My cb750 scrambler build. Restart

[mike the bike]

That's what I said originally,  those 2 wires go to the coil in the middle of the alternator.   When the battery is low, a current is made to flow in that coil which then produces a magnetic field which makes the alternator churn out some more leccy (yellow wires).  Because it's the back - and - fore type leccy, the rectititifier turns it into one way type leccy that the battery likes.

Sorry about all the technical jargon.

Ohh. Is that the flow field part of the stator?

Thanks Mike, I'll go in with a bit more confidence now.

I like that explanation Mike.

Cheers me up in a gap from buying, fetching and planning stuff for Christmas.

I don't think I'm in any danger of completing the list I've been given, there comes a point when you have to cut and run to the alcohol. I justify that as categorising it officially under tidying up. Well somebody's got to make a start on it.

Now where did I leave those "eat me" dates?

Venhill custom made cables. Loverly bit of kit.

With original wiring the plug goes in place of the rectifier and the two loose wires go to two out of the three regulator wires, the third one being an earth that is no longer used. The sense wire is an ignition switched live.

With big help from people on here, the wiring of the beast has begun. Every time I think I understand it it kicks me in the face. Starting to slowly get now. I think.

Regarding the wiring I'm using a m-unit and m-button but after market switch gear.
The switch gear I'm using has three wires for the lights, dip main and a common as do the indicators left right and common and two wires for the horn. My issue is I don't know where the common wires go. I know they are live.
A wiring diagram if anyone has one would help. Thanks for looking.

If you look on mr t build thread he put a wiring diagram  on for the m unit .  May help you out

Thanks buddy but it was no good for my set up.
For those who are interested after a lot of trial and error the common is the live that goes to the m-unit.

Well a late one tonight. I've wrapped the exhausts that took an age.
These 4-1 exhaust systems are a bit of a pig to fit though. Anyway it's another job done.

Ok, stupid question time..........why do you bandage your down pipes?

[onethumb]

Hi Julie, the scientific answer is that the retained heat helps the gases flow better and helps keeps the optimal operating temperature more stable. The real answer is that the previous owner had sent the old one scraping along some Tarmac and I didn't want to shell out for a new exhaust. I'm already about a grand over on the spend!!

The bandages will help the scrapes to heal properly.  Come on Julie,  I thought you knew that.

Oh yeh and what Mike said.

So I've had a massive issue with the engine so I'm back to where I was back in October. This is a bit disappointing but it needs to be right.
