[cangeceiro]

im looking at purchasing a 75 cb750k8 from a friend of mine, he has had the bike for about 2 years and i know it always ran well for him. at the end of the riding season last year he said he was riding home and the headlight went out. now we pulled it out of the garage and it wont start. im not getting spark at the plug, or lights. for lack of the proper tools i spent a few hours testing the electronics with a light bulb just to make sure everything that should be getting voltage was getting voltage. I successfully had power at the lead that powers the coils, into the power switch in the handle bars, going into the voltage regulator, the instrument cluster, and 1 of 3 fuses. while tracing back wires i noticed everything that was being problematic all in directly or inderectly ran back to the voltage rectifier.

so my question is this...could it be the rectifier and/or regulator. would this be the behaviour i would expect if one of those were bad. and how would i go about testing those? i do have a multimeter for testing. i just didnt have it available last chance i had to work on it.
