Re-wiring 2a issues

It is a replacement for an alternator that did have an external regulator and the unused one was not removed?

Anyway, that helps a lot to actually know what I have. Who would have thought it?


So could anyone set me straight on the location of the cold start switch in the head?

On the top of the cylinder head next to the thermostat housing. Roughly triangular in shape, held by three small screws.

Really?

Damn, I thought that was the temp sender...

Temp sender screws into the RH side of the head, the bit the thermostat housing is bolted to.

Much appreciated!

One more, if you'd be so kind.
The diagram shows that the cold start switch in the head connects to a "cold start switch on control"

Is this a relay normally located behind the instruments?

Thanks

No,it is a switch on the choke control. In the post 67 model it is p/n 563318, clamped around the plastic tube that the rigid bit attached to the choke knob goes into, and has a plunger that is displaced by this bit when the choke knob is right in. The cold start switch in the head turns on when the engine is warm, and if the choke is still out, this switch on the choke control is also on, so that the orange "cold start" light will illuminate.

yup

I tend to think of it as a warning "hey, dink, yer choke's still out"

That relay you posted a pic of....

Could be for several things...

I have seen a schematic diagram where a relay was used to engage the starter switch

I have seen relays used to handle the headlights on main beam

It could have been used virtually anywhere that someone wanted to reduce the current flowing through a switch.

None of my 'standard' schematics for a 2a have one.
