B98 - DE6 dynamic brakes not working

[Geo]

With the new update the dynamic breaks on the DE6 are not working. The Ammeter and sound act as expected but there is no braking action

The patch notes mention "Rheostatic dynamic brake power now peaks at around 35 km/h". The braking effect (for the given current draw) used to be much higher at high speeds than it apparently should be, perhaps it is working but less than you were used to

You raised a good but - Just tried again - it doesn't seem like it's working - if I see 6 on the ammeter left side I expect braking to be about the same as acceleration 6 - but there is no noticeable breaking action.
Do you normally use dynamic brakes and they are still working for you?

I'm not sure that's necessarily true, but in any case in my test running light down a hill the dynamic brakes definitely slow a DE6

Dynamic braking effort depends on two things - armature current (which ammeter displays) and excitation (which isn't shown anywhere). At low speeds braking is limited by maximum excitation; above 35 km/h the magnetic field has to be reduced to prevent overcurrent, which also brings braking force dawn.

Thank you all for the comments here (and Altfuture for the comment in the main thread):
Got it fixed:
I had a hunch that something was not quite right after the update: I was in a DE6 that was running before the update and I didn't get any Dynamic Braking at all. So I fast traveled to the Harbor - grabbed another DE6 - and Dynamic Braking is working just as expected in the update now.

Lesson learned: Even if the game state doesn't reset with an update it may be a good Idea to start with a fresh engine that wasn't running before the update....

Now on to more hours of blissful railroading
