[6pack] alternator woes

[Bob Danielson]

If you don't have one, go to the AAW site 
(http://www.advanceautowire.com/tr2506.pdf) and download the free color wire 
schematic for your car. Dan Masters worked with a bunch of Triumph Mail List 
guys to come up with, what's considered by most, to be the best and most 
accurate wire diagrams for most Triumphs. In the 6-Pack Forum this is what 
we all use for diagnosing electrical problems.

However, as pointed out by Bob in his response, if the PO "rearranged" 
stuff......... who knows what goes where :-(

> The heavy brown wire goes directly to 12 volts on the starter.
> The brown white goes to the ammeter.
> The brown yellow goes to ignition light circuit.
> Unless a PO made wiring changes of course, then who knows??

> Good luck.
