I recently replaced a dead tach in my 88 exp and thought someone might be able to used the old broken one for parts. This tach does not work. It dose nothing at all. I don't know what's wrong with it. I just know it doesn't work. Sold for parts. Could be useful if someone needs the housing/face or maybe one could try and fix it. Asking 1$ plus shipping. I take PayPal only and only ship within the USA. Basically your paying what is cost me to send it to you.
