The fuse on the o.v.p. should have B+ at all times,if not check for B+ at terminal 30 (pin 1)of o.v.p. socket.
If you get B+ at the socket but not the fuse the problem is in the o.v.p.. If there is no power at the socket check for bad connections or broken wires at the connector strip on the right strut tower. MF |

WEll - I've been doing my own digging and pulled apart my OVP - in the process I probably ruined it but it is working. I resoldered some of the connections on the back because I wasn't getting voltage to the "idle control valve" at the front side of the fuel distributor. (To check and see if - going on memory here - the OVP is sending out correct information to the "ICV", measure the voltage from the blue w/ red stripe wire - this should read the same as your battery voltage.) I was only seeing around 0.156V here so I took apart the OVP.
To my surprise, it hasn't stalled since - it still isn't running right but a whole lot better than before. The date on my OVP was Feb. 11, 1988 - so 13 years have definately taken their toll. I will let everyone know what other changes I make and see if they help my poor running engine.
