Is it posible to connect my factory surf tacho to my Chev v8

Postby Dannz71 » Sat Jun 15, 2013 10:13 pm

I have a 350 chev in my ln61 surf that used to have 2lt diesel in it, and I was wondering if I can connect up my tacho to the v8 easily? has anyone done this before? is it hard?
don't reali wana spend too much, just if its easy..
cheers for your input

will be the wrong voltage on the tacho, anything electrical in nelson do a converter, otherwise can you find a petrol dash to swop it over?

don't think the voltage is an issue as the truck is all 12 volts as is the v8 ignition.
and wont I stil have the same issue if I put in a petrol dash as they are all 4cylinders and the chev is 8 cyl, think my tacho reading will still be out by double as itl be getting 8 pulses not 4 pulses...

as long as you fit the petrol dash (4cyl or 6cyl), just fit a pulse converter. i think there is even a jaycar kit.

Efi gauge clusters operate on a low voltage input signal. Older ignition systems like a coil dizzy setup output a higher voltage so a converter is needed.

The ln130 gauge clusters have an adjustment pot on the back which can be set to allow a 4 cylinder cluster to work on an 8 cylinder motor. I got my 1UZ working with a factory petrol cluster. Not sure if the earlier gauges have the same adjustment but you will need a converter unless you can find a non efi petrol cluster with a tach that can accept the high voltage output signal from your Chev.
