Bobcat T770 doesn't seem to preheat

[Spike-MI]

Hi all, I have a "new to me" 2015 T770 T4 with 2800-ish hours on it. It has the deluxe panel on it. We are hovering around 30degrees here in MI right now and when I turn the key to the on position it says "wait to start" for maybe a second and then goes away. All my other Bobcat machines (2018 E50, 2007 T300, MT55, etc) are all requiring 5-10 seconds of preheat in the same conditions. What I have noticed is that if I leave the heater fan on and turn the key on, the fan does not kick on for 5-10 seconds. Are these units set up to kill all the auxiliary power draws during preheat? If so, maybe the preheater is working but not showing on the screen? Any ideas?

Thanks

This unit didn't come from Texas did it? Seen one or two of those flood units making there way to the NE. Could be a temp sensor issue. What is the displayed temp at start up? Post the sn#?:confused3:

Easiest way to check is w/ a volt meter..
Have someone turn the key on while some checks to see if your getting power "AT" the gp rail.
& "a second" isn't enough time to heat-up anything..

The glow plug wait symbol and countdown timer is on the left side cab panel, the one with the fuel and temp guages.

The right side panel doesn’t display a wait symbol.
