I have a 2006 GSX-R 600 with approx 25,000 kms on it, it is in excellent condition.
I recently went to use it after it sat for 3 weeks and it wouldn't start - dead battery. I charged the battery and checked voltages from the battery with the following results:
Bike off / no key inserted - 12.39 volts
Key in, ignition on, killswitch off (ie: only lights on): 11.9 volts
Key in, ignition on, killswitch on (ie: just after fuel pump has primed): 11.75 volts
Bike running, only just started - 11.75 volts
At warm temperature idle around 15 minutes after starting - 11.36 volts
At 5,000 RPM in neutral - 11.18 volts
I tested the ohms reading on all possible combinations of the stator connector plug. When plugged in it initially showed a number and after a second all went to 0, so I am going with the reading being 0.
I was very briefly
able to perform the unloaded test at 5,000 RPM and saw what looked like good numbers before the bike wouldn't run any longer due to the dodgy battery. I am waiting on a new battery to repeat this test.
I tested my regulator/rectifier and posted the results and members on another forum said that it was bad, so I replaced it with a brand new, genuine Suzuki part and received almost identical results. This would lead me to believe the issue is NOT the regulator/rectifier - am I wrong?
Looking at the data below, does this suggest the reg/rec is in a normal working condition? Or does it suggest there is an issue?
