Good Afternoon Listers
As a follow on to my previous Listing regading wiring my ammeter....Several of
you have already provided good advice and I have placed my order with
BritishWiring.com for the wire and female spade terminals I will need to wire
up my ammeter.
I have studied the wiring diagram, I have the ammeter out of the dash (looks
to be the original Lucas ammeter), and I am ready to proceed when the supplies
arrive...but I must admit I am a bit nervous about doing this absolutely
correctly so I do not burn up my car...now or in the future. I found a write
up on ammeter installation in the Shop Notes but I must admit it did not make
sense to me. You all know I have been a Tiger owner only a short time so I
would really appreciate it if somebody could walk me through this by the
numbers. Before doing so let me lay out what I believe needs to be done.
>From what I can see, the dotted line on the wiring diagram for the optional
ammeter indicates that the ammeter must pe placed "in series" between the
generator/voltage regulator (Vreg).......and the starter solenoid/battery. So
that means I need to:
1. DISCONNECT THE BATTERY
2. Disconnect the brown wire on the starter solenoid that runs from the vreg B
terminal
3. Run that wire back up through the firewall and
4. Connect it to the + (inboard) terminal on ammeter
5. Connect a new wire to the -- (outboard) terminal on the ammeter
6. Run that wire back through firewall and
7. Connect it to the terminal on the starter solenoid from where the vreg
brown wire was previously wire disconnected
8. Connect ground wire from Tach to ammeter
9. Insert bulb wire
10. Put ammeter in dash
Based upon earlier advice I am using fully insulated terminals on the ammeter
and I will also add some electical tape on the back as insurance. I also can
probably save a little effort by running the wire to be connected TO the
solenoid through the firewall at the same time I run the wire I disconnect
FROM the solenoid.
Any secrets on running the wire through the firewall?
If I do not have this correct please correct any/all steps where I have gone
wrong.
Thanks,
Jim

Subject: Wiring Question
Hi All,
I am wiring up my ammeter and I had a question regarding the color/gauge of
the wire. The Wiring Diagram for the MkI shows the color of the wire as brown
for the connection to the voltage regulator (vreg) and the starter solenoid.
It also has the connection to the vreg going to the B terminal.
The Under Dash Wiring Diagram from C.A.T. shows the the color of the wire to
the vreg as brown/yellow and going to the A terminal.
Which is correct?
Also, does anybody know where to find brown and/or brown/yellow wire. I have
tried all the usual auto parts places with no luck. Online sources want you to
buy reels of at least a hundred feet. The one place I thought would
work...Britishwiring.com has a web site I can not seem to access.
Finally what gauge wire do I need?
As always...Thanks.
