voltage regulator rectifier concern

Postby littlebeaver » Fri Dec 16, 2011 7:21 pm



I have a concern, the manual on the RR says that the volts should be between 14 and 15 volts at 3k rpm's mine is at 15.23 max should I replace the unit? I don't know if that .23 above is a problem ...I checked it with a multimeter.. thanks for any response

That's a little bit high, yeah. You're going to end up boiling away battery electrolyte with those voltages.

Before you start replacing anything, do three things:

1. Check the ground (green) wires between the rectifier and the battery negative terminal. If there is resistance there, it can make the rectifier think that the voltage is lower than it is, and it will try to boost it to compensate.

2. Check the voltage of the charge output (red) wires at the rectifier compared to the battery positive terminal. If there is a difference, then there is resistance in there somewhere, and it can make the rectifier think that the voltage is lower than it is, and it will try to boost it to compensate.

3. Check the sense (black) wire on the rectifier when the bike is running. It should have the same value as the red wires running to the battery. If it's lower...well, see above.

On #1. I guess I should leave it plugged in and poke the green wire with my red lead and neg. gos to batt. neg., is that right? Well that's what I did and there is resistance on both green wires when its plugged in still, so what do I do, I also tried it unplugged and there is no resistance or the needle didn't move... On #2. volts are the same 12.88 volts same as battery on both red wires..I have not done #3. yet.. my clymer book has a test in it green to the three yellows and then red to yellows and all showed good resistance but it says to reverse the leads and try it again and that's when my little ohm meter needle didnt wanta move :cry: I think I have a defective regulator rectifier... :cry:

Here's what to do. Take a voltmeter, and while the bike is running and engine RPM at around 3500 RPM, measure the voltage between the red wires at the regulator and the battery positive terminal, and then do the same thing between the green wires at the regulator and the battery negative terminal. See what readings you get for that.

Ok I think I'm doing this right...I put the red lead of the volt meter on the postive post of the battery and poked the red wire with the black lead and held it while my wife put it on 35k my reading was neg. 1.04volts the the second red wire was -1.04volts too, then I placed the neg. lead to the neg. battery post and to the green wire at the RR and the reading was -0.13 at 35k on both green wires and around 0.09 at idle...tested the black wire at 35k the volts read 14.28 that almost sound right...I'm now so totally confused...this is what I call winging it... :lol:

Thank Mrs. Littlebeaver for her help. :)

1.04 volts is a pretty significant drop, as there is not much between that red wire and the battery - the only thing in between them is the master (dogbone) fuse. Do you still have your original fuse in there, or have you replaced it?

Let's do the test once again - with the bike at 3500 RPM, measure between:

Red wire at rectifier and each side of the master fuse
Positive post on battery and each side of the master fuse

That will tell us where the voltage drop is occurring.

I'll get back to it tomorrow thank you Wingadmin.... :D So what do you think about the no continuity after I reversed the leads on the cylmer test with it unplugged, doesn't that tell us the unit isn't good... I'm asking because it said that if any of the test failed replace the unit...I'm still gonna test it as you said though... :D

I'm such an idiot...it helps to set the antalog multimeter to zero before you start testing something :oops: I'm such a dumbass, yeh it's showing a resistance of only 3000 on the ohms on green to yellow and red to yellow, I'm gonna replace it.. ... I have a different digital multimeter I set it to ohms and put it on 20k it doesn't read but the number 1 on it...Am I doing something wrong? when I put the leads together it reads 000 just fine? But I am not getting a reading at the RR plug wires...I'm still going to test it as you said and get back to you...Ok we just got back in from doing the last test you asked for...Red to both sides of the fuse show -28 and post from battery to both sides of fuse is-3...

