Wire the black lead to the coil negative, and the red lead to the coil positive.

Any advice gratefully anticipated!

Edit: Looks like it's a bad idea: Series 2A Motor Removal

It was an incredibly educational and worth while experience rebuilding my gearbox myself. I'm an Electrician, but following the old Series III manual and getting a bit of advice from here got me through. I'll not fear building a Series box again now. It would be a great oppurtunity for your boys too . I'm guessing you already have another box lined up? If you are going to rebuild your own box though, list down everything that is wrong with it now which will make it easier to identify the parts you'll need when you have it open.

Mine crunched between 3rd and 4th which meant replacing the 3+4 synchro, probably the most expensive part of the box ($200). A standard rebuild kit including all bearings, seals and gaskets will cost you around $150.

Doh! Didn't want to risk connecting it that way at first. Put it in this morning, cranked her up, and worked fine..

Many Thanks,
Wolf

Glad to hear you got it working, Wolfman. I was going to point you to the photo of mine a page or two back, but you don't need it.

However, you might have a read and see the grief we had with the wires wearing through. Could be helpful.

TJ,

Thanks. We had a spare we bought (cheap) from Peter, which he said had been rebuilt by somebody already, so we thought we'd whack it in and see how it went.

Having removed the old one, we decided to replace the primary shaft as the replacement box had been sitting around for a year or more and the primary shaft spline was a bit rusty. Below you can see what oozed out when we cracked ours open...

As you can see, the lubrication value in that was probably limited!

After pulling the primary shaft off the "new" one we discovered the retaining bolt on the layshaft was not screwed in - it was just sitting there loose. Terrifying. Made us wonder about the rest of the box, but we didn't want to disassemble it and after we had the replacement primary shaft back in it all seemed to work so we took a chance and fitted it.

Works a treat. Took it for a drive and everything's sweet.

So now we have the old one to rebuild when we have time and inclination. I agree it would be interesting and instructive.

How's everything going down your way?

The second photo is the old gearbox still in situ after we had it ready to lift out. You can see the new exhaust, re-routed to leave the area behind the rear diff free for the long-range tank.

Cheers,
Lane.

Yes, I've been reading through this thread, and saw what you meant about the wires wearing. I have checked mine, and they seem to be ok. Then I've just put in a brand new dissy, so I shouldn't have that problem.. (So Far that is )

My problem was trying to get the electronic one working. (Hard to do without the proper instructions).. And noticed that you had the same one. So I asked..

Cheers,
Wolf

And the electronic ignition fitted.
