Question about Motorcycles

Why does the 30 amp circuit breaker behind the battery box on my 1990 fatboy click once when i push the ignition button? The bike won't start.

Bike won't start or clutch start. All that happens is a single click sound from circuit breaker (30 amp) behind battery box.

    Ive now taken the solonoid cover off and am using a screw driver to push the rod inside across to engage and turn over the motor. in the primary, all i hear is a grinding sound or a click. sometimes i hear the oil moving about the nose cone but not enough turn over to start the bike

  • Michael Green Apr 20, 2012

    If you can hear a grinding sound when you try to turn over the engine, The most likely problem is- either the drive gear on the starter motor, or the drive gear on the transmission. It could be something as simple as the starter clutch not engaging properly. The starter motor winds up and this causes a gear to engage with the transmission drive gear. If the clutch is not operating correctly the gears won't mesh properly and you will get a grinding noise. I hope this points you in the right direction.

Try to reset the circuit breaker. also check for an earth fault on the starter motor .If this is not a circuit breaker and is a relay, you should make sure everything is ready for a start, (ie : in neutral, sidestand up and clutch in and that the battery is charged.) the neutral light being "on" doesn't mean it is in neutral. I hope this helps.

SOURCE: bike wont go into gear, just had a new clutch put

With bike not running, rock the bike backwards and forwards and shift through all the gears. If it shifts all the way to fifth gear and back down, then the problem is not in the transmission. If you can't shift the transmission into any gear with the bike not running, just rocking it backwards and forwards, then you've got a problem with the transmission or the shift lever mechanism.

If it does shift but you still can't get it into gear something is strange. I've seen a clutch that the plates were locked together from sitting up, but it still would shift into gear. Of course, when it did shift into first gear, the bike would lurch forward and kill the engine. In this case, we had to disassemble the clutch pack and free the plates up. If you've had a new clutch put in the bike, it could simply need an adjustment. But, usually a new clutch will have a tendency to wear in and start to slip rather than drag. When a clutch causes the bike to lurch when put into gear or become difficult to find neutral with the engine running, it's dragging. I'd check the entire clutch adjustment to start with.

Slide the rubber boot on the clutch cable up, break the lock nut loose and turn the adjuster to make the cable as short as possible. Take the derby cover off the primary to gain access to the clutch release adjuster bolt. Break the large locknut loose, adjust the center bolt inward until you feel resistance. Back the screw back out and back in until you feel resistance again several times. You want to just take the slack out of the adjustment, not start to open the clutch up. Once you've turned the bolt in and feel the resistance, back the bolt back out 1/2 to 1 complete turn. Hold the bolt in this position and lock the lock nut again. Now, adjust the clutch cable back out until you get a freeplay of about an 1/8 inch at the lever. The clutch should be adjusted well enough to release at this point. If it doesn't, the clutch plates are probably stuck.

If the clutch plates are stuck, rock the bike back and forth and shift the bike into fourth or fifth gear. Now, while holding the clutch lever in, push the bike backwards and forwards far enough to "bump" the clutch. This may break the bond between the plates and free it up. If not, you'll have to disassemble the clutch in order to free it up. Good Luck.

SOURCE: how to wire for a hitch behind the bike for a trailer with lights

Wiring a motorcycle for a trailer is exactly like wiring a car or truck for a trailer hitch. You have to determine what type of lights you want on your trailer. You brake lights, turn signals, and tail lights. So, you get yourself a test light and connect the alligator clip to a good ground.

Now, on the backside of your rear fender is all the wires going to your brake light / tail light assembly and your turn signal lights. Now, I don't have a schematic for a late model FLH but it used to be the red wire was the brake light, the green wire was the tail light and you had a brown wire for one turn signal and a purple wire for the other side. The turn signal wires were actually gray wires with little brown or purple "bands" around the wire out near the bulb.

Step on the brake and use your tester to probe the wires until on lights up. Release the brake to verify the correct wire for the brake lights. Now turn on the right turn signal and probe the wires until you find one blinking. That's the right turn signal wire. Do the same thing to find the left turn signal wire. Now, you shouldn't have very many wires left. So, turn on the headlight and probe until you find a wire that lights up the tester. Now, at this point you should know which wire is which on your bike.

