Power source for Trimble 250

[Flat 10]

I have a Trimble 250 and ag15 antenna. It seems very sensitive to changes in voltage, for example it often used to turn itself off when the sprayer was turned on or off (it shared the same D plug) now I’ve wired it to the cigarette lighter but these are poxy and the slightest bump turns it off. Where do others take their power from please?

Get a dedicated D plug, my matrix pro was doing the same, used a small screwdriver to tighten the female side and its stopped losing power intermittently.

Direct to battery if you can, but I have an EZ Guide 500 on the Quad that runs on the cigarette socket with no problems all.
Should add that there is a slave car battery strapped to the back of the bike, to keep the slug pelleter going at full chat...
