Questions

Can the 3780 also be mounted in dash?

Asked by: Iowabucks
Thank you for your inquiry. The outer cup on the 3780 is removable for calibration access. The inner cup will drop into a 3-3/8" hole. You will be responsible for fabricating something to hold the tach in the dash hole.

I have an older 3780 tach that I need to modify the wiring to mate with my factory harness. What gauge wire does this tach use? I can count the # of strands in each wire, but I do not have a micrometer to measure the diameter of the individual strands.

Asked by: stagedgs
Thank you for your question. The 3780 Tach has 20 gauge wire leads coming off the back.

Hi, do you supply replacement bezels as I have damaged mine. Uk customer.

Asked by: Bugman125
Hi Bugman, thank you for the question. Since the bezels are actually machine pressed on, we do not offer them separately as an accessory or service item. We can replace a damaged bezel, but it would have to come into our factory in the U.S. for that service.

Is the tach waterproof? Want to mount outside on the hood of a 1972 roadrunner...if not do you sell any that are thanks!

Asked by: Mikey340
Hi Mikey, thank you for the question. We actually do not offer any completely waterproof tachometers. We offer a several Pro-Cycle and Marine tachometers that are water resistant on the front only, but nothing that would be recommended for outside hood mounting that would be exposed to the elements.

I have an older 3780 with the "long life bulb" and it has burned out. I found out the hard way that it is not serviceable, and ruined the aluminum bezel around the gauge face. Can AutoMeter repair the bulb and replace the bezel for me?

Asked by: Johnny5
Hi Johnny, thank you so much for contacting us. We're happy to help you with repairs to your tach. You can send it right to the factory here in Sycamore and we'll get you taken care of. Our s3ervice information form can be found here: http://www.autometer.com/media/Service_Form.pdf Hope this helps!
