I have setup the solenoid exactly as the A/T led light but the issue is that the solenoid doesn't stay up. I need to try 3-4 times for it to stay up.

So i am thinking that this is a timing problem.

The A/T switch uses 38001 (>K:ROTOR_BRAKE) to toggle the A/T and it works.

Both the A/T light and the solenoid use (L:switch_3801_73X, number) 0 >

I think that maybe i need a delay in order for the solenoid to understand that the switch is on?

Am i making any sense?

PFP3N has a solenoid switch? You probably mean PAP3.

#

I would suspect the switch is not getting enough current for the solenoid to keep the switch lever in position.

yes PAP3N.... I feel stupid now... I think the solution was to just hold the A/T switch around 0.5 a second more in order to uinderstand that the A/T in the sim is on in order to hold 🙂 proably if i increase the update the config execution slider 🙂

You can close this.
