My ZX-7 won't start :(

Hey guys, first of all let me say that, as my name suggests, I know next to nothing about motorcycles. I have a '92 Ninja ZX-7.

My problems started last week when I tried to start my bike and I couldn't even get the power to come on for the dashboard. I tried jumping my bike with my car and it started up right away, but as soon as I would disconnect the jumper cables it would die immediately.

I took the battery out and took it to Sears thinking that the battery was probably shot. Sure enough the guy got a readout of just over 5 volts, so I figured great it's just the battery. I bought a new Die Hard battery, took it home and put it in. The bike started up perfect, I thought my issue was solved. After about 2 hours of riding the bike just died on me completely at a stoplight and my friend had to come pick me up and trailer me home.

The dashboard still gets power now(unlike with the old battery) but when I try and start the engine, it sounds like its going to start up initially but then it just starts making a clicking noise. Please excuse my lack of knowledge of technical terms for parts, but the clicking noise is coming out of a tiny little box under my seat that has a single 30amp fuse(possibly a regulator?). I took the fuse out and it looked fine but I swapped it anyway just to test and the issue persists.

Does anyone know what my issue is? I'd rather get a solid answer then keep buying and guessing on parts(although I needed the battery anyway).

Thanks in advance and sorry again for my lack of knowledge!

kind of sounds like your charging system isnt working properly. Maybe your R/R is shot or stator going bad. Maybe someone else can shine some light on the subject

Sounds like the alternator is not charging the battery,find the wires coming from the alternator,and trace them back toward the battery,you should find a connector about half way,make sure you have a good connection.Then using a volt meter check voltage at battery,then start the bike and check voltage at battery again,and see if it increases.

Alright so a friend of mine who knows a lot about motors came over today and after looking at my bike determined that the issue is indeed with the stator. I have been looking online for a cheap replacement but the only ones I have found so far are for 1996. Does anyone know if a '96 stator would fit on my '92 ZX-7 and/or know where I can get one for a '92 for a reasonable price?

Thanks again for all the help thus far!

Your bike doesn't have a stator so I'm a little unsure as to what part we are talking about here. Are you talking about the exciter coil?




If so that part was used on the following bikes:



ZX750-J1 (Ninja ZX-7) (1991)
ZX750-J2 (Ninja ZX-7) (1992)
ZX750-K1 (Ninja ZX-7R) (1991)
ZX750-K2 (Ninja ZX-7R) (1992)
ZX750-L1 (Ninja ZX-7) (1993)
ZX750-L2 (Ninja ZX-7) (1994)
ZX750-L3 (Ninja ZX-7) (1995)
ZX750-M1 (Ninja ZX-7R) (1993)
ZX750-M2 (Ninja ZX-7R) (1994)
ZX750-N1 (Ninja ZX-7RR) (1996)
ZX750-N2 (Ninja ZX-7RR) (1997)
ZX750-P1 (Ninja ZX-7R) (1996)
ZX750-P2 (Ninja ZX-7R) (1997)
ZX750-P3 (Ninja ZX-7R) (1998)
ZX750-P4 (Ninja ZX-7R) (1999)
ZX750-P5 (Ninja ZX-7R) (2000)
ZX750-P6 (Ninja ZX-7R) (2001)
ZX750-P7 (Ninja ZX-7R) (2002)
ZX750-P8 (Ninja ZX-7R) (2003)
ZX900-B1 (Ninja ZX-9R) (1994)
ZX900-B2 (Ninja ZX-9R) (1995)
ZX900-B3 (Ninja ZX-9R) (1996)

I might be saying the wrong name for the part, maybe he meant regulator?
