Hey guys!

My name is Lucian, I've been working with CG260/16 engines for 3 years, I'm having a problem with one of the pieces of equipment, power and temperature fluctuations, we've already carried out several tests and inspections on components:
1) Gas mixer
2) Wastegate/actuator
3) throttle valve
4) ignition timing
5) ignition module
6) DZR Actuator
7) Deif control generator

The generator is controlled by Deif AGC4, where we have already carried out tests on the cables and signal 4 to 20, has anyone experienced this problem, or would you have any recommendations? I will attach the file for those who have the Jview software, the equipment file is in operation with a fixed load of 75%, when equipment has this load share, the variation is much greater. Thank you in advance for your help.
