Yep, arcing builds up crud at the contact points, this creates extra resistance which can either
A. stops enough current getting through (click-no-start)
B. adds excessive heat (Ohms law, I x R = V, V x I = Watts), so might end up spot-welded together!
Relays do have a finite life, as datasheets usually specify as ‘X’ number of operations, conditionally variable by whatever the load is.
Appendix ~ what you could do (just remembered) is temporarily try one of the other relays in its place, provided it’s the same pin connections etc.
HTH
That makes sense, I did wonder.
So, it looks like I might have at least part of the FI version loom
However, Carl Allinsons wiring diag for the injecte version shows 6. Does the 6th one normally live with the other 5 or somewher else on the bike?tris2012-09-23 15:12:54
I asked the Bretherin on Wild Guzzi the question and it appears that the Digiplex has its own relay controled supply.
