This is a New Holland with under 900 hours on it. When the turn signal switch is moved to either left or right, both of the front indicators blink slowly and dim, nothing at rear. If the flasher switch is pressed the same thing occurs. when the light switch is turned to the first position, the rear running lights come on dimly, the second position makes the headlights work with no change at the rear.Both beam settings and high dip switch seem to work fine. **The rear work light doesn't do anything unless the key is on. Activate the flashers, with the key on, flick on the rear work light, the rear turn bulbs, along with the work light itself will all pulse in time with the front indicators, very dim. **With the key off, but the light switch on, with the rear work light switch on, the #1 relay clicks in time with the front indicators, as does the fuel pump shut-off relay... Havn't bothered to verify what the # 1 relay is for, the layout does not exactly match any version options in the owners manual I have to look at/ Thank you New Holland... This is a 4x4 manual transmission model,no shuttle, no cab, no front lift, a fairly straight forward model as these things go.
I verified good ground to all four corners.I checked the ground under the console, and at the rear left. have checked the wiring harness. have tried another flasher unit. have unplugged the multi-function switch. Have wasted half a day...
Help?

You have a bad ground somewhere. The electricity is trying to find an alternate path to ground.
