No juice after turning on key

#1 Post by cyclonel » Wed Jan 31, 2007 2:28 pm

Hi,

My bike has been sitting about 3 months.
When I turned the key on nothing, checked & replaced the battery, no go.
Everything was fine the last time I started it.
Where to look & what to check?

Regards,
Ron

Hey Ron - first off... welcome to our community..!! :smile:

Now, when you turn on the key, does the headlight come on? Do the power valves cycle? Does the horn honk? Have you checked all your fuses?

You say it's been sitting 3 months - have you performed any maintenance or other mods during that time? Anything? :-?

I have an 84,no spark,lights attempt to come on and power valve pulleys lethargically turn ,new battery ,run down will charge out of bike tonight 2 amps .This after having been idel for 6 weeks ,started 1st kick last Friday night,rode it Saturday,ran outta gas ,put fuel and rode it home, next day nada.all conections seem fine ,suspect a short were the tank meets the positive side of the battery. My question is if that's the matter what generally gets fried first?

Roadtoad32....

The 2 weakest links in your 84 RZ350 are the CDI and the stator. Both problems are very well known and very common. The CDI won't affect your battery. The stator will. Typically the CDI failure goes like this: the bike will run fine for a while until it gets warms, then the CDI will start to fail due to a cold solder joint and eventually the bike will simply die. Once everything is cold again the bike will start and run briefly until the CDI gets hot and starts acting up again. Sometimes it will just quit and that's the end of it. The only way to test the CDI is to try a different CDI. A stator failure will mean no spark and no charging. If I were you I'd start my metering your stator. It's very easy to do and takes just a few minutes. The only way you'll sort this out is by eliminating the obvious. And as for the battery, well, it can be dead flat and you should still have spark when you push the kicker.

Also....you may find it better to seek help on the 350 side of the forum. You can always PM me as well....on either forum. The 350 is where I spend most of my time and I've been around the block a few times.

Sure. PM me your email address and we'll get it sorted out. If you can work the meter and know what resistance is you can do the test. There are only 8 wires to check.

Do you have a manual? If not, I'll email you one.
