Got the planter out today to check it over and want to try and get the monitor working for this year. Planter does a good job, but the indicator lights weren't working on the monitor at all last year. I did wiggle the connector with the 10pins in it, and I got a few blips of light out of it. But I'm wondering how is the sensors supposed to check out? They have 3 wires going to each one, a red, green, and black. What kind of resistance should I get through the sensor? or should I? or how does the system work? (What wire does what?) The wires have some corrosion, so I'm going to check them out and see what that does. In the meantime, thanks for any help. -Wes

HI WES,

WHAT BRAND AND MODEL MONITOR ARE YOU USEING?

RED WIRE IS POWER @8 VOLTS. GREEN WIRE IS SIGNAL RETURN TO MONITOR. BLACK IS GROUND.

CLEAN YOUR CONNECTIONS WITH ELECTRONIC CLEANER OR EITHER (STARTING FLUID) . DO NOT USE WD40 OR ANYTHING ELSE THAT LEAVES A RESIDUE.

I CAN HELP WITH MOST ANY MONITOR PROBLEMS----26 YEARS EXPIERENCE WITH AG ELECTRONICS.

Hey John..! We're using an AC branded monitor that looks Identical to the Dickey-john monitor on the older plate planter we have. Exact make/model, I'm not sure without looking..I'll check on that tomorrow for ya. But it helps knowing what wire is what now. Me and Dad were looking busy checking resistance through the wires..lol We were having trouble getting the meter to show a good circuit on the black wire at the plug--not sure which of the three wires we were on at the sensor connector though. As for checking the sensors..I see that Shoup has a tool for that, but, if I leave the green and black wires hooked up, and set my meter on the red wire, and drop seeds through the sensor, won't I be able to see a reading on the meter from the red wire? Thanks for your help! -Wes

WES,

THE SENSOR DOES NOT PRODUCE POWER OR ANYTHING WITHOUT 8 VOLTS IN ON THE RED WIRE. GREEN WIRE IS SIGNAL BACK TO THE MONITOR. JOHN DEERE OR KINZIE DEALERS IN YOUR AREA SHOULD HAVE A SENSOR TESTER. YOU WILL HAVE TO TAKE THEM ALL OUT OF THE PLANTER FOR THEM TO TEST. MAKE SURE YOUR PLANTER HARNESS IS IN GOOD SHAPE. NO SHORTS WHERE THE WIRES RUB AT THE UNITS AND BY THE FERILIZER BOXES.
