I need a quick fix for my alt problem, so I can drive this weekend. I have
a few late alternators but they are negative ground. I was looking at a
Triumph site for a conversion. I have pasted the steps below. can it be
that easy? Swap a few wires, and install a different alt? I am just
looking for a fix by Sunday. Any ideas? here are the steps:
There is an article in the April 1993 issue of British Car summarizing this
conversion - the following is a summary of the important points, with
additions based on the experience of VTR members.
Remove the battery
If you have a radio, remove it.
Remove the central panel in dash and reverse the wires connected to the
Ammeter. Replace panel.
If you have an electrical fuel pump (non-original on TR-4), and it's a late
model SU with a diode across the points rather than a condenser, reverse
the connections to the diode.
Connect the (-) post of the coil to the wire going to the distributor, the
(+) post to the wire going to the ignition switch.
Replace the battery, with the terminals reversed. If you are using the car
as a daily driver, I'd strongly recommend that you replace both the ground
strap and the positive lead going to the starter solenoid with new cables.
It's cheap, and will give you a better connection, which means more
reliable starting.
Disconnect the two leads to the generator. Temporarily connect one end of a
length of wire to the positive terminal of the battery. Touch the other end
of the wire to the F terminal on the generator (the one the smaller lead is
connected to, wire is brown with green stripe) several times briefly. This
repolarises the field windings so you get the proper output.
Reconnect the two leads to the generator.
That's it - all the electrical devices on the car will now work like
normal. You can install a new negative-ground radio, or other electrical
accessories. I put in an electric windshield washer pump - much better than
pushing that stupid button! Feel free to ask the VTR mailing list if you
have any questions.
