Tacho resistor

[Tonks4x4]

Hi chaps....

First time I have had chance to get to sorting this issue....

Running an ADU engine in an early 82 UR SWB.

Come to wiring the tacho...

I have the signal wired to the clocks and it shows idle but when revs increase the needle drops to zero.

I have some resistors (not the correct rating) but I am on the understanding I use a 2 ohm resistor to correct the input.

That should work but what wattage resistor do I need????

Ok chaps....

Had a brain fart.

It's a 2k ohm not a 2 ohm

All sorted now

Hello i have the same problem and happy to see this solution.
2 kohm resistor, but does anyone know how power in Watt? 1W? 5W? 1/4W

Thanks.
