Yes, I'm not always sure the details are correct on those diagrams. But there is no difference as far as the start relay is concerned.

Mike, that's the one for the carb model, but the start relay wiring is the same. I linked to the injection diagram earlier.
 
Yes, so as we said, relay 42 must be removed and a bridge put in from 30 to 87.

I can see from this which is the front end etc.
An achievement for me.
Are all wiring diagrams like this?

Yeah I see... wiring diagram here.....

http://www.thisoldtractor.com/guzzi007/schematics/1994_California_1100.gif


35 is starter relay

42 is the headlamp off relay.

But if pin 30 of 35 (blue/black wire?) is made permanently live, current is contantly draining down relay 42.

Hmmm, I will have to study the instructions in the thread. Electrics are not really my forte, as you have probably gathered! Fortunately I always switch lights off before I kill the engine.

Yes, I found that out the hard way, having done the mod, the light relay coil is powered all the time, regardless of the ignition. One dead battery later.....
All that relay does is cut the headlight when you press the start button to reduce the load on the battery. Trick is to switch the light on after starting.

Brian. I misunderstood. I thought you meant do the lights come on with the ignition, then go off when the starter is cranked. I went out to check and if the lights are left on with the ignition off, the headlight comes on when the ignition is switched on, then goes off when the starter is cranked. As it happened it started right up, responding immediately to the starter button.....

As I understand it, if I do the starter relay mod, then I must remove the headlight relay and bridge across?

Put your finger on each relay in turn and press the start button. You will feel the relay operating.
 
Is this the diagram you are looking at?
 
According to that your lights should go out when you press the start button if they have been switched on. There is a headlight relay (42) to do this, which is powered from the start relay (35). Look at the wire colours on the start relay (yes I know it's called the starter solenoid which is incorrect).

Looks like I can attach a picture, by not using the 'quick reply' box.  A bit grainy, but the 6 relays can be seen ok.

John. Yes, cleaning the earths are on my to-do list. Thanks for the tip about the seat. I will take the necessary precaution!

Brian. I have now got up to page 5 on the 'Click no crank' thread; certainly seems to be a issue MG should have addressed long ago. My headlight does not come on when the ignition is switched on, fortunately by the sound of it. I will have a look at carrying out the mod, but it would help if I could identify the position of the starter relay. I cannot seem to find that info in the wiring diagram, unlike the fuses which are itemised on the inside of the r/h cover. I was going to attach a photo of the relay/fuse  block in the hope that someone could say which is which, but I don't seem to be able to do that.

The starter button issue is a known problem. Go to the FAQ section and look at the "Click no crank" topic.
 
Does your model have the headlight come on when the ignition is switched on, then the headlight goes out when you press the start button? If so read carefully the bit about this.
 
The original running problem was certainly a dirty connection somewhere. Worth using that spray on every electrical connection and switch you can find, including the ignition switch.

Hi Ian. Was in a similar situation this time last year with a 1995 1100i.Just in case the gremlins come back, or as an enhancement even if they don't, locate all electrical grounds that you can find.Clean/sand them and refit.I used petroleum jelly to seal the connections.The main source of my woes was traced to a defective coil which malfunctioned once heat was generated.The advice I got here greatly helped.Also,if yours has the two piece seat, water can soak down into the ecu and and relays under the side panel.I'm told that stiff plastic over the ecu to divert water can help.Good luck!
