 It took me a while and some research to figure out how the GM unit works a=
nd though it is typical of modern alternators it is radically different tha=

See you in GA.

Morning Dave,
Thanks for the explanation=C2=A0as to why it's drawing 4 amps.=C2=A0 After =
more research there is a Denso alternator that is a 4-wire connection just =
like the Lucas alternators.=C2=A0 If I had bought that alternator I wouldn'=
t have a problem with the always hot brown wire.=C2=A0 I'm going to do what=
 others have suggested and just connect the small brown wire to the big bro=
wn wire and find a source of ignition (white wire).=C2=A0 There are two cho=
ices in the engine compartment, the distributor and the fuse box.=C2=A0 I'l=
l look things over today to see what it's going to take.
Hope to see you later this year :)

 I don't know about the Nippon alternator but if it uses the same regulator=
 as the Delco CS130 and if you have the IGN light connected the regulator w=
ill turn on and try to generate current even though the alternator is not t=
urning.=C2=A0 That four amps is the field current.=C2=A0 Applying power to =
the IGN light will cause current to flow into the regulator which turns eve=
rything on.=C2=A0 In normal operation, switching the key off will break thi=

This works quite differently than the boot-strap operation with which we ar=
e more familiar and is typical of alternators of our vintage.
But then, I am not familiar with your alternator and this may not be the ca=
se. But that is where I would start.

I'm trying to troubleshoot a problem with the new wiring in my TR6.=C2=A0 H=
ere's the configuration:
1) Mini Denso 70 amp alternator 3-wire=C2=A02) New wiring harness from TRF3=
) Positive=C2=A0cable connected to battery4) Between negative cable and gro=
und I have a fuse inserted with a small amp meter (this way if a short occu=
rs while testing the fuse will blow before damaging anything and I can read=
 the current draw if/until the fuse blows)5) White wire at distributor disc=
onnected6) No dash instruments connected7) Rear harness not installed yet8)=
 TBI power connector not connected9) Harness in engine compartment mostly c=
onnected=C2=A010) Alternator connected11) Fuse between brown and purple wir=
es is NOT in place

When I connect the ground I immediately start showing a 4 amp draw.=C2=A0 W=
hen I disconnect the small brown wire on the alternator the current draw di=
sappears.=C2=A0
The wires area connected as follows.=C2=A0 The brown/yellow wire goes to th=
e (1) connector on the alternator for dash light.=C2=A0=C2=A0
The small solid brown wire goes to the (2) connector on the alternator call=
ed "switched live" from the battery.=C2=A0 Currently the small brown wire i=
s always live from the battery per Triumph design.=C2=A0 If the "switched l=
ive' note means the brown wire is supposed to be cold when the ignition swi=
tch is off then that is likely the problem.=C2=A0=C2=A0
All of this tells me the brown wire needs to be from the ignition switch on=
 position and only live when the ignition is on.=C2=A0 I don't have any way=
 to really test my theory because I haven't got the engine running yet and =
won't for a few weeks.=C2=A0 I'd like to resolve this before I go much furt=

Thanks,
