Greybeard Posted April 27, 2010 Share Posted April 27, 2010 Would it be alright to eliminate the multiple ground wires going directly to the battery by tracing them back to their origin and grounding them to the frame there ? (Making certain, of course, that continuity is maintained) Drill & tap some holes and be done I figure. Oh, also...the R4 & R5 relays...ECU and Injection is it? Anyway they're smaller than the other 3. Do they have different values or can I order all 5 of the better relays? Link to comment Share on other sites More sharing options...
gstallons Posted April 27, 2010 Share Posted April 27, 2010 You could do that. You have to run a ground wire from the battery to the point you are using to ground to. p.s. Use shakeproof washers to establish GOOD grounds. Link to comment Share on other sites More sharing options...
docc Posted April 28, 2010 Share Posted April 28, 2010 A couple systems that really benefit from frame grounds are the headlights and the horns. These are also the systems that benefit from a separate fused power feed to auxiliary relays . . . Moving the terminal stack to a 'bus' or junction block is also good electron medicine. As is strapping a ground wire from frame to block on the motor's front. Veglia gauges benefit from anchoring the instrument light bases to insure grounding. There is no benefit to using smaller relays in any of the five positions. Relay 5 runs the fuel pump (as well as the injectors and coils) constantly and, you may notice, it stays a bit warm. After using five generations of relays (2 Siemens, Bosch, GEI, and OMRON), I have no doubt that the OMRON are the best available. We can thank John Mickowski (RYLAND3210) for the extensive work on this. If you have Bosch or GEI, they are, frankly, okay; just not best. Link to comment Share on other sites More sharing options...

Here are the relays Order all 5 pin, they are interchangeable http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=Z2247-ND Digikey also have the little switches that go on the Brake / clutch levers Regards Roy Link to comment Share on other sites More sharing options...
Nick Posted March 31, 2017 Share Posted March 31, 2017 A couple systems that really benefit from frame grounds are the headlights and the horns. These are also the systems that benefit from a separate fused power feed to auxiliary relays . . . I just added two relays to my EV's headlights and they are now visibly brighter. Would my '04 V11 benefit from the same setup or does it have a dedicated headlight relay already? TIA Link to comment Share on other sites More sharing options...

Lots of owners have reported brighter headlamps with fused power to a dedicated relay, grounding headlights back to the frame or block. brlawson just got the components and materials from EasternBeaver to do this. http://www.v11lemans.com/forums/index.php?showtopic=19803&p=218190 I decided to use separate relays and grounds for the hi and lo beams, but I'm a certifiable nut case. Of course, everyone here knows that already . . . . 1 Link to comment Share on other sites More sharing options...
