Really need speedo help
 

I sent my speedo out to hollywood speedos got it back and plugged it in no go so i posted about it someone said its a sensor i went out and bought a new speedo sensor no go so what now?Am i doing something wrong? Im at my wits end old speedo doesnt work either. Please someone let me know what to do.

Trying to remember... are you the one that the speedo works but not the odometer?

Or does nothing work?

nothing works supposedly rebuilt speedo and new sensor plugged old one in nothing

Not sure for your year, but is the pickup present for the sensor to reference?

Its an 82 I replaced the sensor with a new one.Not sure what you mean by pickup/ the one i replaced it with was identical. This system worked before i sent the speedo out to get repaired

I had a similar problem. Use multimeter and start from the sensor and work backward. Test the new sensor with a magnet to confirm it works. Then check wiring to tunnel to be sure there is continuity. Then check the wires from the tunnel to the speedo for continuity. Doing this you'll isolate the problem. In my case the brand new sensor was faulty.
