Powerhouse Posted February 1, 2008 Report Posted February 1, 2008 Any ideas on where to find a six volt tach? I can't seem to find any. Quote
Gwellman Posted February 1, 2008 Report Posted February 1, 2008 I have heard that Westach will supply them, maybe a sort of special order. But I know they have done it in the past. Check their website, these won't be listed, but I think you can contact them. Also check ebay, Sun made them (I have two that I bought new, still working fine). You need the model that uses and sending unit. They made a 6 volt pos ground 6 cyl sending unit, they come occasionally on ebay. Quote
Normspeed Posted February 2, 2008 Report Posted February 2, 2008 Check this site. Click on the 6 volt link to the left. If they're having a buy one get one free sale, let's split it and I'll take the free one:D http://www.westach.com/ Quote
1948Skip Posted February 2, 2008 Report Posted February 2, 2008 Oh Normspeed, Thanks for the laugh this morning. Skip Quote
Guest P15-D24 Posted February 2, 2008 Report Posted February 2, 2008 Works great, little pricey but not too bad. I got creative for the mounting and used a PCV case. It's 6v, pos. gnd.

gspineda Posted February 2, 2008 Report Posted February 2, 2008 I bought a tach from APT Instruments. Part number APT-TAC 6 Their web site is www.tachshack.com/sixvolt.htm. About $150. Iv'e had it for over two years and still working good Quote
James_Douglas Posted February 2, 2008 Report Posted February 2, 2008 I have a very small Westach in my Desoto. They made it up special for me. I will take a photo today and post it. James Quote
Dodgeb4ya Posted February 5, 2008 Report Posted February 5, 2008 Some of the old Dixco tachs (late 60`s had a resistor that you could remove to change to a 6cyl/6 volt. I still have it in my 52 Dodge P/U. Still works after 25 years! Quote
Powerhouse Posted February 26, 2008 Author Report Posted February 26, 2008 Howdy all, So what would be the best rpm to change gears if I have a 218 with a reg 3 speed...and also what would be the best rpm if I have a 37 chrysler OD installed? Any ideas how to find out...I don't know what size rear end I have...no laughing... Quote
rearview Posted February 26, 2008 Report Posted February 26, 2008 Picked up two tachs a couple months ago. One Sun unit off ebay that I bid low on thinking I'd never get it. The other was a different brand (can't remember) that was still NIB. I got it for $80 or so, expecting not to win the auction for the Sun unit. Well, I got both. I will try the new one in the next couple weeks, if it's fine I'll sell the Sun unit. Bob Quote
Merle Coggins Posted February 26, 2008 Report Posted February 26, 2008 Bob, What do you want for the Sun tach? Let me know if you decide to unload it. I'll come down and get it from you. Got a photo of it? Merle Quote
