TRU Voltage and Cold Starts

[jmarkows]

I have been rereading the 146 manual again and trying to wrap my head around the Electrical system chapter. Just for kicks, I loaded up the 146 tonight, connected ground power, and switched to Cold starts. It was above freezing where I am, maybe that makes a difference, but I'm wondering why I'm not seeing the TRUs outputting 35V when I have the Start Master On and Start Power set to Cold. See here:

Apologies, I had to scale it down a bit to fit in the 4MB attachment limit, but it should still be readable.

From the manual:

I would think the voltmeter would be showing 35 when TRU1 and TRU2 were selected, but it never goes past ~28V. I tried selecting an engine and hitting Start to see if spinning up an engine would make a difference, and it does not.

This is probably incredibly picayune and I feel bad for even asking, but I ended up down a rabbit hole so here I am.

I did also see TRU1 taking the brunt of the starting power compared to TRU2, I'm not sure if they should have approximately the same load or not.
