Hi everyone,



I have a 1980 CX500. I bought it last summer. When I got it, it ran great. About a week later, I had to charge the battery. I put it on the charger for a few hours and it would run great again for a few days. I did that for awhile, because I couldn't afford to get it into the shop. I figured it was either a bad battery, or something else maybe the stator. I finally bought a new battery for it, but it didn't fix the problem. I was able to charge the battery, and ride it for a few days. It was close to winter, so I put it into the garage for the winter.



I went out to get it started last weekend. I put the charger on it (trickle charge) and the next day I went out and had nothing. It was like the charger was never on the bike. No dim headlights or anything. I tried to jump start it, but no go on that either. Nothing when the jumper cables were hooked up.



So to recap, new battery last winter wont hold a charge. This spring, tried to jump start it, and wouldn't start. The headlight wasn't even dim when i had it on the cables.



What do you suggest I look at first?

It isn't impossible to get a bad battery. If the new one has an internal short, even jumping may not supply enough current to crank the bike. Try taking one cable off your battery and hook the jumper up to it and the other battery cable. That will isolate the bike's battery and you will only be using the jumper's battery.



See if anything happens. You may also have a bad connection to the solenoid, or the frame ground. If the bike does start, measure the voltage at the jumper's battery. You should be seeing about 14.5 volts when running about 2000 RPM. If not, then you either have stator or connector problems. Let us know what you find.



Add your location and the bikes model to your profile. You may live next door and I would never even know it.

I would check the main fuse,,by the battery, check the fuse and where it connects to make sure it is making a good connection,,also check battery terminals and where they connect to the bike to be sure they are in good condition and making good connection.

No, I didnt keep the battery tended this winter. Probably should have...



I will check the main fuse, that sounds like a likely candidate. The battery connections look solid. I probably wont get to the bike until this weekend. It's at my Mom's garage, about 10 miles away, and I have a busy week at work.



Thanks for the replies. And if anyone else has any ideas, feel free to post.

Double check for a corroded ground wire, start from the battery and every place it goes. I also converted my main fuse to one of those spade types in a rubber housing.

Lead acid batteries do not like to be stored,"Run-Down".The plates begin to sulphur hence they should be trickle charged from time to time to keep the charge up to help prevent this.

I will definitely check the grounds and the main fuse.



I got the battery from our Local battery shop, Battery Specialists. That's all they do is sell Batteries! But it is not impossible for it to be bad.

Thanks for reporting back,,

Have you had the bike running long enough to find out if it is charging the battery or not?

I have ridden it two days, and it starts fine.



That doesn't really let us know though. Last summer before I put the new battery in it, it would hold a charge for about 4 days.
