bbolesaz Posted January 20, 2017 Share Posted January 20, 2017 Full data sheet on the G8HE here: http://www.omron.com/ecb/products/pdf/en-g8he.pdf That data sheet looks more like it. Basically same specs at the G8HN. I guess Digi-Key has an old or bad datasheet. BTW, the G8HN averages about $15 on ebay, so the G8HE is quite cheaper from Digi-Key.

docc Posted January 20, 2017 Author Share Posted January 20, 2017 Thanks for finding the product on DigiKey. Kiwi_Roy put us onto them years ago and they are great to deal with. I try to avoid posting Amazon or ebay seller links because they are so volatile and dry up/ go dead. DigiKey is a reliable supplier with no minimum order. Thanks, again, bbolesaz!

MartyNZ Posted January 21, 2017 Share Posted January 21, 2017 Please do this simple *easy livin' test* (continuity from Fuse5 to Relay#1) on your V11 and post results , and let's see if we can nail down where the wiring may be different or may have changed. No continuity on my bike. It has 3 in the VIN number, but looks like an 02 model. 1 Link to comment Share on other sites More sharing options...
docc Posted January 26, 2017 Author Share Posted January 26, 2017 brlawson has confirmed that his 2000 Sport ain't livin' easy neither At least, that's the way Alabamans spake t' Tennesseans . . .

docc Posted January 26, 2017 Author Share Posted January 26, 2017 *Best* relay for the V11 has been the High-Current OMRON G8HE-1C7T-R-DC12 , but out of production and hard to source.

Anyone with a 2001 willing to test Fuse5 -> Relay#1? Thats the way my 2001 is wired. Notice how it bypasses the ignition switch, this bike will never suffer from Startus Interuptus. A couple of years later they used Fuse 5 for the headlight and used Fuse 4 through the ignition switch to try and feed the start relay, I'm guessing this improved on charging at the expense of reliable starting. Sorry about the sketch, you can check it from Carl's http://www.thisoldtractor.com/guzzi007/schematics/2004_V11_Sport_Catalytic.gif 1 Link to comment Share on other sites More sharing options...
gstallons Posted January 28, 2017 Share Posted January 28, 2017 And that OMRON High Current relay will be the Digi-Key part # Z5645-ND . http://www.digikey.com/product-detail/en/omron-electronics-inc-emc-div/G8HE-1C7T-R-DC12/Z5645-ND/2755412 Link to comment Share on other sites More sharing options...

I ask because I recently installed the latter in both my LM's. For continuous current, the G8HN are fine in all positions EXCEPT #5. G8HN OMRON and the latest Panasonc are rated 10 amps NC/ 20 amps NC for continuous current. *Probably* fine in Positions #1-4. G8HE (high current) OMRON is rated 20 amps NC/ 35 amps NO for continuous current. All V11 should use the high current relay in Position #5. And in Position #1 on 1999-2001 V11 that *fail* the "Livin' Easy Test": (continuity from Fuse 5 to Relay #1). G8HE OMRON is rated 20 amps NC/ 35 amps NO for continuous current (about double the G8HN). Link to comment Share on other sites More sharing options...

I ask because I recently installed the latter in both my LM's. I would heed what Docc says here as the No.5 on the 2002 LM failed now and again to activate the fuel pump. You would hear the Relay click but no go. So until the more heavy duty relay shows up I switched the No.4 and No.5 around and for now all is good. But I am not going on any trips lol. Just near my house and trailer use. Link to comment Share on other sites More sharing options...

docc Posted January 31, 2017 Author Share Posted January 31, 2017 For the record, I did not make this stuff up myself. This is a compendium of years of observations, measurements, failures, and ongoing input. I learned all this from you guys (much from Kiwi_Roy!), 100,000 miles, and twelve Spine Raids. I'm on my sixth generation relay set. But, it ain't over yet! : Last time I measured the temperature of OMRON G8HN Relay#5, it was ~147ºF. If it is not materially improved with this double rated G8HE OMRON, I will be surprised (and, perhaps, a little disappointed). At which point, all of the stops will be pulled out . . . 2 Link to comment Share on other sites More sharing options...
gstallons Posted January 31, 2017 Share Posted January 31, 2017 Is this a photo-shop relay ? Link to comment Share on other sites More sharing options...
docc Posted January 31, 2017 Author Share Posted January 31, 2017 Oh, no-no-no! My clever, young son considered my project and sent me a selection of heat sinks typically used on computer components. Now to try and make some decent science of the IR temperature readings. I've already seen that the heat sinks can extend aft of the #5 Relay without fouling the seat pan.
