RugerLuger Posted November 25, 2014 Report Share Posted November 25, 2014 I recently purchased a 1972 510. One of the previous owners swapped the original instrument cluster w/o a tach for a cluster with a tachometer. I found the original cluster with a few other spare parts in a box. The original Gauge set has some sort of adapter or sensor attached to the rear of the speedometer. It is a metal cylinder with two wires coming off of it. The speedo cable hooks into the back of the adapter/sensor. Anyone have any ideas on what it is? My Google and forum search powers have failed me thus far. Quote Link to comment
datzenmike Posted November 25, 2014 Report Share Posted November 25, 2014 A picture might help. Is your 510 an automatic by any chance? The automatics has a speed sensor on the speedometer cable, but not at the gauge. Quote Link to comment

tr8er Posted November 25, 2014 Report Share Posted November 25, 2014 I think most of us broke our spendometers looong ago. Quote Link to comment
RugerLuger Posted November 25, 2014 Author Report Share Posted November 25, 2014 Sorry I thought i had inserted a photo. It currently has 4 speed manual married to an l20b. The current speedometer in the vehicle works ok (a little bouncy at lower speeds). But when i was looking through the spare parts and saw this ... thing on the back of the speedo it peaked my curiosity. it has a label marked 211 and some Japanese charecters. Quote Link to comment
MikeRL411 Posted November 26, 2014 Report Share Posted November 26, 2014 If all our old Datsuns had "spendometers" on them to tell us just how much we had spent on them, we would all be wearing brown pants. Quote Link to comment
datzenmike Posted November 26, 2014 Report Share Posted November 26, 2014 It currently has 4 speed manual married to an l20b. Might it have been an automatic at one time? Quote Link to comment
RugerLuger Posted November 26, 2014 Author Report Share Posted November 26, 2014 Might it have been an automatic at one time? Its possible. I never thought to look for any signs of it being an automatic. Its currently in storage for the winter. Quote Link to comment
datzenmike Posted November 26, 2014 Report Share Posted November 26, 2014 If all the parts were from another 510, that will be hard to do. Quote Link to comment
Guest Rick-rat Posted November 26, 2014 Report Share Posted November 26, 2014 If you get your "spendometer" working, it will probably shock you :angel: Quote Link to comment

qwik510 Posted November 26, 2014 Report Share Posted November 26, 2014 That unit was on the back of my cluster too. 1970 with auto trans. Quote Link to comment
datzenmike Posted November 27, 2014 Report Share Posted November 27, 2014 Then it's an emission related thing. Standards have transmission and clutch switches. If in 3rd ot 4th and the clutch is up then likely you are driving down the road. Not so on the automatics. There is a speed switch spun by the speedometer. Maybe it turns on at 20-25-30? MPH and activates/deactivates the dual points? One of the Datsuns has one on the speedometer cable out in the engine bay. I've never seen this kind. 1 Quote Link to comment
