I am having a problem re-programing my BL F7A. It and my F7B ran great as a consist for years when I decided to give them a rest and stored them in the original boxes for about a year and a half. They both have QSI decoders. Today I took them out of the box and tried to run them. I am using NCE PowerCab and a 5 amp smart booster. The F7B runs fine but the F7A not so good. All sounds are good. However, the A unit did not move when the motor sounds powered up when set at speed step 128. When I change to speed step 28 the unit moved abruptly when the throttle was turned to about 16. I tried to reset cv2 (starting voltage) to 125; max. v.(cv5) to 255; mid speed v.(cv6) to 180; decel. and accel.(cv3,cv4) to 5 and the kick rate (cv116) to 4. After those adjustments it ran better but not like the F7B. I also tried to reset to factory setting which took me back to my original problem.
Would appreciate some help.
Thanks
The starting voltage you cite, if you didn't err, is horrendous. It might translate to something like 6-7 volts just to get underway at a crawl. My QSI-equipped locos, running from Paragon to Blueline, all start moving with CV2 set to 1-4. I wonder if your motor is giving out or if the lubes in the gear have turned to cheese.
I'll check thanks.
Check the cleanliness of the wheels.
