T7 speed pulse from 7 pin socket.

Does anyone know pin the speed pulse comes from with a t7.200 with radar? Got a stocks seeder that won't pick up and stocks have said it prob needs the wire moving to a different pin as it's using a radar but they didn't know which one. Stocks plug just uses the center pin and pin 1 at the mo

Thanks, it was in 1 and not working. Moved to 2 to try and still no luck. If I use a multimeter there should be a pulse to test the tractor? If that seems ok will have to phone stocks dealer Tommorow

Tested socket and there's 5.4v when stationary and then that drops as you increase speed?

different scenario, I use the plug for linkage up and down on my trimble gps . remember trimble man saying that they use a strange voltage

You need to use the frequency / pulse count function on your meter (if so equipped). Using the DC voltage function on the meter will just ‘average’ the signal. No good for you.

0 to 10v DC linear on linkage position. Different kettle of fish chap.

thanks, put fert tub on today and it's working on radar and transmission or wherever the other sensor is so must be an issue with seeder

Yes it will be a Sq wave signal.
