</head><body>I did a voltage check of the power to the OD switch. It was full on. Solenoid kicked in. But intermittently, in 3rd and 4th gear, the solenoid "chattered" between engage and no engage. I have a short somewhere. Will try the relay when it comes in. After that, will rewire and re-solder all connections, replacing the modern two prong fuse unit with a standard glass fuse unit, in case the broken wire is in there somewhere. Stay tuned!<br>Terry Smith, '59 TR3A<br>New Hampshire.<br><br><blockquote type="cite">

I had two intermittent problems that drove me nuts until I could figure one out then diagnose the other. Check the switch wires to see if there’s a problem there.<div><br><div>
