  1. Okay so that answered a ton (at least two) of the questions that I have been unable to get answers for... 1 - does this system have a field wire? The voltage reg takes an input/output from the stator and I got conflicting info about this, but noticed that the three phase wires seem to relate to the charging table that Jeepurz provided (in my Clymer manual as well) 2 - What to do with the three wires? I saw in the orig cb500t wire diagram that the white wire and the yellow wire get tied to each other (prob after the highbeam switch) At first I was going to do the same before the rectifier, but then decided I was going to build a three phase full wave rectifier (got the parts laying around believe it or not) So perhaps a either a BWD Voltage Reg with no field wire or the CBR600 R/R. Thanks, this helps.
  2. Found this thread http://www.thechopperunderground.com/forum/index.php?showtopic=30623 and also found that the voltage regulator part number at advance is a R292 and is called a BWD Voltage Regulator and sells for $25. I think I am going to pic this up and give it a try. I'll post back on Thursday with my results. Thanks again.
  3. sounds great, thanks so much. Did not realize there was an Electrical T-Shoot section. Truly appreciated. - Eric
  4. Hey Jeepurz, Thanks and yea, I got the same specs on the amperage from my online manual. I suppose, I could try a ampere load test (place meter between the battery and stator feed [after the reg]) but the issue is that I cannot get the voltage regulator to exceed 7.8 volts. Even on a test bench, both voltage reg show a 7.8 volt output. Is it possible that both 36 year old regulators failed the SAME way?!?!? not sure what to do as I do not want to continue to purchase new components as a grabbing at straws approach. Thanks so much for the help. Any ideas on a good 12 voltage reg that I could put in its place? How about putting in a CBR600 rect/reg single circuit? Any thoughts? - Eric
  5. Hey Jeepurz, not to hound, but any word? Thanks man.
  6. Been there, love it! Now for the fun stuff :-) Well done man.
  7. I know, I know but I need someone to validate what I am seeing on their functioning CB450 or CB500t... I have been reading some conflicting information with regard to stator resistance. I know this is not the BEST test but it is the first step. From Pink to Yellow = 1.5 Ohm From White to Pink = 1.5 Ohm From White to Yellow = 1.5 Ohm From White to Ground (Assuming the white is the field coil) 2.2 M-Ohm (this would be bad so I am not sure about this one) ====== Clymer manual says "The rotor is permanently magnetized and cannot be tested except by replacing with a known good one" I thought that one of the wires was a field coil wire which means the voltage regulator sends a voltage to this wire if the battery voltage gets too low thus increasing the output voltage of the stator (and current). I am banging my head here and could really use someone with a functioning CB450 or CB500t to take some measurements and let me know what they find. Much appreciated.
  8. I need more pics of this bike. This is very impressive, keep it up.
  9. It is a 1975 CB500t. I have been told that the stators rarely go bad on these old Hondas. That being said I have no idea what the output voltages ares supposed to be before the regulator. The manual only states (unless I missed it) that the charging for the 500t starts at 2800 rpm with ~5 A. Thanks again.
  10. Yes I agree that the stator produces VAC however once both AC leads are connected to the Rectifier the output of the rectifier is direct VAC to VDC translation i.e 120 VAC into a rectifier equals a 120 VDC output (actually there is a .7 VDC drop for the bi-polar junction of each diode but who is counting anyway)
  11. Gents (and ladies), I noticed that my original rectifier and regulator were not charging the battery so I bought a new rectifier (start simple). I hooked it up and measured the output directly after the rectifier (no regulator) and found some interesting reading and do not think these readings are normal. Please help me understand... At idle (no tach) I was around 30-40 VDC and at a few thousand (I am guessing) I saw it climb to as high as 120 VDC. I know the regulator will limit the output to ~12.4-14 VDC but I must say that I was not expecting the output of the rectifier to be that high. Thoughts? Thanks, - Eric
  12. I would think that it would be smarter to stretch the rubber 1/4 of a millimeter than than trying to pinch and seal and extra 2 millimeters. I mean, 1/4 of a millimeter is pretty tiny. Let me know what changes you make to the jets if any and how it runs. Good luck.
  13. Just saw this in "The Horse". Damn well done!
  14. Nice!
  15. I know this Bike! Sup WtrDog!?!?!?
