I purchase an 84 TRX200 for my wife to learn on about 2 months ago. It was all in one piece except the wiring. The guy I got it from told me it was running last year but it had an electrical problem and he couldn't figure out how to fix it. I believe him because he had an extra wiring harness, regulator, and he said he also replaced the stator.

I started ohming everything out and comparing my measurements to the maintenance manual. Everything looked fine except the CDI so I got a "supposedly" good CDI off Ebay. It measured bad as well so I took a look at the Regulator. It also did not measure what the manual said and neither did my spare regulator. I find it impossible to believe both of my CDI's and regulators are bad.

Has anyone ever had an issue like this. I was about to send the CDI back to the guy but now I don't trust my measurements. Is it possible Honda used a different older multimeter that somehow works a little different than the new digital meters. I know some of the old analog meters were low impedence meters where the new digital meters are high impedence but I can't imagine that would make a difference unless the loading effect of the older meters is needed for proper measurements of the CDI and the Regulator.

Any help would be appreciated, I'd like to get this thing running. I have verified the starter button and ignition switch are working properly and the inhibitor relay is also clicking when I go in and out of reverse. The stator, excitor coil, and pulse generator all ohm out good. The one thing I haven't done is ohm out every wire to make sure I don't have a broken wire but I did try the other wiring harness and that didn't fix it. I can't imagine I have broken wires in both harnesses.

What is the reason for using a different tester on the CDI?
