Another R/R question...

Okay guess its' my turn. :censored: :rant: After twenty five years of owning VFRs, of just about all the models less the 6th I've never had a R/R problem till this weekend, in fact I'm still not sure it's not a battery, as it charges just fine in the morning cold, puts out 14.7v at 3500rpms but once warmed up no charge even at 5k rpms 12.7v so was looking around for info, and whats ya know, I found it. Thanks guys. still need to do a load test on the battery, then I should know for sure. Speaking of batteries, any know if Optima makes em for motorcycles? damn nice battery if you ask me.

 

R/R problem

I have the same problem as hater81 i've got a 94 750FSo while riding at night my bike lights started to dim and then dies ouch battery is dead but damn my frame was very hot. It was a warm night in San Diego last week
I'm not showing no difference in volts on my Battery it reads 12.18volts even with the bike on and at 5000 rpms. I've read most of the posts and adding fans to rewiring can get to be no fun at all. Help i cant keep buying R/R this is my 2nd one was aftermarket, 1st one was factory.

 

Have any of you tried www.servicehonda.com my 5th gen had r/r problem
and got OEM upgraded part much BEEFIER than original part for $113.00
with warranty and its a NEW honda part.

 

Hmm you wouldn't happen to have a part number? as I just got off the phone with them and they say they don't see that as being something they carry, plus even thou it's still less, the one they do show is the stock replacement which goes for $162, list of $212

 

Sorry to hear it was your turn RVFR. Hey, Rick's Motorsports and Electrosports have good quality aftermarket RR"s.

Just an FYI

Thanks, Bubba guess my luck finally ran out. Yes, going to give Electro a call in the morning and blue label that thing. So whats this Voltmeter do dad I keep hearing about? can't find the green one I see on here, thou some are close anyone ever use a red led meter that spells out the voltage like these do.

You can get the LED one from denniskirk.com They run just about 30 bucks plus shipping.

 

OK, so to anyone who still checks this thread out, here is how the never ending saga continues..... Got my 3rd new R/R from electrosport. Got tired of taking chances and ordered a new stator from them as well. Installed the new stator and R/R, ran new wiring from the stator to the R/R and wires directly from the R/R to the battery. Installed my new LED voltage gauge and prepared myself to hit start on the grip. Hold my breath and push.....not charging. The only way I can get the thing to charge is if I disconnect both headlights and dont hit the brakes. Even then its barely 14 volts if that. Thought maybe its the battery. Load test the battery, test good, 200 CCA and 12.3 volts. Check to see what the new stator puts out, only about 45 volts AC. Great, the new "heavy duty" stator puts out about 30 volts less than the original stock one. OK, so now I decide I am going to contact electrosport and see what they say. They tell me that the new one is defintaly bogus and to return it for a credit and reinstall the old one. So, I follow through and do so. The old stator puts out about 75 volts AC at 3,800 RPM. Still not charging though, and the wiring is getting very hot. The connectors start smoking. Still with me???? Realizing that the new wiring is doing nothing for me, I put the old harness back into action. Solder all connections and shrink tube. Re-ohm all wires and check for shorts. No shorts between the field wires from the stator or shorts to ground. The ground wire at the R/R to ground has good continuity and no high resistance. The output wire from the R/R to the battery is good with no shorts or high resistance. Last chance to bail out now so keep that browser back button close at hand.....So now in conclusion.... all wiring all wiring checks OK, no shorts, no high resistance. Put all wiring back to normal. Load test the battery and checks OK. Check stator output, checks OK at 75 volts AC. I have what I assuming to be a new proper R/R installed. And still the bike does not charge. On the last test ride I went out on I believe whatever was left of the R/R and charging system is finally gone because it won't even hit good system voltage of 13-14 volts even at HIGH RPM's with no lights on. At this point I am totally frustrated and disgusted. I am in the process of trying to get my money back for all the regulators and the stator and put that money to buying a new Honda regulator. Any thoughts or good luck incantations ANYONE knows would be greatly appreciated OR anyone wanna buy a decent VFR 750 with a bogus charging system?????

