charging oddities
« on: March 25, 2007, 08:33:38 PM »
OK so my charging system may be boinked, I sure hope not.  I checked my batt and found it was quite low on water, I seriously need to get a gelpac or something!  It was about half full.  I was too excited to finally go for my first ride and forgot to check it. rode about 40 miles and was at a stop sign and my bike died. Elec start did not turn at all. Well I kicked it and got it going and rode the 5 some miles back home. Upon testing, with key off, I was around 11 volts, key on dropped to like 9 something. Not very good. Started it with kick and revved to 5000, no load as in honda manual, made it to about 11.5 volts. ok Now I am a bit torqued!  Went in and ate and went out to do a little tshooting.  Filled batt with purified water, cant find charger though. However, when running and revving the engine, voltage slowly climbs and I got it a little over 12 volts now. Better but not quite enough.

Now I have had the batt a couple years now and it was a cheapo, walmart things as I did not have enough to get a good batt. Bike runs ok and I wrung it out some and hit 60 in 2nd gear! :o  In town...in a 40 mph zone! So it seems to be getting its spark.
But I was only gone for a couple minutes and thats it.

So my first Q is this, With the batt being low on water, it may need to be replaced or will it just take a bit of time on the bike to charge? 

Second, in the event that it is the charge system, I need to do tests. I no longer have access to a good fluke tester and no funds to get one, especially if I need to get a batt, is there ways to test for continuity with a cheapo tester? I have a cheap 10 buck thing and it is relatively accurate for volts and ohms. Can I do  modified test to do continuity?

You've probably seen this, but here it is regardless:

http://www.dansmc.com/batteries.htm

I hope by "purified" water you mean distilled water.  Purified is relative - distilled absolute.

Even an inexpensive multi-meter should be able to give you a continuity check.  If the meter has a battery it should do continuity for you.

Some meters without a battery in the meter itself, will check continuity - but they have a battery in the actual lead line.  I say this because I've come across such meters at yard sales and auctions.  It's confusing because the meters have ohms on the dial, but the meter is missing the lead, so won't work for continuity.

Decent little multi-meters come up for sale often in the 10 to 15 buck (Can) range.

Well I long lost the scant instruction sheet for this thing. I think others here use it. It is a cen-tech. CHEAPO! So just switch to ohms and it should manage? 

The dans mc site is not coming up right now so I cant check it out. my batt has floaties on the top of it though and I think 1 cell has some junk in it. Might need to replace. My goal is to test some things on tuesday and if they pass, get a new batt.

Being honest the battery is 95% toast. when i serviced them regularly it was surprising how much the level went down in 1500 miles---Having said that never buy an ex mechanics bike-----by the time you get home you can rarely be a***d to look at your own!

after a while of thinking about it, I think it is the batt.It kicks over very easy. Barely a kick even actually, I mainly just turn it over and it fires, it runs fine and everything. the batt just does not take much of a charge. But you know how it goes. something happens and you have that period where you want to freak cause you want to ride and not work or you just dont want a problem!

SO I am going to get a new batt. I would like to get a gel or agm battery. Any good places online that are fairly cheap?  Heck even an MF is better than the standard basic!

I got an AGM from Advanced auto, it was under the wrong item number aqt 3 locations though, if they say the $65 isnt available have them check the shelf for a similar number and they'l find it as long as the k6 battery is the same as your K8 may not be so disregaurd my comment   ;)
