I was at a local car show and one of the vendors showed me an item called a pulse generator that screws on to the old sender on the transmission. It sends an electric pulse through a wire to the speedo. To calibrate it you find a mile marker, punch a button then punch another button at the next mile marker. My transmission seems to have the necessary driver. Has anyone used this system?
How well does it work? I like this idea better than the system that has a pick up sensor on the front brake drum that seems to loose contact after awhile.

I have used the type you speak of and it worked ok but would be a lot harder to install on a rear engine bus if thats what you have, mine has the sensor on the wheel, it is a dixson and ive never had a problem with it, also has a odometer which i like since some butcher in VA worked on my bus and destroyed the hub meter and the differential and helped me waste 2000.00.

ALL the big trucks have the left front wheel as a sending unit...there are thousands ,think I'd stick with that,just an opinion |

I have used one in my 04 for nine years now. No problems, also have a friend with one. I used one of the original wires already marked for the speedo between the front and rear electric lockers. I also needed a ground and a positive wire at the front and rear. I first used it with the spicer and later with a V730. It took a couple tries to get the calibriate right on. Using measured section mile markers and later checked with radar to verify. I used 3 miles at a time for greater accuracy. A speedo shop can use a counter to count the pulses in a measured mile and then simply set the dip switches per enclosed directions. I am also using a pulse generator for my tach. Look at Datcon.com for one mfg. Products and then Heavy Duty Industrial. Not the only way -- works for me. |

I have quite a bit of experience with a company called Nu-Metrics that manufactures Distance Measuring Instruments, for our DOT vehicles.
They also make a pulse generator that screws onto the transmission like the type Nelson mentioned...and they make a sensor that can work with the original vehicle speed sensor(if it has one and it's woking still), that has dipswitches like Craig mentioned.
These devices, along with a NS-50 "head" unit, are accurate enough to measure within plus or minus one foot over a 4000 foot distance PLUS give distance traveled, miles per hour and have a bunch of nifty features including things like Interval Measuring, plus a choice of Miles or Kilometers or Feet.
Very accurate, very reliable, if the vendor that Nelson talked to has a product that is remotely similar it is a good product.

PS: I know they will work with a negative ground.If someone has not changed your 4104 over from the POSITIVE GROUND check and see if they will work still work. I do not think they will. |
