I have had this tach in my glass case for years and have finally decided to use it on the '40. I was talking to a guy up in Puyallup that does battery-free sender conversions, thinking I'd need one. When I got home and pulled this out I realized that the wires are plastic coated and started thinking that maybe it was a newer model that just needs to be wired up. Do you know the scoop? If I don't need the sender, does anyone know the correct wiring for it? Thanks!
I have an early Sun tach that doesn't require a sending unit. Mine is wired like this: green: neg. side of coil red: pos. power source (acc side of ign. switch or fuse panel) black: ground white: light circuit I have a Sun catalog is there a model # anywhere? Hope this helps. Tim
That sounds like the last '60s Sun tach I had and this one has the same color wires. That's what made me think I don't need the sender.
5Grand tach, wonder what the original intent was? Some industrial panel? Killer look, does it switch for different number of cylinders?
Kirk, Do you remember when..... http://www.jalopyjournal.com/forum/showthread.php?t=159309 (not saying you'll find All your answers there but..) Wonder if this works? http://www.jalopyjournal.com/forum/showthread.php?t=546149 . Last but not least on the wild goose chase list: http://www.tachman.com/sun.htm Maybe I should have posted That link first??? ? .
Huh? Somone posted that there would be a number and a + and - under the bracket, but they deleted their post. Anyway, here's what's under the bracket - nothing. Hmmm.
Now that I think about it, mine did come in a box with (I think) that same instruction sheet and that little envelope. Time to search for that.
It appears you have a marine tach and it sounds like it needs the matching transformer/sender. Is that the light that attaches to the front of the meter? Pretty cool. I have old SW and Dixco tachs but no early Sun stuff to speak of. According to the tachman, if you put 1.5 volts to it the needle should show smooth movement and hence it might be good. Here's what happened to Ryan's tach (scroll down the page) http://velvetoven.blogspot.com/
Yes, Marine. Sounds like it is/was 12 volts, at least that's what I surmised from : http://www.tachman.com/sun.htm It might be about a 1960 to 62 model? The EB-9A transmitter would be the latest 'brain' available for those tachs.
A friend of mine just picked up one of these for 15 bucks!!! I never knew that the light is actually on the outside of the glass. It does make it easier to change the bulb. I could be wrong but it was always my understanding that you bought the sender to match number of cylinders and the voltage of the car that you are using it for. The same tach would work on a 6 cyl or a 8 cyl with the correct sending unit. I need a sending unit for my red football Sun tach.
You have an older model that requires the sending unit, except that the pointer is much thinner than normal. Take it out of the cup and see if someone has already converted it.
HI KIRK If you have not done anything with your D series tach contact me and I can take care of you, no problem Jerry V [email protected]
Anyone have info on conversions that lose the sending unit on this model? Also changing the face from 3500 rpm to 7-8000 rpm? Any info much appreciated.
looks like military surplus I am going to guess air plane? Of course it could be a boat tach or even one for a flatty. Too many wires comming out of it for one with a sender. It should only have 2 wires comming out and one for the light if it uses a sender. How many wires actually go to the tach have you popped the case off of it?
