I am going to have questions. Specifically about a 59 G80. Original harness gone. Has been rewired (with all one color wire). I would like to find a wiring diagram and any other info available. The wiring is fairly simple of course but are harnesses available? Headlight shell switch is working but there's things wrong in there. I would have expected to find a rubber grommet in the lower back of the shell but instead there is weird round connector that sort of fits the hole, held in with three small bolts. Doesn't look stock to me. But then I've never had me hands on one of these before.
Also the original appearing battery box is there...with a very dead battery in it. It isn't coming loose. are these available?
Responses and advice welcome. Thanks in advance,

Bill E

The plug in the headlight is for quick removal for comp models.

A suitable wiring diagram is this - found off the Jampot Forum.

Wiring harnesses are available - start by poking around on the Jampot Forum.
They have their own spares scheme, and anyone can buy.

Look after that battery box !, and persist with it.
Worth its weight in donkey droppings, they usually get eaten by acid.

Any ideas on how to separate the leaked battery from the box? Without breaking it? I also found a Walridge ad in the AJS&MO magazine saying they have harnesses. This G80 was Ben Strain's who recently passed. I am hoping the family will allow me to get it running.

Thanks Rob C... the connectors on the plug are odd to me. Having a proper harness on hand might make it obvious how it originally connected. I also suspect a missing part. Grommet or mounting hardware maybe.

Are these engines prone to wet-sump? There is a small amount of oil in the tank and it leaves a few drops on the floor as a proper English bike should. It wasn't appropriate for me to drain the sump yet.

I'm assuming a wiring diagram will explain the headlight switch. As I found it, the taillight would come on when turned to the 1st position and then go off when turned to 2nd (headlight) position! Moved the wire one screw over and now the taillight lights in both positions. Is that how it was supposed to work?

Thanks for the responses...

Rohan...thanks for the link. This G80 has a front mounted magneto. Was the alternator optional? Looking forward to finding out if it and the dyno are alive.

Dyno ? front mounted magneto ? headlamp plug ? optional alternator ?
Either this bike isn't 1959, or isn't just a G80, or isn't very std. !!

Could it be a CS model, or altered to a CS model, or a complete bitza.
So, you may not find a wiring diagram that actually matches it. ?

The alternator was inside the alloy primary case, on the std G80 model circa then....

This bike should be about the easy bike in the world to identify and date. The engine numbers have both the model and year stamped on it. 59 = 1959

For the normal road bikes the magneto and dyno were replaced by the alternator and coil ignition in 1958. But dates can get a bit mixed because of model years vs calendar years.

As Rohan said if you have a 59 bike and a mag then something isn't standard G80

I think it is CS. Mag standard on them? Not possible to look at the vin now. It certainly looks like images I've seen of G80CS models. Except for the western bars. Anyway thanks for the info and I hope I get a chance to get more advice from you about it eventually. Depends on the owner's family.
