View Full Version : Suzuki NZ250 - Starter troubles, not charging?

I had my Suzuki NZ250 in the shop a few weeks ago for not starting properly, at which time it was determined that the battery was borked and the electrical system was not charging fully when the lights were on, but would just charge it when they were off.

Since then, I've had to put it on a battery charger every couple days to keep it going without having to push-start it (no kick-start, much to my dismay).

Last Friday, I had it charged fully and rode it from the Heathcote valley to Cass Bay, which is about an 8 km trip. I parked it in the garage and didn't touch it until Monday morning, when I discovered that the battery had almost completely drained itself as it was sitting. It didn't even have enough juice for a push-start.

I charged it for 15 or so minutes, and there was enough juice for a push-start. Rode to work with my battery charger in my pack, and charged the battery for about four hours while I was there.

When I went to start it after reinstalling the battery, I found that the starter relay would click when the button was pressed, but there was no other activity. Oddly, if I put it into gear, the starter motor would labor a bit when the starter was pressed, but nothing if it was in neutral. This was a new problem, as of today. I push-started it and rode home.

Tonight, I charged the battery till it was full, and there's still nothing but a "click" of the relay when the starter is pressed. It won't even do anything in gear now, either.

I checked the battery with my multimeter, and it reads ~12.5v. When I press the starter button, it dips a bit, and the output wires from the starter relay read ~10-11v or so. So power seems like it's getting through, there's just nothing from the starter.

Any ideas would be appreciated, as it's looking like I'm going to have to bus it until I can get this fixed, and I won't be able to afford taking it to a mechanic until the 14th of the Month. :-(

Thanks for your time, sorry for the huge write-up.

I just checked it over again with the multimeter, and the battery is at 14v when charging, which drops to ~13v when I take the charger off, and it dips to about ~12.5v when I press the starter, which just engages the relay, not the starter motor itself.

Sounds like you have a drain somewhere in the system, there could be a few places this could happen.

I suggest try disconnecting the battery and with you multimeter on ohms test between the two lead for resistance with the ignition off if it seems low ie in the ohm or kilo ohms ranges then try disconnecting joiners one by one until you find the one that has the short and work back from there, the first on to disconnect is the rectifier/regulator assembly.

From your earlier description, I'd say you have a partially faulty stator or regulator, so you will need them to check over your charging system properly.

Also it might pay to check if there is anything drawing current while your key is off.

If you have no luck keep me posted or get some funny reading you are not sure of ask away, there might still be a manual floating around somewhere for one of these.

That would be extraordinarily handy.

In the event it's a faulty starter or solenoid,
are they typically very difficult to source or replace?

I'm planning on going to the maintenance meet-up on Wednesday night,
but are there any good parts places in Christchurch I might try beforehand,
to maybe have either of those parts ready to go?

Thanks for all your help.

Issue sorted.

Turned out to be the connection of the power cable to the starter.

Undid the bolt at the wednesday night meet-up,
Wayne used a second battery/jump-start box to test the starter, which worked,
redid the bolt connecting the cable, and everything is sweet.

Now to figure out why it doesn't charge very well...

it will be the charging coil?? the NZ we had did the same thing and i bought one of conquistador which fixed the problem, good strong bike ours took a t boning from a car with little damagehttp://i187.photobucket.com/albums/x67/jim157/DSCF2317.jpg
