Question about 1980 Honda CX 500 A

2 Answers

I have a 1980 Honda CX500c that was given to me. It is not charging correctly. I keep having to remove the battery and put it on a trickle charger. When I got the bike, I was told that the voltage rectifier needed to be replaced. I have since replaced it, and it didn't help the problem. Can someone tell me what my next step might be?

I would also check the output from your stator to see if the stator is no longer working. You should see a healthy 14 volts when the bike is running above 5000 rpms. If the output isn't around 14, then you will need to replace your stator.

Check to see if your battery is any good. A battery that is no good, will not keep a charge.
That would be the next step, and most likley your problem if the battery froze, or the bike sat for a long time.

Can anyone tell me what and where this plugs into. 2003 Honda shadow 600 vlx.


Looks like a battery charger plug (for trickle charging off-season). Does it always have 12v across the terminals? If so, it's a battery charging plug.

Motorcycle battery charging


Use a trickle charger no more than 2 amps. Initial charge will take 8-16 hours if done this way. The dealership can put a service charge on it which usually takes an hour, but I have found that the battery doesn't last as long this way.

I don't have a manual for my small Black & Decker Smart Charger. I'm trying to charge the battery on my '07 Honda Rebel 250cc. It has settings for 2/6/12 volt batteries. How do I hook it...


Hi,

You just need to set black & decker charger to 12V . Don't make mistake while connecting + / - leads. + lead usually come with Red color cable. You can use the AVO tester to justify the lead cable. The charging time is normally about 10 -12 hours (or just just check the status on your charger display). If your charger does not has trickle charge facility, you have to disconnect your charger after 12 hours continuous use.

Also, you can find the guidance about your charger here :

My 2000 Yamaha golf cart has 6-4cell 8 volt batteries. I did not leave the cart plugged in during the winter months. When I attempted to charge yesterday, the charger lights sequenced but stayed on...


Yes to both questions. the charger must sense 41.5 volts to activate the relay inside the charger. Being a repair shop, I have a charger that is rigged to charge even DEAD batteries. I do not recommend this for the novice. A charger set on 12 volts will bring the batteries back up to 8.2-8.6 volts. A cheap trickle charger may not put out enough to charge a battery of this size. Remember that they are used to MAINTAIN a charge. Connect the Voltmeter and watch for voltage rise. If it rises to 8.1 or above, it is charging. Trojan battery company recommends charging at least once a month.

How do I get to the battery? can I charge it with jumper cables from a car?


Both previous posts are correct. The battery is located under the rider seat. You need to charge it at a low amperage, 1.5 or 2 amps. It will take a while so be patient. Quick charging is bad on the battery. The best bet is to buy a trickle charger such as a Battery Tender and plug it in often. It will keep your battery at its peak. The more your battery drais or receives quick charges, the faster you will have to buy a new battery.

Your battery is junk. Replace it.
Lead/acid batteries lose about 1% of their charge per day, so in 90 days of non-charging they are basically discharged. This is a bad thing. When winter comes, put a smart trickle charger on it, or at least once a month put a non-smart trickle charger on it for a couple hours or an afternoon so you keep it charged up.
I love/hate batteries.

Charging system on my honda cx500c is not keeping the battery charged. I suspect I have a stator problem because they have a history of getting too hot and failing. what do you think?


Hi and welcome to FixYa,

Initially, would have to agree, these bikes are notorious for stator problems. The early models actually have 3 windings to my knowledge.

Good luck and Thank you for using FixYa. Happy Holidays.
