Hi were dose the live feed come from to the relay next to the fuse box that feeds the digiplex control unit
and were is the fuse that protects it ? thanks P:)
-
You'll have to give us a clue ???
Like at least a year or model

<Holding up hand dancing around> I know, I know.. ;D The sidestand relay. (even if it doesn't have a sidestand switch) ;D Power to the sidestand relay is triggered by the kill switch. Power to the kill switch comes from the ignition switch.

Sorry its a 1993 California
the kill switch operates the relay but were dose the live come from
that the relay connects ?
after the side stand relay there is another relay

I think this is the schematic

As Chuck said " Power to the sidestand relay is triggered by the kill switch. Power to the kill switch comes from the ignition switch."
In typical Guzzi fashion there is no fuse protecting the ignition switch, it's designed to catch fire and burn ;D
Relay
35 is Start Relay
40 is Horn Relay
41 is Stand Relay
42 is Headlight Relay
Do you have a problem?

If it's the same as the 93 Strada, no reason to think it isn't.. the "another" relay powers the coils *and* Digiplex. That's the one up by the fuses. It's not clear on the wiring diagram. I worked with Carl on this, but we never did get it completely right. Apparently, I couldn't make him understand. <shrug> There is a whole thread on this somewhere here. Search for Strada and Digiplex..

i am getting my head around this now but what i can not work out
and is not on the wiring diagram is were the red wire that goes to
30 on the digiplex relay comes from
and is there a fuse to protect it ?

I don't know the Cali EV but as a retired electrical engineer I CAN at least read Roy's (or Carl's) wiring diagram. The power feed goes into pin 30 on relay #41, and bridges over to pin 86 to power the coil. (The other end of the coil is grounded through the side stand switch to activate the relay. Note that when this relay is activated, it interrupts power. Convention is to show a relay in its non-energized state.) The wire (shown as white on the diagram) goes through a multipin connector (changing color to blue stripe) and through the kill switch where it changes back to white and goes through another pin on the same connector over to #17, which is labeled as "start switch" but I believe it's actually the ignition switch. If you look at the rotating connector inside the circle, it seems to be shown in "off" position in the drawing with the wires, since nothing is connected to anything else. The middle drawing shows "on" with all the contacts made. The far left picture shows "park" with connection made only to the tail light. (BTW, the thing in the upper left corner labeled #4 should actually be labeled #14, the 4-way flasher switch.)
Power comes into the ignition switch on the upper right red wire, labeled #30. If you trace that red wire back through another multipin connector it eventually winds up at #36, the starter motor. That's the copper bolt where the big battery cable attaches, also used as a junction point for power feed to the rest of the bike (to avoid having too many extra wires on the battery positive terminal.) As others have noted, there is no fuse anywhere in this path, it runs straight between the battery and the ignition switch.
Hope this helps clear things up some.

You seem concerned about the circuit being fused. You can add a fuse if you want to. Just remember it's there. :)

Sure. Put a 30 amp fuse on there, and Bob's yer uncle.. ;D

I have added an in-line main fuse (30 or 40 Amps) to all my bikes right at the battery.
On the EV I added 3 6mm bolts under the RH side cover mounted on an insulating board.
+ 12 from the battery through the main fuse, from here goes the feed to switch and battery tender connector
+ 12 switched by the ignition, from here goes the switched fuses, heated accessories etc
Battery Negative
This leaves me with just two wires on each battery post and none piggybacked at the solenoid
The main fuse is a convenient way to remove power or disable the bike.
Adding the fuse had an additional benefit, I was able to tap into the nice fat feed wire to the switch and power up a pair of headlight relays, they are protected by the main fuse.
-
I have done that as well, using a resettable marine breaker for the main fuse. I attached it to the ground side of the battery and all returning juice flows through it. When I want to disconnct the battery I just push the button on the breaker and it opens the main ground circuit.
My trike has the main positive wire from the battery going through a 150a relay, switched to the ignition. It cuts out the (+) side except for the starter and battery charger plug.

Thanks to every one for your help misfire sorted fuse to be fitted shortly

So what did it take to sort the misfire? We need to keep the knowledge base updated..
-
put new ignition switch on first did not do it
took side stand relay out of circuit wired direct to digiplex relay did not do it
tightened up and cleaned contacts in digiplex relay and cleaned relay contacts and whoo hoo
now running like a Swiss watch

I had the same thing happen on my SPIII. On my SPIII with a Digiplex ignition, it would occasionally quite and then restart, a most dangerous situation. In an effort to fix it, I replaced the ignition relay with a SPDT relay (5 pin). With the new relay, it just wouldn't run. Upon checking, I found that the 5 pin relay is in fact a SPST relay with the center pin just another connection to the 87 pin. So what you have is two 87 pins connected (both are designated as 87, not one 87 and one 87A). On the SPIII, the center pin needs the connection to the outer pin in order for the ignition to work. I removed the connectors from the collector and tighten them up before reinstalling. Everything is now fine.

i did exactly the same as u described and found out the relay was a double throw sounds
like we have had the same problem
-
I'm a little curious about the "Digiplex Relay"
Is it a special one that other ignitions don't have?
Can you point it out on a drawing.

It's not on the drawing that Carl made. I couldn't make him understand that the Digiplex relay is triggered by the sidestand relay. He shows the sidestand relay as the Digiplex/coil power relay. Yes, it is a double pole. Those relays are expensive, around 40 bux from memory.
