After looking at my order confirmation again, I accidentally order the 24v relays🤦 Egg on my face, too. Another good catch, @Speedfrog! The CIT linked in the Best Relay thread answer are the correct 12V CIT. The Pickers Components noted by Speedfrog have slightly better current ratings, especially for the early V11 Sport's #1 Relay/NC contact position: 1 Link to comment Share on other sites More sharing options...
motoguzzikc Posted April 24 Author Share Posted April 24 @docc and everyone else that helped out on this , just wanted to say thanks! My new correct relays came in today and after swapping them out I'm seeing 13.3-13.4v at about 2500 rpm. I won't have a chance to take it for a test ride until tomorrow but can I operate under the assumption for now that with it putting out over 13v while running that the system is charging as it should? I have put 5 extra relays in the tool bag just to be safe. 1 1 Link to comment Share on other sites More sharing options...
docc Posted April 24 Share Posted April 24 Tach totally stable? Rev it up a bit and the voltage comes up? Link to comment Share on other sites More sharing options...

However I will will say that the tach would only do that cycling issue when the bike was going down the road. Not at idle. Tomorrow I'll take the bike out and make sure the tach is better. 1 Link to comment Share on other sites More sharing options...

These are the relays I bought, so affordable I wanted to give them a try. They have been in my bike for a couple thousand miles, no problems at all. In addition, I also bought this relay tester. Works like a charm. 2 Link to comment Share on other sites More sharing options...
motoguzzikc Posted April 24 Author Share Posted April 24 Thanks for the link @LaGrasta @doccjust got back from a half hour test ride. No issue with tach , however at idle it's at 12.6 and at 3k rpm after the ride I am showing in 14.6 v which brings me back to my original assumption of bad reg/rec and that it should be replaced. Any thoughts? Link to comment Share on other sites More sharing options...

Any thoughts? The voltage at idle is a little low in my opinion, but that it goes up to 14.6 volts at 3k rpm says the reg/rectifier is doing its job. The low voltage at idle would more likely be down to a lack of voltage output in the alternator. That could be from a low idle or a reflection of the generally weak design of the Italian charging system. It could also be an issue with the battery itself, either being weak or needing some conditioning, causing the battery to not be able to hold the charge it was getting when the rpms were up. But honestly, I would not worry about it as long as it is working that well. 3 Link to comment Share on other sites More sharing options...
motoguzzikc Posted April 24 Author Share Posted April 24 Sounds good to me the. I was under the impression that 14.6v was too high. The battery is only a few weeks old with less than 100 miles on it. I'll take the win and just ride then. I really appreciate all the help on this! Link to comment Share on other sites More sharing options...
LaGrasta Posted April 24 Share Posted April 24 I agree with @docc, let it be. I don't recall what battery you have, but some have circuits to prevent overcharging. My advice, ride regular. This alone helps many potential issues; including our mental state. 1 Link to comment Share on other sites More sharing options...
motoguzzikc Posted April 24 Author Share Posted April 24 @LaGrasta thanks ! I picked up a new Odesy from Harper's so I was also playing it safe for the battery's sake as it was not inexpensive. Riding looks bad here after today but great next week so I'll put some miles on it! 1 Link to comment Share on other sites More sharing options...
docc Posted April 24 Share Posted April 24 The low idle voltage could be down to a low idle. These tachs can read 300-500 rpm high. No big deal, perhaps, at cruising speeds, but setting your idle at 1,000 rpm with the tach when that is really 500-700 rpm is not good. Use Guzzidiag to confirm the actual idle and the "Decent Tune-up" for the idle procedure. Good to keep an eye on the charging voltage. The Odyssey is not to exceed 15.0 volts. 1 Link to comment Share on other sites More sharing options...

Any thoughts? The max voltage is too high. Is this figure with the headlights on or off? 14.6 volts will eventually cook the battery. As docc pointed out 12.6 is a little low at idle but then it depends on what the true idle actually is. Phil 2 Link to comment Share on other sites More sharing options...
GuzziMoto Posted Thursday at 01:33 PM Share Posted Thursday at 01:33 PM The odyssey battery is fine up to 15 volts according to the people that make it. Here in the states you can't turn the headlight off. And the V11 Sport stock R/R uses the headlight circuit for its battery voltage reference as I recall. If you turn the headlight off it would stop charging. 1 Link to comment Share on other sites More sharing options...
motoguzzikc Posted Thursday at 02:17 PM Author Share Posted Thursday at 02:17 PM @GuzziMotothanks for the post ok the allotted volts for the battery. This helps out my mind at ease. I see a lot of posts on here about the guzzidiag tool, can anyone link the most useful? I want to know where to download and what hardware I will need. During my boring day job I'm a Software QA so I feel more then confident working with the tool as opposed to my extreme basic understanding of power flow on this bike lol. Thanks in advance for any help Link to comment Share on other sites More sharing options...
