The "good" R/Rs have a p/n like FH0xx aa and are newer design MOSFET technology. The "crap" R/Rs have a p/n SH xxxxA. (At least the OEM parts made by Shindengen.) ---- btw highly recommend - www.roadstercycle.com Honda was cheaping out on chargings systems for quite awhile and yours year is from the middle of it. My '98 VFR was part of that too. I rebuilt the whole thing. -- Anyhoo, here's a list to check the system. Start out buy confirming the battery is good. Go through all your connectors for burnt leads, dig deep. Crispy wires? Not good. Your gonna have to fix that! Individual spade connectors dont have enuff cajones to handle the stator to R/R connection. Some guys do a direct solder hookup and others (me) used automotive type Delphi MetriPack connectors that handle high current. Then---Go through this starting point quick list. You will need a multimeter too. Steps: - Recharge battery overnite - then to take it to Autozone, Batteries Plus, or similar to load test. -- Good? Bad? – An iffy battery can fake you out and act like a bad R/R. Buy new if needed. - With good battery fire it up, warm up for a minute or two. These are R/R quick checks--- --- With voltmeter at battery get voltages -- idle volts? 5000 rpm volts? What’s the numbers? Should be in 13ish min idle and in 14s at revs. If in the 12s at idle, try at 1900 rpm. - Check stator - 1. Pull connector apart. Set meter to resistance. Check pin to pin, 3 yellow wires, A to B, B to C, C to A. What’s the numbers? 3 separate readings --Should be less than 1.0 ohms. (Engine off) - 2. Check continuity from each A,B,C pin to ground, -- -should be infinity - nada nothing. no continuity. -- 3 separate checks. (Engine off, again connector is apart) - 3. Crank it back up. Do another pin to pin thing, but set meter on AC volts. idle and 5000 rpms. What's da numbers? Should start 15 -20ish and climb 50ish and more. Again – 3 readings, connector still apart. - Repeat hot. This quick list will catch the obvious stuff, but if you need to dig deeper check this chart. http://www.electrosport.com/media/pdf/fault-finding-diagram.pdf
