Problems installing tacho

[Cannman07]

Thanks mate, I'll grab one from somewhere and hook it up.

Where would I get one of those resistors?

Go to jaycar and see if they have one single if not they have a pack with different sorts that does for 8.99, only one I can find listed as single is 10k 0.5 but you need a 0.25 / 1/4 watt.

This is the colour code for 10k 1/4 watt,

Good luck!

It says to use 10k .25watt I don't know if going double will cause a issue, your choice I know what I would do spend the 9 and get the right one as the installation tells you. Or try ebay or the web and get one cheaper if your not in a hurry.. Go to a tv repair joint they will have some or even a computer repair shop.

Whats known as a pull-up resistor, It needs to be 10kohm for sure but as far as the wattage rating there's little heat going to be dissipated by the resistor,
so 1/4w or 1/2w it wont be a issue.
Search for 5v to 12v pull-up resistors or tacho pull-up resistors

Yeah I thought so, but wasn't game to say just in case something went wrong, cheers.

Thanks for all the help, I'll go buy one tomorrow

Update on my tacho problem
After getting a 10k .5 watt resistor and hooking it up it made no difference so I emailed the SAAS tech support and after telling them all of the above they asked me to send the unit back so they could test it. It tested fine but they sent me a new one in case the other had an intermittent fault. Installed the new one with the same result as before so emailed them again and they said it has to be weak rpm signal as the smaller tacho works and the big tacho has power, they told me to I install a 1k .5 watt resistor but this didn't work either. I'm not sure what to do now as I've tried all suggestions. Any ideas at all would be appreciated.
