TLR battery question.

[carlosg7915]

my battery has really low charge. not even enough to start the bike. i disconnected the possitive and she turned right off. is this normal?

Re: TLR battery question.

That's normal, and it's not a good thing to do. (trying to run with no battery).

I take it you jump started it and when you pulled the donor battery lead off it stopped?

Re: TLR battery question.

doesnt that mean his stator is bad? like on a car start it take out the battery if it dies its a bad alternator. same theory here?

Re: TLR battery question.

In theory yes, in practice no.

The charging system on our bikes is nothing like the charging system in a car. (And you shouldn't run a car engine without a battery either).

A typical car alternator is a wound rotor alternator. Regulation is done by altering the current / voltage through the rotor.

Our bikes use a permanent magnet rotor and a shunt type regulator (less load more work for the regulator - same load for the stator. more load = less work for the regulator, same load on the stator).

A Fuel injected TL wont run properly even with a good charging system, good wiring, but a dud battery.

Not enough is generated down low to run the bike.

ok, so charge the battery. got it.

exactly. Im gunna charge the battery all day. once fully charged, how will i know if the charging systems working properly?

Check it. Decosse has a nice electrical system write up. I'm on the mobile, so no time to search for you, but if you read through it, it has all the info you will need, and some extra that's just cool to know for reference.

Re: TLR battery question.

my battery was so low it wouldnt turn the light on nothing. push started it and fine. took the battery off ran fine. but i didnt leave it on forever. i turned it off bc no battery makes me paranoid. now i just have a bike that wont start.....

What Steve said, and...

Disconnecting the battery while a vehicle was running USED to be a valid way to check the condition of the alternator. That was before the days of electronics. With the current electronics the battery also functions to some degree as a filter for the power to the system preventing voltage spikes form frying the electronics. Like Steve said, not a good idea to run with the battery disconnected on anything anymore.

Re: TLR battery question.

this morning i woke up and both my battery's had full charge. i put the yausa on and the bike didnt start. i put the other one on and it wouldnt start it neither. i took it on an 8 mile run with the yausa and by the time i got back i couldnt even press the horn. i took it on an 8 mile run with the other battery and it came back fine. but they still wouldnt turn the bike on. still needs a jump start. should i get a new battery? If a new battery doesnt turn it on then theres sumthing wrong with my bike. // when i parked it 2 years ago there was nothing wrong. just needed the tank de-rusted & a new pump.

found a carquest battery for 72.99. The Yausa ran me $170
