Has anyone successfully used a sender other than the expensive and unreliable SW sender with a SW electric speedometer? If so can you provide details so I can do the same? Thanks! Ray W
I wired mine straight to the electronic output on the T-5 and it works like a charm. Unfortunately so does that gas gauge.
"Which SW sender.....the old 2 wire, or the newer "improved", 3 wire? a boner, The sender has 3 wires: Red is 12 volt +. Black is 12 volt -. White is signal out to speedometer head.
Personally i would not touch a new “Stupid Warner” electric speedometer . First one the speedometer stopped then odometer in the first month.So they sent a replacement . Well that lasted 2 months . The speedometer worked but to odometer stopped at 1500 miles. As we are down under I sent it to an instrument specialist and his report was its just plain worn out in several areas. Plus to get the speedometer out of our 49 shoebox i have to remove the dash. Odometer is still dead at 1500 miles but speeedometer still works. I like to have an odometer that works as i like to show we drive our cars.
NOTE: This sender puts out a square wave signal (i.e. digital). Looks like it is compatible. Google found these instructions; https://static.speedwaymotors.com/pdf/66582698.pdf
I concur. I went through 3 of them in my last roadster. Definitely not the company they once were. Sent from my iPhone using H.A.M.B.
Actually talked with 2 Stewart Warner reps at their booth while I was at Kalamazzo last Saturday. They said if I have the 2 wire sender, try the 3 wire sender. I would think they could have offered to send me a sender to fix the pos STEWART WARNER ELECTRONIC SPEEDOMETER their company sold me......if they really wanted to turn around the pos reputation SW has. They sure didn't seem too concerned. FSW
The instructions posted by trailer trash should be easy to follow. Sounds like the Jegs sender will work. Phil
I have had 3 SW deluxe electric speedometers and all 3 failed in one way or another. I talked to SW reps at SEMA the last two years. The first year they replaced the bad unit and low and behold, the odometer quit after 500 miles! The first one died at 7000 miles with the speedometer dying shortly thereafter. I called the engineer that exchanged the unit and he was surprised to her of two odometer failures. Last year I cornered yet another engineer and he admitted that they had a run of bad odometers but didn't tell the public. He offered ho help at all. Since my Sky Drive has never failed, I have decided to have Classic make me a look alike electric speedometer with my initials in the SW font. By the way, Classic guarantees their speedometer for 7 years. Try to get that out of SW!
Not just a electric speedometer problem! Bought a new set of "Wings" mechanical guages for my AV8 build. Sat on the shelf for about a year until the build was ready for installation. Picked them up and the speedometer needle literally fell off! Ditto the oil guage. S/W originally denied replacement because the factory warranty ran out . Eventually, after some arm twisting they exchanged the guages. Coincidently the needle fell off another guage shortly after the replacements arrived. Just bought a new one to avoud the hassle again. Keeping my fingers crossed they stay intact. Seems quality went off shore with production..Sad!
OK, it looks like "problem solved". I bought the generic GM 3 wire, 8000 pulse per mile sender a boner suggested from Summit Racing. I just checked it's accuracy and the odometer clicked off exactly 5 miles in a known 5 mile interval near my home that I used to calibrate the SW speedometer when I first got this roadster in 2003. It's cost is $33 compared to the $125 sender from SW plus another $18 for the square drive that is not included with the SW sender. So the SW part is more than 4x the cost of the generic part sold by Summit, Jegs and others. Ray W
