XJ voltage drop, 14.3 to 11.8 then to 0.0 in a few seconds, STUCK 100 mi from home...
My XJ has a voltage drop, 14.3 to 11.8 then to 0.0 at every start within a few seconds. I have a new battery, even swapped it with another one, not the problem. Also have a new ZJ alternator (upgrade that replaced the XJ one) with 136 amps and its doing the exact same thing as when this problem started a few days back. any ideas? What controls the voltage from the alt. to the battery? Does the regulator signal from the ECU or ECM? I shut it off & it does the same thing over & over. Not to mention I'm 100 miles from home working outside. Thanks, Dean
