Check engine light

[dirtclod]

When I turn on my rear aux power switch to run my sprayer pump, engine check light comes on. When I shut the sprayer off, light goes out. Why? Thanks!!!

What is the current rating on your sprayer? I know the aux port is fused, but just curious how close you are to the limit. To be clear, I don't have any answers... just curious.

Good question, I'll check that out.
