Pleas Help Me! No Power

Hello all. I am in desperate need of help. I can not get any power at all. I have an 82 yamaha 650 maxim. Well my bike has been running fine for the last week. I got it out and rode it monday for about an hour then parked it in the garage. I didnt mess with it any yesterday. I got home from work today and got it out of the garage to ride, I stuck the key in the ignition turned it and nothing. Neutral light doesnt come on or anything. I checked all fuses in the fuse box. Checked battery on other motorcycle and it worked fine. Looked for wires shorting out against frame and nothing. I am new to motorcycles and dont know what else to do or look for. Please help me. Thanks

 

If you checked out those things the only thing I could think is maybe something came undone from the wireing harness.? Yu take out the headlight and inside you have all your wire connections. Did you try to jump the solenoid? To do that take a wrench or something metal and touch the post on the solenoid for a second to see if it turns over. If it does then it is something further up the line in the electronics. Hopefully somebody else will have some other idea. I don't know much about this stuff either. Hope that helped a little.

 

Did you check that the kill switch is on? It is one of my favourite tricks to leave it in the off position then wonder why my bike won't turn over. Although, I'm pretty sure that the neutral light would still come on with the kill switch in the off position.

 

You mentioned fuses, are they the original glass ones? I ask because I had that exact thing happen once. Fiddle with them and see if it comes back. As soon as you can then replace the whole block. There are several articles on it if you search. If you want pics of the step by step message me and I can show you on the 82 XJ650

 

Yes it is the original fuses. The new fuse box was on my list of things to do. Now sooner than I had planned. Thanks for all the quick replies.

 

xyxj650 I took a screwdriver and touched both posts together and it sparked and tried firing but neutral light still didnt come on. At least it tried firing. So am in need of a new starter solenoid or is something else causing this since it tried firing when I touched the posts together? If I do need a starter solenoid could someone please point me in the right direction to get one? Thanks

 

Is the bike in neutral? Put it up on the center stand and spin the back tire. If it spins but the neutral light isn't lighted, then your neutral safety switch has probably malfunctioned. This will prevent the bike from cranking.

 

gamuru: Yes the wheel spins while on centerstand. If the neutral safety switch wasnt bad would the neutral light still come on when I touch the two posts on the solenoid together? If it is in fact the safety switch, How hard of a repair is it? Thanks

 

i don't think your solenoid is bad I just suggested that as a starting point. But if it ever does go bad let me know. lol i know where to get one. check the above suggestion then maybe look ito the connections or the fuse panel. You have juice but it isn't getting to the ignition. I'll keep looking in to so how this progresses. these guys on this site know a lot of sh*t. I could learn alot by reading what they have to say!

 

The service manual says,

On further inspection of the wiring diagram, I see the neutral pilot light gets its power from the starter circuit cut-off relay. I suspect the relay has probably malfunctioned.

You've tried the first option above (option a), try option b and report what happens.

 

Same thing Gamuru

 

Sorry for the long delay. I went to bed. Okay, to recap, the bike no longer starts with the kickstand up and the clutch lever pulled or with the bike placed in neutral. Furthermore, the neutral pilot light isn't lighted.

From the given clues, we can deduce that either your starter circuit cut-off relay has failed or it's not getting power. According to the service manual the starter circuit cut-off relay is located under the fuel tank (lucky you), so you'll need to remove the tank. It should be hanging from the frame right below the coils. Unplug its pigtail.

With the engine stop switch and the main switch both on, you should measure battery voltage (12+ vdc) on one of the two red/white wires. If you don't, you've got a bad fuse or a broken wire between here and the fuse box. If you do, make a jumper wire and hook both the red/white wires together then try to start the bike again (making sure the bike is in neutral). If it cranks over, then you've definitely got a problem with the starter circuit cut-off system.

We'll stop there and wait for your results.

 

Gamuru, Let me just start off by saying thank you for your help thus far. I really appreciate it. I will try that as soon as I get home this afternoon and post my results. Thanks to everyone and their input

 

Gamuru please excuse my motorcycle ignorance but what does the starter circuit cut-off relay look like? My repair manual should be here next week. I borrowed a fluke meter from work to test connections. I understand touching off on one of the red/white wires but where will my other touch point be? Should It be the positive wire on the starter solenoid? Thanks



Edit: left work early to try and figure this out. There are two boxes under the coils one is black with 4 wires coming out of it. The other is a silver one with two wires. Would my circuit cut off be the black one?

 

You say you have no power. Does the tail light come on? Do the signals work? If everything is dead your problem is with the main fuse or the ignition switch. Jumping that relay will crank the bike even with the key off, all fuses gone and most of the wiring harness burned to a crisp.

I'm not sure which bike we are talking about. Location of electrical components varies by model.

Gamuru, there is an error in the XJ650J,K manual supplement. The relay up by the coils is the side stand relay. I'm not exactly sure which relay is the safety relay. I suspect it is at the rear of the tank as that is the one labeled side stand relay in the book.

 

mjcarl it is an 82 650 maxim. No none of the lights work even when I turn the key on. Its crazy. It ran fine monday and then yesterday nothing.

 

i had the same problem but it was from when I taking my air filter out of my seca i unplugged a single wire. Nothing lit up when i turned the key on. so I looked around the bike and found that and yup... Dunno if this will help ya or not..

 

Then you have an electrical problem that takes everything out.

Check in this order:

Battery has 12V+ terminal to terminal?
Battery + to transmission case shows 12V+?

(all subsequent readings made to ground or battery (-))
Power into main fuse?
Power out of main fuse?
Power into ignition switch?
Power out of ignition switch?

1st question answered NO tells you where the problem is.

 

I had a similar problem the very day I bought my bike. Everything was fine until I pulled the fuses out of the stock panel to check/clean them. They looked fine so I put them back in, but then nothing. Turn the key, and got nothing, just like you described. Went to autozone bought a blade style fuse panel installed it, and everything has been good since.

 

Just got in from messing with the motorcycle and made some progress. I went to autozone to try and find a new bus fuse box. No luck, so I just bought a new 20a fuse. Got home and noticed the fuse that I bought was longer than the original fuse. I figured what the hell Ill put it in anyways. Before I go any further let me tell you about my fuse box situation. I have my main which is a 20a fuse then I have ignition which is 10a and signal 10a but there is nothing in the slot for head lamp. There is however two wires twisted together with electrical tape around them. Ok now back to putting the longer fuse in. After I put the fuse in I thought I would pull the two wires with tape apart. Hit the start button and it tried cranking. Tried turn signals, didnt work horn didnt work. I twisted wires back together tried starting it again. It tried starting then all of a sudden my neutral light came on and my turn signals started working. At least its trying to start now. Everything works but my headlight now. Now what?