The trailer should have come with a wiring diagram. If not, you'll have to look at the light sockets on the trailer. You should see at least four colored wires. There should be one color wire on one light that is not on the other side light. These are turn signal wires. One color to the right, one color to the left side. Now the other two colors should go to both lights. One color is the brake light wire and the other is the tail light wire.

Now, that you have all the wires identified, simply buy the little connectors and start connecting the proper wires to each other. You'll be trailiering in no time. Good Luck and ride safe

SOURCE: 2002 Harley Davidson Electra Glide FLHTPI loses all electrical.

Professeur D is another of the people who just can't say "I don't know" or just be quiet. His comments are worthless. You don't say what the bike model or year is, but I bet it's a newer bike. I have an '02 FLHTCU with the engine juiced up a little and the rear cylinder really runs hot. The circuit breaker is located right over the rear cylinder, and since I have an oil temp gage I can see that when the temp hits 230 the breaker is going to open and shut all electrical off. I've changed breakers many times and the problem is still there and the dealers don't know what to do. I've been told by another rider that I should replace the circuit breaker with a fuse which will not be affected by temp. I'm going to look into that!

Headlight on 1995 fatboy won't work is there a fuse? Where is it located?

Hi Tim, you need to get out your test light and find the short and start by making sure the battery has 12 volts or more and clean tight connections especially the ground cable at both ends. If your issues involves lights always check the bulbs for broken filiments and fuses first. Then start at the socket and work your way towards the handlebar switches checking each wiring harness connector for corroded, broken or loose pins and remember dielectric grease is your friend. Check the switches for continuity and work your way towards the ignition switch and check it for continuity. Keep working your way to the fuses and circuit breaker and finally the battery. On a Softail remove seat and directly behind the battery is a black plastic box. The cover slides up and off revealing the starter relay and the system/fuel pump relay for you injected folks and the various assorted circuit fuses.

I was riding my bike running great went to store turned off the key when i turned the key back on no power to the lights or instrument panel. i checked all fuses. it has good battery. i arced the starter...

Locate wire block at ignition switch, using a test light or multimeter check red wire for 12 volts dc, if you have no voltage here, you will have to trace the wire back to the battery and fusebox some models have a circuit breaker on the underside of the battery box, or in the imidiate area, its a 2 wire breaker with a transparrent cover and a red dot in the centre, push at this point to reset, have you checked the fuse at the solenoide 30 amp, if you do have power at the red, turn the ignition switch to the park position as the bike has a seperate live to the rear light, it should light(this will also proove you have power at the ignition)

My 1993 1200 sportster did work fine till I had to lay it down quite hard. after laying up for a couple of months I started to put it back together.first of all I got idiot lights but only click on pushing...

If you've got circuit breakers tripping, you've still got a short somewhere. Pay particular attention to either of the handlebar switch housings. There are quite a number of wires running to each side and any one can easily be pinched and cause a short. I'd focus on the right side with the "Run-Stop" switch in it.

Good Luck

Bike ran great all day. Turned it off but when I went to restart, no power at all. replaced ignition switch. short in system somewhere but can't locate it. Start button kind of clicking like it...

You didn't say what year or model bike you're working on. The clicking you're hearing could be a circuit breaker tripping. If it's a soft click like a turn signal flasher clicking, this is probably a circuit breaker or a relay. If it's a loud click, it may be the solenoid on your starter. Does anything else on the bike work? If not, it's probably the main circuit breaker. How about any security system that may be on the bike?

Good Luck

Harley won't start ... starter not working custom softail ... 80 ci v twin engine... nothing happens when I push the starter button.... battery is fine and all lights work... clicking sound under seat...

That clicking sound you are hearing may be a circuit breaker tripping indicating a short circuit somewhere. I think the starter circuit is powered by the ignition circuit. If you have a short circuit in your ignition system the breaker will trip killing power to your ignition, thus the engine dying, and preventing power for the starter circuit preventing the bike from being restarted.

On your bike, I believe there is a chrome coil cover over the coil on the left side of the bike. Check and see if this cover has come loose. I've seen them come loose and fall down on the coil connector on top of the coil shorting it out. If that ain't it, just keep looking, there's a short somewhere. Good Luck
