Ahhhhh These cables dont replace the 'brick', the T4 has that interface built into it, so if yours does break then you will need a replacement.

I'm guessing you have a Testbook 1, 2 or 3 that uses the DTC0006A at the end of the extension cable?

Its been removed!

and what !!!!

Was the fault fixed that caused it?

I have sent you a PM

You will also need the hardware, its not just cables and software lol, my location is as per my profile details. Sorry but i didnt download them!

Nothing, it was given to me by my local garage, its a trolley system with printer and a microcheck unit for pre '95 cars, the OS on the laptop was corrupted so rebuilt that and once i had made my cables it all worked perfectly :D

Wanna buy mine then at that price ;) Wouldnt work with a 1998 L series :(

Where on earth did you get this from?

If you dont find anyone local, you can use mine.

Is that a typo?

I have a testbook/T4 system here doing nothing but im always hesitant to offer its use as a lot of members don't fill in their location so i dont know if it would help or not!

Well it wasn't planned that why as i made them up on the fly but yes resistors are on the left and the j1962 config on the right. i would have liked to use a single stackable rotary wafer switch but again couldn't find any and new ones were quite expensive to use on something that may not have...

My DIY cables are finished, i needed to make the DTC4007B extension cable and a number of J1962 leads, in the end my switch box contains the Blue, Red, Yellow and Green cables. It was fun making them and couldn't have done it without the help of my local MG dealer who allowed me to take their...

Spent the morning at the dealership metering out the cables, found the 12 way connectors so will order them monday and start making some new ones with a switch box to do all the J1962 cables in one.

Well i do appreciate you taking time to reply Colin :) I'm not sure when you looked at the cables but the 61A (made in 2001) that i have definately has a 47 ohm resistor in series with the K line, the L line is straight through. However the 1996 Grey lead is straight through but has the 47 res...

I have a T4 system which i am still getting operational and just down the road in Olney so if you dont have any joy and i get it all working, your more than welcome to use it.

cable info wrong - please stand by

They dont have a support contract anymore, thats why they gave it to me! At the start of this thread BBS Guy said he could supply schmatics for any lead so i'm hoping he will be along soon, the cables seem simple enough, they use loops on pins for identification and some have a 47ohm inline...
