Electrical Issues at 2500 RPM (Page 2/2) Gall757 MAY 22, 10:13 AM quote Originally posted by cashmgr: Thanks Everyone for the input. Throughout all of my efforts, turned out to be a bad positive battery cable to the starter (despite it being replaced). New cable installed, all problems resolved and hasn't run better in a long time. Gauges nice and smoothly operating. sometimes it the simple stuff. Thanks to all It's odd that a problem like that would only show itself at 2500 rpm or higher. If it happens again, suspect a bad regulator/alternator or a loose connection. '84s are special, and perhaps this is just another example of why.
