I did not replace it - the new connections seemed to cure the problem. I know for 86 the 'weather' protection for those relays behind the battery was very poor - in fact the newer design of plastic rain gutter above the OVP/fuel relay etc. includes a rain gutter of sorts to direct the rain away from hitting the relays and running down to the plug/pin area. (I took one from that same wrecked 89 and now it's protecting my repaired connections) Also - this may be risky - but I suppose one could bypass the OVP relay with a wire into the correct pins for test purposes only. If that seems to cure it then sounds like the OVP may be the issue?
