again to push the hear button. You hear click-click; what you hear is on this bike on the right side. It is a very cheap starter right here under the cover, and they use them almost anywhere on the front.

It is a primary relay almost, all the same, is that you pass some shallow current through to some high current senate pole is not used for anything, so you hear this relay picks through the connector that’s inside wires through the thick cables on this bike in the thick cables.

The red wires flow down here through the frame, and over here is the red wire from the initial reeling. If you have 12 volts here when you push, the main possibility is that you have an issue with us with the solenoid here; what happens to the solenoid is when you get 12 volts here, you feed the coils kindness cover that pulls down the plunger to some contacts.

If you don’t go back again, follow this redback through the frame to where you have another issue with this connector is that Carley placed a very thin black white here as a ground.

The red wires flow down here through the frame, and over here is the red wire from the original reeling. If you have 12 volts here when you push, the main chance is to have an issue with us here with the solenoid; what happens to the solenoid is when you get 12 volts.

Here you feed the coils kindness cover that draws the plunger down to some contacts in the background where there is one worn contact out here. If you don’t go back again, follow this redback through the frame to where you have another issue with this connector is that Carley placed a very thin black white here as a ground.

This wire is the wire used by the Harley Davidson fuel management system, it is a very thin gauge wire, and it oxidizes and does not have a reasonable, grounded time, so you can still not get enough current flow even with a meter to get 12 volts reading so you can replace the ground wire with a heavier 12 gauge to the connector and solder both ends here.

Now what you have is a stable ground from the relay that you can replace the relay and then obviously a repaired and the solenoid, so now it’s a new relay when you push the start button can get a good transfer. These contacts are pitted so that you do not get enough flow through the relay and through the black wires that continue it and get a nice one.

You can get useful contacts through the plunger because new connections have been rebuilt, so there are three or four places that are normal to fail. The one that got me was the groundwater because I discovered how to restore this, and that did not solve the issue of how to replace this that did not solve the problem, but the catch provided a better ground.

Harley Davidson hydraulic clutch lever replacement

Before removing the clutch lever as you have to get down at the adjuster. If the clutch lever is stock or aftermarket, it is very similar in working that depends. But usually, you will get a lock nut, and you will be going to remove the lock nut as well as you will be going to the lock nut that is responsible for locking everything in the place. With the lock nut removal, you go to the bottom, and here you will find that there is going the actual adjuster net. Now you should keep tuning it that turns it in. this turning will loosen the cable that will provide some opportunity of flexibility up to the top for replacing the clutch lever.

Now you should adjust as far out as you can go, then you may well be able to see up the top that will offer you a whole bunch of playing all of the ways in on that clutch lever. There has a pin that holds the clutch lever on and goes through the clutch lever. You will see there have snap ring pliers on that pin’s bottom, and that pin is the snap ring that it should remove. With the removing of the snap ring, you should just be pushing up, and you will grab it from the top of the lever. You will be over the top of it that you can pull that pinout, and the cables lose it depends on why you want to loosen it. You will be tugging out there at the sleeve that provides you some room there, and then you can remove the clutch lever.

Then there has always one plastic pin in here that holds the cable into the handle of the clutch that rights out in the backs, and after that, the lever will be free as everyone states whatever you will be here. But if you have not done it correctly or in a while, you may want to have some lube; those are just hearty lobe as well as lube the cable up when you are in there.

Now you can use the same plastic pin to put the new clutch lever on, and you can seat that pin down in the place. Then you can just work on the cable again as before you have lost the cable so that you can work on it here. You can see that this pin is not gone through the cheeks.

It is one type of hang-up, so there has a trick that is to pull that is pulling the whole clutch cable and using a lot of force. Now you will be able actually to pull it out, and then you can seat this in the end, and you will be going back with the stick metal pin to line everything up and put the snap ring on and going back to the underneath of the bike to get the pin back. Now just put the snap ring to the back on and take the mirror to put it back on. It would then be best if you took the half inch acorn nut to the bottom of the lever, and the last thing you need to do is the slack out of the cable.

Now you can push it all of the ways to leave it like the way you can be looking up at it when you are adjusting this out that will make tension. You can just down and can watch it up. The way mostly uses in the shops you can adjust it in the same way. However, if you want to feel your clutch but the starting point and a good standard for adjusting, it depends basically on a quarter-inch of playing. You can put it on the clutch lever before you feel that the cable gets tight.

You will bring about a quarter inch in the right, and it is a good place for starting. You will get the clutch lever adjusted up to the top exactly where everyone wants it. It will be best if you took the lock nut and set that in so that this lock nut does not fall out to adjust to grand on and turn opposite directions through the wrenches.
