Need Help!!

[fzrlero]

ok, two nights ago i went to O'Reilly's to buy a new battery so I could make it home from work, the guy working quickly gave me a battery and locked the door as soon as i walked out. the battery he gave me was wrong (backwards terminals) it was 9 at night so I couldn't see so I just assumed that for once I got the correct part, hooked the battery up and bam, spark, then nothing. bike has no power ANYWHERE..gauges do nothing, starter doesnt work. when I try to push start the bike the gauges will light up but I'm not getting any fire I assume. It blew the 30a fuse by the VR so I replaced it and still nothing..please help my bike in 30 mins away from home in an unfamiliar apartment parking lot...

edit: bike is a '91 FZR600 with no aftermarket mods

thats the only fuse? did you check em all? might have messed up the battery im not sure if you can by pluging them in backwards. got a friend with a truck? dont let it get stolen!

[fzrlero]

thats the only fuse that blew, I'm not to worried about it getting stolen I talked to the owner of the apartments and she let me park it on her patio but I'd rather not let it sit for a while..the bike is mint and always garage kept, I would hate for it to go downhill..I also have a correct battery being delivered wednesday morning. but I tried running it off my cars battery and still got nothing..

[apsolus]

maybe you fried the computer, does it at least turn over?

[fzrlero]

it doesn't do anything. it doesn't click when I turn the key or press the starter, no lights, its like the key isn't even on. I was leaning towards it being the ignition switch for that reason but haven't thrown the computer out of it yet, what about the VR? what would that effect if it went bad?

[kilika2]

I know you said you checked all the fuses. But double checking. The 2 next to the vr and then (assuming 91-95 are the same) like 4 next to the tdi? It's 50/50 if the bike will start with out vr. It's bad for the tdi if you didn't fry it already. Also check to see if you arced the harness to the frame anywhere.

my bike only has one next to the VR, a 30a that was blown, I replaced it and it made no change. but there are 4 by the computer all of which were fine (I replaced them anyways for peace of mind) I looked over the harness in a few points but I was on my lunch break and didnt have much time, I'll check it out further tomorow. would a fried computer make the bike act like it is? (completely dead) I would like to be back on the road by wednesday..

When you push start it and the gauges light up does the headlight come on too? Also just to eleminate everything when push starting you have the kickstand up. And before push start you have bike in neutral trying to start it. Finally check your coils for melted wires too.

But to answer your question yes a fried tdi can do just about anything.

Hi,
i thought we had a whole diagram of electrical trouble shooting flow chart for this situation in the WIKI

[fzrlero]

yes, when I try to push start it the headlight glows but I can never get the bike to fire so it doesn't come on fully. I guess I dont understand the 2nd part of your post..I've tried to start it in 1st with the clutch in, in neutral and with the kickstand up and down but nothing helps. the bike gets no power anywhere unless I push it and even then it wont fire.

thanks George, I'll take a look there and see if I can figure it out

I took a look at the diagram and now I'm starting to think its the ignition switch or the VR, both closer than the CDI. at least I'm hoping its one of these..

[kilika2]

You answered my question. I just wanted to make sure you had tried starting in neutral not just in gear with the kickstand maybe down. Also I'm including a link to Yamaha George's website. In the pic there is the fuse to the far left and then the 2 relays did you check them too. Just curious. I'm about out of my knowledge to help you too. Haha. We need Mawler on here to help out . Haha.

No, I havent checked the relays. IIRC one was for the HL so I didnt think anything of it..I will check them when I get back out to the bike today

[kilika2]

One is for sure the flasher too. But in my experience if something in the circuit is grounded when it shouldn't then it will jack everything up. Just killing off the variables.

Just let us know.

That tells me, the wiring, and Ignition switch are fine, also the VR is working (it could be damaged though). There’s no way the Stator/VR alone will fire up the bike, I suspect.

1. He’s trying to push start with either the dead battery, or no battery, if so the only power source is the VR, which as I said won’t fire the bike up.

2. God forbid and unlikely he has the new battery connected in reverse polarity.

Since he has no power when jump starting, yet there’s power when push starting. Logic tells me there’s an open circuit somewhere between the battery positive and the VR (Red wire). The same Red wire also connects to the Ignition Switch, feeding the whole electrical system.


1. What’s the voltage of the car battery?

2. With the car battery connected, take a voltage reading @ the Red wire on the VR, it should be near battery voltage.

If  there’s no or too little Voltage to the Red wire (VR side), there’s probably an open circuit/bad connection between the battery positive and the VR, which includes the Main fuse, or a poor battery ground?

When connecting the battery wrong (reverse polarity) the VR can be damaged causing the Main fuse, when it’s replaced to blow instantly. Recheck the fuse, if it’s blown the VR is toast.

Never run any vehicle without the battery connected, the Regulator will get overloaded/damaged causing an overcharging system, we all know what that leads to. When the bike does start, first an foremost he should check the charging rate (with no load) 13.6 – 14.4 volts  @ 3000 RPM. His lights are permanently on when the Ignition switch is turned on, therefore remove the headlamp fuse to gain an accurate charging rate (no load).


just quoting :-oopnorth

thanks for the help everyone. I found the problem, it was a bad connection running into the 30A fuse..Should have my new (correct) battery tomorrow morning. if they didnt screw up again that is..
