QUESTIONS:

I installed a 1478 tachometer in my project 1965 Ford Falcon electric car .I am using a HPEVS AC 51 motor with a Curtis 1239e controller and an optic isolator. The tachometer worked great until a couple days ago. Is the tachometer compatible ?

Asked by: electricfalcon
Hi, Our tachometers are designed to work off the ignition system on a gasoline engine. The signal is a 12 volt DC square wave, 50% Duty Cycle, 2, 3, or 4 pulses per crankshaft revolution. The power supply needs to be a regulated 13.6 Volt DC. Assuming you can replicate those things with your electric vehicle, the tach should work for you. Thanks, Jim

is 79.4mm the face or body diameter?  My hole is 72.2 mm. will this fit?

Asked by: Marty rein
Hi Marty, thank you for the question. 79.4 mm is referencing the hole size. Unfortunately, 72.2 mm is a size we won't offer. The next size down from our 79.4 mm tachometers would be a hole size of 66.6 mm.
