You’re very welcome my friend!!! I’m looking very forward to getting the car MOT tested Saturday so I should be able to start using it and get some more pictures on here!

Just so I understand correctlybrinkie wrote: ↑Tue May 01, 2018 12:06 pmIf you also have an audio signal generator, just hook it up to the terminals and apply a 400 Hz signal to test the speedometer. Your speedometer should show around 120 mph.
An Android phone will act nicely as signal generator, I am using an app called "Simple tone generator" (type 400 and then turn up the volume to max), but there are plenty other apps available. Use an audio cable with a 3.5mm jack connected to the phone and use something like crocodile clips to attach the speedometer signal cable to the phone.
thank you, yes saw the wee symbols, and as I already have 'bypassed' ALL wiring on the dash board , ie signal from speedo and its power are ALL fed direct to the small blue plug, and as SWAMBO doesn't worry about mpg then not needing the signal to/from the info/ ECUbrinkie wrote: ↑Thu Nov 07, 2019 9:09 amVery good, this is exactly how I bench test the speedometers! (I do have to cope with the same mess, though)
Actually, there is very helpful information on the speedometer print itself so you won't need the confusing information from HBOL. In technical terms, this is called a silkscreen (see more explanation here)
Near the blue 5-pin connector, on the solder side of the print, you can see the symbols of positive, negative and signal inputs. Negative is the one closest to the bottom edge of the print, positive is the one farthest away and signal input is in the middle. (All this information from memory)
There is one unused pin and one that carries the signal to the info centre, useful if you have an oscilloscope but not necessary, there is enough feedback from a working system if the stepper motor and the needle start moving.
Good luck!
Was about to suggest that! Presumably you've already found the part you need, they were available on eBay last time I checked.

Thanks, but I'm on 'android'Jaster wrote: ↑Sun Nov 10, 2019 8:09 pm
Probably wouldn't have helped in this case, but in general I highly recommend the 'EE Toolkit' app if you have an i-device: https://apps.apple.com/gb/app/ee-toolkit/id391792609
It's a really great reference to have and among many other things has a fairly reasonable SigGen built-in.
