Wiring issues

[Paul]

Hi,

Just purchased a MGTD (VW Based) that was sitting for over 19 yrs.  There are a number of wires disconnected and hanging under the dash. Of course there was no manual or wiring diagram available.

Anyone know where I can get a wiring diagram??

Hi Paul,

Go to the Download Manuals page (link in the left sidebar). After the “acceptance” page, scroll down to the bottom. Part 7 under Classic Roadsters, Ltd. is a PDF of Classic Roadsters LTd VW based Duchess schematics.

One of the pages in that PDF is specific to the dashboard. It may not be exact for your car. But it will certainly be close.

Thanks Paul. I will give it a try.

If it looks like someone had numerous guage problems, it is most likely because they all share a common (but bad) ground.  I say this because the guages get their “hot” wire from different sources and for many of them to quit would mean simultaneous failure of all the senders.  Unlikely.  The first thing to do is make sure that you have a good ground from the negative terminal of the battery to the guages.

I like Roy’s theory.

Boy we do love solving stuff eh? Even before there’s a problem!

All Paul6221 said was he had loose wires hanging down. And we immediately know there was a bad ground somewhere. What if the loose wires ARE the ground wires?

Just kidding guys. Really.

Paul, what they said does make sense. But since you are starting from scratch, it would be a good idea to trace everything under that dash. It might be possible to disconnect the dash harness (if there is one) from the car and then remove the entire dash. Lots easier to rewire that way.

Thanks guys for all your input.  Paul, I downloaded the wiring diagram and am now in the process of marking the color coded wiring with the numbers showing on my wires (what fun).

By the way, do you normally use a flat style steering wheel or the recessed style on these cars.  I have a recessed style, due to signal light lever, but it doesn’t leave much room for the SLIGHTLY large belly.  If you use the flat style what do you do about the signal light lever?

Thanks again

My steering wheel is flat.

The VW turn signal lever is cut at the first bend (furthest from the column) and heated and straightened at the bend closest to the column.

 My London Roadster has a flat wheel. The turnsignal lever is cut off a near the steering column. A piece of chrome pipe which is slightly flattened on one end slips over the shortened lever and is held in place by a very small screw that runs thru a hole in the pipe and the lever.It’s finished of with a small knob on the end of the pipe.

 On another VW based car I used a shiney cap from a ballpoint pen to attach to the shortened lever. It worked well and looked good . I removed the clip which was connected to the end of the pen by breaking it off and then filing what was left smooth with a small file.
