I recently picked up a buell xb9r August. Was having title issues and I let it sit on my porch at my apt for about a month. Once that was figured out I rode it every other day for another month and it started clicking when pressed start. Then it would catch and go. So I bought a new battery and it died after sitting in my parking spot in just 4 DAYS. Got it charged up by autozone and it only lasted a couple days too. Went back to autozone got a new battery and never installed it. I was gonna go to my buddies place today to use his volt meter to find the possible parasitic drain. But after I installed a fresh new battery, the bike makes the machine gun clicking and doesn't turn over. I'm lost on what to check. The connectors are pretty tight on the battery, no fuses look blown, and switched the relays around. Any pointers?
New to me 03 buell wont start

Welcome........... Your about due for a stator and vr replacement... And while your at it replace your 77b plug...

you need a base-line to start from. take a fully charged known good battery and install it. hook up both cables and let sit for 10 minutes. unhook negative cable and place voltmeter on DC amps. install voltmeter in series between negative cable and negative battery post. should have reading of maximum 0.25 amps or preferrably less. if you do you do not have a parasitic drain. reattach negative cable and try to start the bike. if it starts let it generate a bit of temperatue then set your voltmeter to DC volts. at 2500rpm with a fully charge battery you want a reading of approx. 13.1-14.3 volts DC. if so charging system fine. if not post back for trouble-shooting.

remove front pulley cover.....3 torx head screws. you'll see several large plugs. follow the cloth wrapped thick sheath back from front of motor, beside oil lines, and to its respective plug. THAT is the #77 charging system connector plug.

So I had a local guy from the forum, thrstrmech, stop by my place to diagnose the problem. He happens to have the ecmspy. Ran the spy and found no codes thrown. We broke Down the bike and checked every wire and they are in pristine condition. Had to use another battery to run ecm btw. Even with a fresh battery, it didn't start. r Suspect the spark plugs and wires could be replaced. Possible its not getting a good spark. So well try next weekend. Just keeping you guys updated
understand the hard starting being the plugs and or plug wires, but the clicking (solenoid) and low battery issue is probably a charging issue. May want to check the grounds also.

yea, mentioned the solenoid as possible problem. Should have brought my multimeter and checked the circuits. May have helped to narrow down the problem.

I'm currently doing the stator/regulator test. the stator gets a zero read when I place in each socket with a good ground. I'll take it on a quick ride through my apt complex to see if it charges. Went around the block. The battery before ride was 12.44. Then it shows at 12.38 after quick ride
I'd say yes. if your battery is new & it doesn't keep voltage ~13.8 then it's a charging issue.
Just let me know, I have known good stators & motor parts at fraction of new prices. & I can ship priority so you'll have it quicker unless a dealer has it in stock.

I'm trying to diagnose the problem not buy parts. Ide rather get it figured out than to throw a band aid on it and hope it works.
So far I've done:
**the voltage regulator test.
-passed
-no trouble light turned on
**milliampere draw test
-got a -16.8 draw, so I'm under the requirement
*************
Has anyone attempted the total current draw test?
I'm a little confused on how to do it especially giving it gas and testing the draw...

Ok, you already found the problem; 12 volts at the battery when running then less after a short ride. It's not charging.
Charging system OR
Wire harness at steering neck sometimes breaks or shorts or you have a loose connection some where.
Are there a lot of accessories on the bike? Draining battery? Speakers or something hardwired to battery?

that is correct.
now that you understand the charging basics and know how to use your multi-meter you need to identify the guilty culprit. do as follows: look in your manual and locate the alternator(called stator in manual) plug. set meter to AC VOLTS. start bike. put meter leads in plug. start bike. you should see something in the vicinity of approx. 47-51 AC volts @ 2500rpm. these are close approximates. do you? alternator is fine. if that's the case in all likelihood the voltage regulator is bad. check your manual for ohms testing of same.
