19 Volts after PCM replacement
Hi, i have a 1996 jeep grand cherokee limited with the 4.0L. I replaced my PCM with a junkyard unit two weeks ago to fix a no start problem. All was great until five days ago. I was suddenly getting nearly 19 volts ( yes i checked at the battery with a multimeter) when the jeep is running. This caused all of my gauges to go out on the dash. When i do something that draws power, ex turn on lights the guages will flash back on. I replaced my alternator today and it still does it My understanding is that the voltage regulater is in the PCM. Before buying another PCM could it be anything else????
