Checking charge voltage

[DryRob]

My battery's on the way out and wanted to check for bigger problems before I stump up for a new one.

I know it's a long shot but is there any way of checking the charge voltage on a pointy without removing the seat?

I need to bump mine off at the min and could do without giving the neighbours a laugh if/when something goes wrong when I jump on the loose seat.

No, you'll need to do several tests to see if the RR is on the way out.

Check the fault finding how to in Geodude's signature

its very very rare that the pointy RR gives up, what can happen is that the connectors from main loom to RR fur up and need cleaned as they are those naff water proof (also keep water in) type connectors.

you cant check a charging system with a fubar battery so you need a good battery.

how old is that battery?

why dont you want to take the seat off? it only takes two mins. your going to have to take it off at some point.

I'm being lazy to be honest and seem to remember someone telling me you can measure the voltage from the alternator, suppose he could have being having me on.

The battery's 9 years old so it's probably just had enough and been killed off by the last winter.

Would it be worth buying a charger to see if i can save it?
I'll probably need one over the next few years anyhow, the bike's more for fun than transportation these days

The only way to be sure about the battery is to take it to a place that has a ,"Load Test" battery tester,or it used to be.

However if you are looking for a decent maintenance charger I use an Oxford 601 which also has a dead battery check function.Around £30.

The only weakness with the type of charger is the cable over time can wear through flexing at the box junction but I've cured that with a Tie-Wrap,



PS
I've used this charger to charge a flat Car battery but because it's only low output(600 mA) and a,"Step" charger it took three days

Saving a 9 year old battery is not a good idea, they don't normally last 5 unless they are very well looked after. Cut your losses and get a decent battery now, and remember the sour taste of bad quality remains long after the sweet taste of low price. Buy cheap and you buy twice.

When you get the new battery write the date you bought it on the case somewhere (even if you have to stick a label on to write on), it helps in the future as our memories are never as good as we think they are.

as others have said. 9years out a battery, well done but its now fubar. there is no recovering it as the internal plates will have warped etc.etc.

buy a new battery.

dont be tempted to charge a new battery. put the acid pack in and leave the battery for a good 12hrs before fitting it to the bike. after that the bike will keep it charged every time you take the bike out for a ride.

I got a new Yuasa over the Christmas holiday, and the instructions in the pack specifically stated to add the acid pack, leave it for 90 mins to 2 hours to 'settle', then to charge the battery for 8 hours or so at the stated charging rate before fitting.

I have tried that with Yuasa batteries after adding acid and leaving to settle and got a green 'charged' light on my charger after less than 10 minutes. The battery started the bike absolutely no problem as well.
