Just installed a 6 volt positive ground tachometer in my 1948 Ford convertible.The car has Columbia 2 speed axle.The tach works beautiful and at 3000 rpm at runs 50 mph with 4:11 axle ratio.I then shift to overdrive and car turns 2100 rpm at 50 mph.Wow what difference.Would highly recommend the Westach tachometer a high quality unit and easy to install.
 
Dave, Westach is a great company and have been in business since the 70's. Glen Westberg and his brother sold the company to one of their main guys a few years ago and it's nice to know the company is still maintaining the same quality in their products. Glen was a personal friend and has since passed away.
 
Dave, I bought a Westach positive ground tachometer a couple years ago to use in my 35 fordor sedan. I haven't installed it yet, but it's good news to hear yours is working well and that you're happy with it.
 
Hi Dave, I just looked at their web site the tach I looked at has a 2inch face with chrome bezel at $144.65. did you have to drill the dash? Thanks for any info Jack. just xmass shopping for my 49 ford.
 
Installed on the column. Did not have to drill any holes. Very pleased with the appearance.

I have always wondered if the installation of a tachometer into the ignition has any effect on the ignition system. What say ye "electrical geeks?"
 
Under normal conditions, there is no effect. The tachometer just reads the signal from the tach and imposes a negligible load. I did have a situation where a tachometer controller developed a short and shut down the ignition system by grounding out the coil. It was a failure of the module and when the controller was unhooked, the engine ran normally.
 
I have been using the Westach 6 volt tach for about 7 years, works great.

Has anyone hooked up their optional light?
 
6V pos ground in a 1948 Dodge Power Wagon. I did connect the bulb. More accurate than my speedometer. Especially since the tac reading is 1/2 the speed in 4th gear, ie 2500RPM = 50mph

I purchased one for my ‘51 F1 but while I waited for it to be built I found a “football tach” on eBay for $20.00 and now I can’t get myself to remove the football tach for the westach... so the westach sits in its box on a shelf.
 
It just refers to the football shape on the face of the gauge.

Bosch currently makes a Tachometer that is very close in looks to the original Sun "Football". It is a regular 12 volt negative ground "Motor" tach. The main difference is that it has a 0-8000 RPM range.

I can tell you how to make one run on 6 volts positive ground.:D
