testing honda r/r

[davegs850]

I purchased a honda r/r 232 12 trying to test the diodes first time with a meter be gentle please. When I set the meter to the diode setting i get a reading of 1 before i hook it to anything and none of the readings change when i hook the positve to red and then check each of the three yellows What am i doing wrong??

GO to BaseCliff's site The Suzuki & Honda reg are checked the same way There is a very detailed post..

I am trying tofollow bass cliffs sight and also the stator papers very new to a meter I dont know if i should have a reading of one when i set it to diode and still cant figure what i am doing wrong

[davegs850]

update when I hook the black lead to the red r/r wire and the red to each of the yellows I get readings of 589 589 and 604

A "1" on your meter in diode test function means very high resistance in that direction. Reversing the leads gives you the forward voltage drop, like 588 ( actually .588 volt). now do everything else Basscliff spelled out!

Absolutely nothing.

Sounds good, now you are half-way there.

Move your black meter lead to the R/R ground wire (probably black), you should get your "1" reading on the meter. Switch leads, with the red lead on the R/R ground wire and the black lead on the yellows, you should get some readings.

Note that this only tests the R/, but not the /R. Yep, this only tests the Rectifier, but not the Regulator. That has to be done with the engine running.

thanks steve i went through the rest of the diode tests and everything seemed ok. So I hooked up the honda r/r to the bike I hooked the red and green wires directly to the battery the positive through a 15 amp fuse. Now I start checking again. 13.5 at Idle 16.5 At 5000rpm. Next step check for bad connections. I think I am ok. SSo does this mean the regulator function is bad. Is there another test I can do with the bike running I Really appreciate everyones help

This is a SH-232 - where did you hook up the black sense wire to?

P.S. don't run it until you sort out that high voltage- at 5k , max voltage should be about 14.5 volts.

[davegs850]

hooked the sense to brown wire going to taillight also can i run it if i disconnect from stator

You must have a large voltage drop going to taillight (switch?). use a jumper wire to wire R/R sense wire direct to battery positive and see what you get now at 5k.

tom I just did as you suggest and I get 14.32 at 5000 so should i just hook the sense to the positive and do i just do this with another ring connector

Yes, you can secure the sense wire to battery positive. On this model R/R, I measured the sense wire current draw at .0004 amp with bike off - a negligible amount; bike could sit idle for a month with no problems. You should plan to investigate why you have a large drop to wherever you previously connected the sense wire.

tom 14.32 at 5000 rpm 13.32 at idle does this mean i need to hook the sense wire to the positive and do i do it with another ring connector also is the idle figuretoo high?

[tom203]

Be happy! getting 13.3 at idle is marvelous especially if headlight is on! Just make sure you connect the sense wire securely to battery positive- a ring connector is fine.
