Sun Tachometer Retrospective

[AnobleL74]

i love these old sun tachs also, but after owing 2 vintage sun super tach ll that only worked erratically, i tried all the gismos and tricks to fix them but finally i gave up,
problem may be because my chevelle and truck both have HEI.
ended up with a $50 bosch mini tach from advance auto that looks retro like the sun tach and works perfectly.

I replaced the batteries today as described above and that didn't do it.

I'm going to make sure the "new" batteries are not dead and after that I'm out of ideas.

Any suggestions?

Thanks in advance -

Fixed it.

I checked the removed batteries and they were still at 1.36 volts.

I cleaned up one of the contacts, which had some corrosion on it, and put them back in with some dielectric grease. I'm back in business.

This September that tach will have been in use for 53 years!

After the Crome Small Half Face Sun Instruments also made a Sun Tachometer, mine has the Green Line 0-10k almost a full sweet Sun Tachometer Green Line. The Green Line Sun Tach made first, the the Sun Super Tach Blue Line 0-8k came out near the end of 1967-68 year.
I have the Sun Tach Green Line and the Sun Super Tach Blue Line, then came the Sun Super Tach II Blue Line.
Both mine have been converted to Electronic by Williamson’s Instruments.
The Sun Super Tach Blue Line 0-8k is for sale, it's never been installed, it has the Williamson’s Instruments schematic with all the installation part's.
I know this is a 15 year old post.
I wanted to let y'all know about the my Sun Tach green line and my Sun Super Tach Blue Line, the Blue Line 0-8k rpms is up for sale, it carries Williamson’s Instruments Life Time Warranty, Crome Cup with acron nuts in the back.
I haven't learned how to post pictures yet.
Contact me through the sight and I will try to send pictures of the Sun Super Tach 0-8k to y'all if interested, $400. already converted by Williamson’s Instruments about 6 years ago.
Thank you for all the information, now y'all can look up the Sun Tach Green Line 0-10k.