Ok I may have found the cause of the red wire drop, that plastic plug, one of the spades in it was melted to the case, I removed the plug and soldered the wires direct.. Now I have a Ford solenoid on the bike works great, I also installed a 30amp fuse, it has one wire going to postive on the solenoid it's shared with the postive main wire to the battery on one of the two large posts on the solenoid, now on the other side of the fuse line I put the Red wire [ignition] and the red and white wire [RR] together put it on that line coming out of the main fuse. :shock: ..The green and red wire go to ground at the base plate of the solenoid :shock: , the yellow and red go to one of the smaller post for the starter button :shock: ...Now I taped up the base of the solenoid really well so it didn't ground out to the frame in it's cave :shock: , I even put a zip lock bag over it to be safe. :shock: .It seems to have worked well for some time now :D ..I would bet that damage accured due to that bad plug connection. :shock: and riding all over the country side like I know what I'm doing :lol:... Not...

positive, positive, positive, positive, positive, positive, positive, positive, positive, there I spelled it right.. :lol: :ugeek: My wife didn't complain once helping me, she's getting pretty good on the throttle there...I better watch it she's gonna wanna bike now.. Thank goodness for voltmeters man I'm glad I caught this..I'd be somewhere in lower kansas or something when the bike shuts down... :o Damage to the rectifier could have also happened a long time ago because those pesty three yellow wires were burnt too..I never bought a volt meter and didn't have one until just lately duh... :cry: such foolishness I swear.. could of, should of, would of..... :lol:

Multimeters are cheap. I have a cheap one in the "extra tools that Honda doesn't supply" tool kit in my bike, along with a spool of wire, electrical tape, solder, and a butane torch. Probably won't need it on the 1500, but it was cheap insurance on the 1100. I've never yet had to use any of it on my bike, but I did end up using it to fix the bike of a young girl I found stranded at the side of the highway a year or so ago.

Wingadmin. can you explain to me what these readings are telling you and what they should be...And the discription of my wiring, does that sound correct to you...??? the test from the battery to both sides of the fuse, is that about right? I'm so confused as I never learned much about this stuff in detail..

I gotta say guys, the one thing you gotta go get yourself right away is a good digital multimeter, the antalog one is good for ohm testing but that multimeter has the volts on it and your really need that, I'm not ashamed to say I'm not an expert at this electrical stuff as I'm still trying to learn as I go but I have learned a lot here lately, I'm just glad I didn't blow my ass up...I totally get the concept of tracing down the readings now in that red & white line..by testing at each side of the fuse...is that reading correct though because if it's not that tells me that its the connection at the solenoid or the positive battery terminal..But if that were the case the bike wouldn't start as it does, it starts with a slight touch of the button.. Wingadmin.... what was wrong with the young girls bike a year ago? Wingadmin, a good how too for Moron's like me :lol: should be on multimeters and how to use the silly thing's...I wish I knew what every symbol meant and why it doesn't work on ohms[digital] ect..And the antalog one too...I pretty much understand most of it, but I know there are guy's that don't know much about the things...And wish they did... :D

That's a really great idea, I'll add that to my to-do list!

So are you still having problems, or was it resolved with the repair of the melted connector?

Thank you Todd, I went out to start the bike today, turned the valve on and pulled the choke like I always do, it cranks up for me everytime all the time never misses a beat, but on this day, as soon as I pushed the choke in it died, started right up again, gave it some gas and it just petered out.. :shock: what...I started it again and it would run with the choke on just fine, the second I pushed it in it would die ...hummmm, Oh snap dude, I looked at the fuel gauge and it was low, perhaps if I switch it to reserve position...Duh... :oops: perfect again...The bike ran fine after that... Merry Christmas Todd up in the Great White North,, and everyone else...Let me know when you get your box...

I need to know from you electrical guy's if my Ford solenoid is wired correctly, so far it's worked perfectly, kill switch and starter button are perfect..The red and green go to the gound base plate on the rear of the solenoid. Now I have the red and the red and white tied in together before the main fuse is this correct or not..??? Here's a lay out of what I have..
I am wondering if I should not have tied the two wires together before the fuse, the red white, and the red. I thought being they both go to pos. it wouldn't matter if they came together before the fuse..Or should it just be one of those wires to go thru the fuse..??? I know the R/W goes to the RR and the Red goes to the Ignition...Which one needs the fuse in the line? I understand things better when I get a visual on something thats why I drew this up...there's one other question I put my stereo direct to the battery on it's on fused line and the trailer light converter to, would that jack with the RR..should I go to the fuse box instead?
