Gearbox Transducer - DigiDash
Guys I'm after some advice.
My speedo stopped working the other night, I've checked obvious connections and they seem fine. Is there anyway to test the transducer in the gearbox?
I presume there's just the two variants, early and late dashes? Also, where's the cheapest/best place to get a replacement from?
they are 70 + vat new from vauxhall, which only leaves the breakers. It will be either an AK or AH transducer. will have that in big white letters on the side.
Yes - get down to maplin and pick up a 12 volt led.
Led to the Black + Brown wire with the ignition on should light up
Led to the Black+ Blue/Red wire with the ignition on should flash when the sender is turned
You might have to put the LED between the Brown and Blue/red wire - cant remember at the moment if its a pull up or pull down output.
You can do the same with a multimeter instead of the LED - you'll find the pulse is 80% high and 20% low approx
Cheers for the replies, for some reason I didn't get any email notification.
I'll order one from a scrappies tomorrow, its the later spec one that I need...whichever code that is?!