 

O man whew!! I ordered one of those RRs from them too, lets hope it works. Mine charges only when cold, once warm/hot no charge. 38k on the stock RR Battery checks out. I'll let you folks know how mine turns out. What a bummer Hater, I'd still try and figure it out, way to nice a bike to discard. but do understand your frustration.

 

If I remember right the part number was the same as original but honda
has just upgraded the part. going on 4 months now so far so good.
Good luck.

 

Hater,
I am still with you and am hoping that I have better luck than you are with this electrosport R/R. Mine was electrosport and it went bad already. Just bought it on the 24th and installed after it got here. It was good when installed but now is overcharging. I had 18-19v @ 5000 rpm. I bought mine off of ebay from a seller named rmstator out of Canada. I called them up and they said send it back and we will replace it. No questions asked. If nothing else, this company is great to work with. Very nice and no BS.

I am looking at one on ebay that says it is a heavy duty R/R and claims that the others aren't really designed for a bigger (750-800) bike. I want to see what the new R/R does but one thing i know for sure is I am going to beef up the wiring and try to avoid this trouble. Also, I am going to have a spare R/R on hand. Even though they are warrantying the part, I am without a bike while I wait for the part to get back here. If I had a spare now, I could be out riding.

 

Thanks for the continued interest Eleman. It appears that we are in at least a very similar if not the exact same situation. It also makes me at least know that I am not crazy as you too are having problems with the electrosport R/R. I too, am in total agreement with you in regards to the customer service. They sent me a replacement R/R without even recieving my defective one first. That alone is something no other company I have ever dealt with has done. On the other hand, at this point, I'd settle for crappy customer service and a part that just worked as I am also out a motorcycle until I get this straightened out. I believe I saw the same "heavy duty" R/R on ebay, and was also considering picking it up. I think, though, at this point I am going to bite the bullet and purchase the OEM R/R direct from my local Honda dealer and hope that electrosport's customer service continues to impress and refund my money. As more developments occur I will be sure to keep you and the thread posted and hope you will do the same. Good luck!!

 

Ok here's the up date. Recieved the new regulator, Wow, they sent it 1 day at no extra, way cool. Other than the build quality from the out side, small cooling fins and the fact that it has a thick base, so one is not able to use what I believe is the cooling plate with the stock regulator, making it not fit as good as the factory piece, all is good, even just off idle, say 1200rpms she's charging at 14.4 So off I go...

 

Good luck RVFR, it sounds like you got an electrosport as well. Hope it lasts!

 

If there is ANYONE who has a suggestion to Hater81's problem...

PLEAE POST!!!!

I have the SAME problem...all new parts/new wiring...STILL wont Charge.
What is the deal?

-Steve

 

Pearl....the R/R that you replaced, was the replacement made by electrosport?

 

yes. Electro sport R/R
Ricks Electrics Stator.

All new 12ga wiring...still getting battery drain.
Looked liek it evened out around 12.15v
But thats still way too low (without hibeams or anything else like turnsignals)

What gives?

 

That I did.. thanks to you guys, made it easy to find and know whats what. now if only I was able to help you.

 

well the only advice I can give at the moment is I believe the electrosport brand R/R is junk. I believe the internal diodes to either be a poor quality or too small a size for the power requirements of the bike and power of the stator. I am completely at the end of my rope with this situation and the only thing left that I can say must be the problem is the poor quality R/R from electrosport. I am currently in the process of getting at least some if not all of my money refunded and buying a Honda OEM R/R. Lets see how it goes....

 

Hater,
The guy that lives here in town and has alot of experience with VFRs told me he gets his parts from www.servicehonda.com I trust him and am probably going to go there next. Someone posted to this thread that they got one for about $113, Honda part beefed up and had a warranty. I think I am going to check it out.
