best battery for bikes image
Candace
I trickle charged the battery on my bike and put the battery in just to see if it would start but I didn't tighten the terminals. The dash lights turned on and when I went to hit the ignition, it sparked and then absolutely nothing. The dash lights will not even turn on now.
No fire! I didn't fry anything did I??
Thanks guys! I got it figured out! Just needed it to be tightened and it was able to start.
Answer
If you didn't tighten the battery terminals:
The small area of metal contact between the battery post and your battery clamp carried the small amperage current required to light your dash lights. When you engaged the small amperage circuit running to the starter relay it had enough amperage to momentarily close the relay but when that high amperage circuit to your starter closed that high amperage load heated the small contact area between your battery post and battery clamp melting the contacting metal area and leaving oxidized metal behind.
When you remove and wire brush the melt pitted and oxidized affected battery post and clamps and firmly tighten them all should return to normal.
When finished buy some battery terminal sealer, it's no more costly than a can of spray paint, less frustrating and messy than smearing grease over the posts and clamps and if you watch it will make water bead up around the terminals instead of soaking in or dampening the post / battery area.

How do I check to see if my stator is working?

I have a 1982 Nighthawk 650 and the battery isn't getting a charge. The stator is new as well as the battery. The bike has been dormant for almost 2 years so the battery is questionable. I can jump it but I think it's just running off the battery. How do I check to see if the stator is putting out?
Answer
This simple series of tests with a voltmeter across your battery terminals will give you some insight into the health of your battery and charging system. Charge the battery an let it stand for an hour. A good one will read 12.6-12.8 v. (I know you have a new battery, but they have been known to be bad right out of the box.) Crank the starter. Your battery's voltage reading should not drop below 10 v. Once your bike is idling, it should read somewhere in the neighborhood of 13.1 v. The exact figure is not important, but it should be significantly higher than the voltage at rest. As you raise the revs, voltage should increase to around 14.1-14.5 v., at which point it should level off or drop as the regulator shunts current to ground.
