Early 5220 (no neutral on shuttle) keeps blowing 4th speed powershift fuse. #28 in the panel 5 amp. I've disconnected each solenoid and pressure switch and ohmed them out and can't see any abnormal numbers. I'm getting close to sticking a 30 amp in it and look for smoke. At least then I would know what to work on.
Well......AFTER ohming out the pressure switches and solenoids and not finding anything out of line.... I discovered the 4th speed clutch pack fuse was blown. Changed it out and problem solved. But.....now I wonder what caused it to blow??
Thanks for everyone's help!
Early 5220 without neutral on the shuttle. Lost 4th on the powershift. 1,2,&3 work normal. Shift to 4th and it stops. Light flashes 5 times. Changed 4th speed pressure switch and nothing changed. Advice appreciated.
