So today i tryed to go for a ride ..bike cranked 2 times than just started fast clicking .. would not turn over.
When I was at harley about 2 months ago I asked them to put a test on it and they said it was Fine no need to replace it yet.. ( I assumed its almost time for a new one its 5 years old )
A friend said I can jump start from my car ???? Is that OK ??

 

I have done it a couple times after leaving my ignition on. didnt seem to hurt anything as far as I can tell

 

Ya ive jumped from car. It screw my tach speedo. It tripped the warning lights off and dealer couldn't reset it. So i had to replace with a new one.

 

i live by the golden rule of NO as i have seen several fried ECM's from jumping off a car... some guys will do it with the car off and that is "ok"... personally i have replaced the ECM's in peoples bikes that they fried from jumping off a car, i will not do it... i put in 2nd gear and bump start it... if not, toss on a battery charger

 

Battery tender is a great investment.

 

It's risky doing it off a car. The battery and ground circuit can't sink the voltage spike if it comes through.
I have done it, but rarely. Too afraid of frying the charging circuit.

 

Charge your battery up from a running car without trying to start your bike: OK

Jumping from a car with the car's engine off: OK

I did the first one, and it only took 5 minutes too.

 

It's time for a new battery. I guess you already Know that.
Cheers

 

What pisses me off about that is ... I was at Harley 2 months ago ..I said hey the bike is an 07 lets change the bat while you have it . They said they put the tester on it and it was FINE no need to spend the $$ on a new one yet
