One problem related to battery cable has been reported for the 1999 Ford Windstar. The most recently reported issues are listed below.
Van purchased used. Okay at first, then without warning the gauges (speed, fuel, tachometer, temperature) would start jumping wildly or top out and stick at max. Happened multiple times. Could sometimes clear by disconnecting and reconnecting battery cables. Have replaced battery twice. Replaced the gauge console. The o/d light (for the transmission) started coming on but does go off when you depress the o/d button - mechanic said that would indicate electrical problem. Now with key in the ignition, won't start but all the gauges jump wildly. You really can't rely on the gauges to be correct - I'm going 120 mph and I'm sitting still! Ford did replace the rear axle that was recalled. I don't know what to expect next. Is there any recall that I missed on the electrical system or a real fix for this problem?.
