Hello guys,

Today a was a little bit confused, my original wire which was fitted within
the screen to the wiper motor was a little bit strange.
There are two thin isulated wires, then there is a wire around it within the
grey outside isulation.
Why is that? Two electric connection should be enough I think.

Greetings, John TA1434

Hi John,
You need only two wires for a 12 V DC motor. The wires are very
thin. I suspect that one of the original two wires is defect. May be then
some one took an easy way by adding a third wire instead of replacing the
original two wires. I see no other reason.

John,

I suspect that is not the original wire. It sounds like the replacement
wire sold by MOSS and others. The gauge of the 2 wires is way too small
for the current draw of the wiper motor. Even using the 2 wires as one
side of the circuit and the shield as the other is questionable. I
suspect it is originally sourced as some sort of shielded phone line.
When I rebuilt my windshield, I used some regular 14ga wire and covered
the small part that shows between the windshield and cowl with a length
of black braided shoestring with the ends cut off. Maybe not original
or concours but looks nice to me and is functional.

John - Charles Hill has it right. This is the wire furnished by Moss for the
TC wiper
motor. When I questioned them about the small size of the two insulated
wires they said they were supposed to be tied together to form one wire and
the thin copper wire shield wrapping inside the outer gray cover was to be
twisted to create the second wire. I was concerned that neither wire was of
sufficient capacity to carry the current and bought a heavier gauge wire
from a electric supply dealer.

Hi Charles Hill,
For the DC supply ( 12 V in this case ) you need two
conductors. But both conductors had to have the minimum thickness to carry
the energy required for the motor ( Wiper motor in this case).

So simply this :: you need an 1/2" pipe (hose) for your shower water
supply . OK.
But an Elephant shower you need a 4" hose pipe. That is about the Conductor
diameter.

In your bath the drainage pipe much bigger than ( min 2") the shower pipe so
that the dirty water can flow back.
If you have a shower pipe of 1" and the drainage is only 1/2". what will
happen ? Dirty water will never flow out. This is earth cable.

If the elephant is taking a shower in the garden you do not care about the
drainage. Water never goes through the drainage. That is what MG is doing.
Using the chassis for earth. ( drainage )

This is a problem in all "auto electric". Even in the modern cars.

Sorry for the mad comparison. So do not ignore the earth cable.

Hello Jerry,

Sounds reasonable... But a radio in a TA? I didn't have seen a lot of
T-types with a radio.

Hello Charles,

Indeed the inner wires are very thin! Maybe to thin.
I don't know the origin of the wire I have. It came with the car. I think it
is not original from the factory because the isolation is some sort of
plastic. Probably it is a after market looking original wire.
But the outer shape is a strange oval.

Greetings, John

Experiment time!
What is the current drawl in amperes of the wiper motor under load?
Folks with the original or correct heavy gauge replacement wiper motor wire:
What is the Voltage at the motor under load (with wiper running and and
blades wiping the windscreen/windshield)? Use a digital multimeter with high
internal resistance
What is the same voltage measurement at the other end of the wire (at the
voltage regulator) under the same above conditions?
Likewise measurements now with the Moss Supplied thin gauge wire.
Object: find the voltage drop across the suspect wire and determine line
resistance. I think we already know the answer; USE a heavier gauge wire.
Consider the condition of the motor along with any non lubricated bearing
surfaces over the past 50 years this most likely will also cause an increased
power consumption.
Now back to cleaning the oil puddle under the TC.

I'm with Madhu. If an elephant was taking a shower in my garden - I
wouldn't be worried about the drainage either.
