Follow this info you should be able to do it on your own just buy a multimeter if you do not have one
As stated set it for DC, probably 1-50/60volt range. Red is positive.
First with the cables connected and every thing tight, with the battery fully charged.
Test across the battery terminals with the ignition OFF. You should read 12.4v-14.7v.
If you're not in that range, there's a problem with the battery. Turn the ignition ON,
Testing across the battery terminals again, should slowly drop to no less than 11.4v
over at most 30 seconds. If it passes that hurdle (and it should with a new battery),
To test if the sitting battery has an excess discharge rate while turned off.
First, dis-connect the NEGATIVE cable to the battery and set your multi-meter to
read ohms. Hook the probes between the negative cable on the bike and the battery's
negative terminal. Leave the positive cable hooked to the battery for this test.
With the key OFF, you should read NO MORE than 1.5 milli-ohms. If you read more
then you have either, a short in the harness or a short across the battery (from
dirt/electrolyte on the top of it, again not likely with a new battery), or a bad r/r.
Try that first and see what that tells you. After that, it's probably a charging issue.
If it doesn't challange you it won't change you
