Relay redux


Recommended Posts

Relays.

How many here on the forum has done the upgrade with an extra relay for starting, 03 and newer bikes ?  What kind of relays were used ?     Did I miss this somewhere ?

Cheers Tom.

Good question, @Tomchri.

Looking to split the relay content to a thread of its own. Too important to bury.

Gathered replies from an unrelated topic to consolidate here with references to other important relay threads.

The inquiry began when @bridge got his clutch working and posted this question on April 13, 2021:

"Now, my high beam, horn, and tachometer don’t work. The fuses are all OK. It’s a mechanical tach, correct? Where should I start to troubleshoot the high beam and horn?"

Here is one of the more complete threads on this 2002 and on V11 wiring issue. Click the the lower title and it takes you to @Chuck's original post, click the top title to go directly to a detailed post by @gstallons. Several other posters in that thread with detailed information including @Kiwi_Roy and @vuzzi:

Finished the wiring the same way as GStallons did,  after reading a LOT. Just havent put a relay to the wiring yet. Gene just used a relay hanging around.  Just me, why not use the best relay available, right ?    Woud it be enough adding another Omron ?  Relay 1 and 2 are talking together, so the extra relay has to be better ?   Obvious didn't read enough first time, feeding power to 30pin start relay,,, oh well, lights and oillight on.  That fused powercable just went in the Greenie, perfect.     

Yes I like reliability from the gal :rasta:   IPA time.

Cheers Tom.

One advantage to adding a "standard"  automotive relay as @gstallons did,  is you are not restricted to the small size of the Micro ISO Relay as in our fuse block. So, you can easily source a 35-45 amp NO contact relay and find a place for it under the seat. Make sure the rating is for "contituous current" not just inrush.

Well , it worked and didn't catch fire .... That's good enough for me !

If you want to know what amperage this starter solenoid is drawing ; purchase a mechanical ammeter / amp gauge and wire it into the wiring terminal at the end of the harness that plugs onto the solenoid . Then go through the ammeter and back into the spade at the solenoid . Crank the engine and see what A it uses to operate the starter . It may go to max A in the beginning . Just see how much it takes to operate the starter . This will be the amperage required to operate the solenoid . 

 Make your decisions then . I was too lazy to do all this .

No fire here either, just smiles. Put in a 70amp relay, why not overdue it.

There is some seriously intentional "owner involvement" in that electrical system! Look at that stand of U.S.A.-made High Current OMRON!

And a sturdy ECU case ground . . .  such nice grooms, loops, and ties. :nerd::luigi::bier:
