Re: [DML] "1980's Delorean Speedo Cable Fix"

Jan,

Well, it is easy when you don't go into the details of the process and just 
take the speedo to a repair shop. If you opt to do it yourself then you're 
right, it's not easy.
First thing to check is the odometer. This is a mechanically linked system 
(gears) and it should be correct. If the only thing changed was the angle 
drive and the odometer is off the angle drive has wrong ratio gears. You 
will need to replace it.
If the odometer is correct and the speedometer is off then you need to 
determine if is it of by a certain amount or percentage, ie. does it always 
read 10mph off (higher or lower) or if it is 10% off, ie. at 30 it will read 
33 and at 60 it's 66. If it's always the same number you can simply remove 
the needle and reinstall it in a correct position BUT, be warned, this is a 
very rare occurrence and is usually caused by a previous mechanic attempting 
a repair. When it's off by certain % ten you will need to recalibrate it.

I do have a plan to get rid of the angle drive as this is absolutely the 
worst part of the entire car. In my opinion an electronic (optical) sensor 
is the way to go here. I want to keep the original speedo and so I will be 
driving the original head with an electric motor.
