Thanks! I was going to pick up a volt/multimeter today just didn't have the timeThe battery for sure. Not cranking very fast even at the beginning of the vid. Get yourself a VOM (multi meter) and check the voltage. It should be at least 12.7 volts and when the bike is running it should read around 14 volts if it is charging properly. It may just need to be charged or it may be on it's way out
Okay so I'll just use the multimeter with the bike on. Then use the multimeter after bump starting it and it's idling. Correct?Get that multimeter, too, and check that the voltage across the battery terminals is 14.something with the engine running. If you don't do that, and the real problem is that your charging system isn't, the new battery will not live long.
Okay I will try and do this tomorrow and I will report all the numbersCheck voltage at battery terminals with key off, with bike running at idle and with bike revved to ~5K rpm. Report #'s
Just picked up this multimeter. Before I open in I just want to know if it's gunna be able to do the job.Check voltage at battery terminals with key off, with bike running at idle and with bike revved to ~5K rpm. Report #'s
Alright thanksIt only has to be accurate to one tenth of a volt to check batteries. You can get by with cheap meters if you can test them against something.
Here are my numbersCheck voltage at battery terminals with key off, with bike running at idle and with bike revved to ~5K rpm. Report #'s
Okay thanks."Key off" voltage is low. Too low to start the bike. Try fully charging the battery then retest.
So should I give it a day or 2 to dissipateDon't test the battery right after you finish charging it. There will be a surface charge that takes a few hours to dissipate, and won't give your multimeter a correct reading until it does.

My key off voltage is 12.80 after a 120 minute (2 hours) 10 amp trickle charge. Is that voltage good?"Key off" voltage is low. Too low to start the bike. Try fully charging the battery then retest.
I may have typed down the wrong details cause a buddy of mine set it up for me. (He knows what he's doing) but it was 12.8010A is not a trickle charge and way to high for a bike battery you should be under 2A charging a bike. What is the voltage 2 hrs after removing the charger?
