I'm in the process of fixing my tach using the following DIY

http://www.wrex-racing.com/docs/fd/Tach_Repair.pdf

Is there anyway to check that the tach is working without hooking it back up to the vehicle?

The reason I ask is I'm in the middle of a engine/single turbo swap, so the car wont be running for a bit. I'd like to finish this project and move on, but I haven't found a way confirm that the tach works without turning the car on.

Thanks

 

Not easily. You'd have to rig up something that simulates the tach pulse to make it move.

I'd just set it aside until you have a running car to test it.

Where have people been buying the replacement capacitors from?

 

Bump.

Still looking for capacitors.

 

Looking at the picture I can decipher this, the black one looks like a radial electrolytic 1uf 50V cap. The other one looks like a .015uf 50v film cap. Read the numbers on the side and do some googling on capacitor codes. You'll figure it out . Try Mouser or Digikey.

Those look about right. But I would look at your caps in person to verify the numbers.
