OK last night my jeep's headlights kept dimming, radio shutting on and off, and power to the motor would be lost for a split second, only to immediately come back on. Shut engine down and it would not restart but the electrical system was going hay wire!!
It's a 4.0 96 XJ AW4. All grounds are excellent.
I have a Blue Top deep cycle Optima battery that's 3 years and 4 months old.
I jumped the jeep this afternoon with my truck and it'll start right up and stay running, although the headlights randomly get dim and then bright again. Put a multimeter on the battery w/ the jeep running and it shows 14 volts.
Turn the jeep off and it wont restart. Multimeter back on the battery and it reads less than 9.5 volts.
Am I correct in assuming my battery went bad??
