3070 loosing functions intermittently

Hello: A friend of mine is working on a MF 3070 that will loose PTO,high/low or diff lock intermittently. It will not loose them all at the same time, but randomly. Example; work tractor for a while, PTO quits. Shut tractor down, come back later, PTO will work, then High/low may give up. Thinking its a controller issue, not hydraulic. Any thoughts? 3120 etc were new when I last worked on MFs. Thanks in advance, Bob
 
I have an MF 3090 - have had the same problem in the past. Dealer told me to clean the electrical connections at the battery. If they are corroded, you're not getting enough electricity to run these functions because they are electric over hydraulic. Hope this helps.
