i had a thread a while back, probably 2 years ago, about a regulator/rectifier that i thought was going bad. i got sick of working on the bike and went out and got a leftover 07 gsxr. anyway, its been sitting in my barn for 2 years now and id like to get it running again. since the weather is getting nicer and not so hot i figured id start working on it. i got my manual out and it has a walk through on how to test if the regulator/rectifier is bad. i ran through it and sure enough it failed both tests. ill skip 1-3 as they're taking off the side covers and stuff 4. connect the positive ohmmeter to the yellow terminal and the negative lead to the to the green terminal. there should be continuity (low resistance) 5. reverse the leads and repeat 4. this time there should be no continuity. 6. connect the positive lead to the red/white terminal and the negative to the yellow. there should be continuity (low resistance). 7. reverse the leads and repeat 6. this time there should be no continuity. 8. if it fails any test you're screwed and have to replace it. 9. if it passes consider yourself lucky, but keep looking. thats obviously not word for word but close enough. does this test seem accurate, or can someone else run through that test to see if it works on theirs? i find it hard to believe that it can fail both tests.
a better, more reliable test is to measure stator output with engine running at various speeds. If there is good voltage (about 8-60 AC volts depending upon rpm), then the regulator is responsible for your problem.
the only problem with that test is, it doesn't start and run. if i gravity feed the carb itll run but the fuel pump isnt getting enough voltage to run i guess. i hooked it up to a 12v battery and it works fine.
Use gravity feed, either fully recharge your bike battery or hook up car (not running) battery with jumpers, test again.
ok ill gravity feed it next time i have some spare time. i have the electrosport flowchart somewhere, but what/where is the stator and how do i test it?
