battery

[jamie192]

hi all and thanks for looking.

I have a suzuki ts 50 x and the battery seems to be going flat quite quickly, the other day the part that charges it up wasnt connected properly causing it to not recharge. I redid the connection and its was all working again. That night i charged up my battery and went out put it in, worked fine. today it seems to be getting awfully flat again and i havent riden it much. is there any ways i can tell if this thing is working properly and tell if its charging my battery?

I might have to take it down the garage but i want to try and do it myself because im quite good with electrics just dont know how i would test this thing. O and i have no money.

Get a volt meter and stick it on the terminals while the bike is running. When the revs go up the voltage should go up to maybe about 15v (Kickstart will tell you if I'm wrong ).

If the voltage doesn't go up its not charging, and if it does go up your batterys knackard, if it goes to far (ie 16v+) your regulator is knackard.

Sorry this is short just on my way home.

using voltmeter £2.99 from maplins

connect to battery terminals and with bike not started a fully charged battery will show 12.6 volts (11 volts or below and battery is flat).
With voltmeter connected start bike, voltage should initially drop to around 11.5 volts (any less and a battery cell is to be suspected).
once running voltage should raise to around 13.5 volts.
15 volts or more is overcharging.
the charge voltage (13.5 volts) should remain reasonably stable when engine rpm raised, if voltage fluctuates wildly with engine rpm then suspect charging system fault.

If you think it is required I can explain how to check for current drain etc if you have no luck with the above.

Hi

As above, but I suspect the TS50 might well have a 6 volt electrical system.

Look at the battery. If it has 6 caps covering holes for topping up the water then it is a 12V system, if it has 3 caps then it is a 6 volt system (there is one cap per cell, and each cell provides 2V).

Not sure what the acceptable range would be for a 6V system. However I would say put a multimeter over it and rev the engine. If the voltage does not go up then it is not charging (either the regulator / rectifier unit or the generator), but if it keeps going up
with the revs then it is overcharging (regulator / rectifier unit). I would guess that 7V is the minimun to be expected but over 8V is probably too much.

All the best
