980h boom lowering

Jms670 hey hef. I got another fix this problem that don't act up when your around. Boom won't go down. Intermittently...... Some times 6 hours sometimes 1 some times shutting it off helps sometimes. Sometimes it comes back on it's own. Rain does not effect. Doesn't seem to be bouncing or vibration related. No codes. current to both up and down solenoids is identical. I don't know if its electrical pilot or main control. Any ideas? Was over charging just replaced alternator fixing over...
