Club 80-90 Forums

Hi Guys I'm new here so excuse anything i've missed, I think i've looked through everything and still can't find an answer.
I have a 1990 1.9 Transporter, that's mid camper conversion. I just got a dash on ebay with rev counter and a digital clock. The problem is it came from a diesel, I've got every thing to work but the rev counter is barely moving 1000rpm is the engine flat out. I've read that there is a pot under the white sticker on the back for adjusting it. Will this give me enough to make it work on a petrol? or should i be looking somewhere else?
Cheers Karl

what have you connected the tacho to?

The rev counter from a diesel engine runs from the alternator not the ignition. Don't know if you realised this but thought I'd mention it just in case!
Welome to the club too!

It was a straight swop for the old dash i just had to remove the bit with the glow plug light in and swop it for the same section from my old one. The rev counter is still on it's original circuit foil.

then it's on the wrong circuit

connect it to the alt

So if i get this right, either the tacho or the foil is specific to the petrol/diesel.
is it possible then to run a cable from the alternator and run it in to this circuit?

sorry missed a bit, where on the alternator?

The 'W' connection... If its there!

Thanks i'll give that a try, from memory i think it's the green wire.

Just thinking does this wire originate in the engine bay?

As your alternator is there... Then I imagine it would... Yes...

Very Smart. I'm talking about the existing wire, it being petrol. I was hoping i could just move the end in the engine bay to the alternator, hence my question where does it originate?

on the coil usually

but your 1.9 never had a tacho fitted.. so you'll have to run a wire from the alt

lovely thanks. That will be much neater than splicing a new cable in.

you will have to. as you haven't got a tacho feed on your coil
