Good Battery / No Lights / Nothing
89 Cherokee 4.0 Auto A/C no mods 235K miles-
Saturday night my son (12) left ignition key on when getting a cd out of the radio. Sunday I jumped vehicle to use the jeep, did so successfully and it ran for 20 - 30 minutes, then while idling just quit.
I thought perhaps not charging and running it drained the jump charge.
I set up a trickle charge and left it on for 10 hours.
Tried to start nothing.
Put on the higher rate charge, still nothing.
Finally tested the battery full 13.8 volts. Still no lights / etc.
Going out to clean terminals.
