Spitfire alternator wiring question

[nightrunner68667]

My starter solenoid has a brown wire on both sides, I am thinking that both brown wires should be on the battery side????? is that correct??

also the car has an aftermarket alternator with the big brown wire on the post marked "batt" where do the small brown wire and the brown with yellow tracer go on this alternator???

Thanks for the help!!!!![SUB][SUB][SUB]!!!![/SUB][/SUB][/SUB]

Brown Wires:
You are correct. All the brown wires (large and small) should be on the battery cable side of the starter solenoid.

Alternator:
That looks like a GM alternator. The large brown wire shown on the alternator should go to the battery cable terminal on the solenoid (where all the other brown wires are).
The old Lucas alternator plug will have two or more wires in it. (Depending on the year of your car a which alternator was used). Look carefully at the old plug. There will be a large brown wire in the plug. It should go the threaded post on your GM alternator where your existing brown wire is. (Use both big wires (the one on the alternator now and the one in the old Lucas plug) The GM alternator puts out more current than the old Lucas.
Note the two little spade lugs on the GM alternator... one will be labeled "1" and the other "2".
Go the the parts store and buy the GM alternator plug... they are cheap and readily available.
The wire that goes on the "2" terminal goes to the threaded post on the alternator where the brown wires go.
(It is a "sense" wire).
The wire from the "1" terminal will connect to the small brown/yellow wire in the Lucas alternator plug (for the warning light).
