Monitor comes on with override switch momentary. Pulled ecm and bottom rusted through but looks OK visually internally. Checked grounds. Yellow light stays on. Previous problem was and still is won't return to idle with knob but will in increments if u hit override toggle a few times. Now monitor probs. I know ecm needs replaced because of bottom rot possibly or repaired. Pricey like everything but is there anyone that rebuilds them? And any advice on monitor as rot on ecm seems to have been there long before.
You need to provide a serial number for folks to have best chance to help.
