No "Engine Preheat" Light

[jburt]

99 Beaver Monterey cat 3126. I removed the 4 house batteries and had them tested at Interstate battery today. All checked good so i reinstalled them without a problem. All cables were marked and went back on the posts they came off. Now the engine preheat light does not come on and the preheat does not work now. I have checked the fuses in the battery tray area along with the fuses in the bedroom and all are good. Is there an inline fuse to the ECM that powers the preheat switch on the engine that may have blown?

I would think that would be powered by the chassis batteries, not the house.

I think you are correct. I did nothing to the chassis batteries. I was just thinking about checking for a broken wire behind the batteries. Maybe a wire broke when extending the battery tray.
