madmax Posted November 20, 2010 Share Posted November 20, 2010 Hi: I own a 1989 Comanche, 2.5 with 5 speed. This has been a very reliable, daily driver over the last year. I have even taken this truck on two 1000 mile trips. Anyway, tonight while driving home I experienced a complete shut down of all systems--one minute I was tooling along, lights on, radio blasting, and then suddenly everything shut off in an instant: motor, radio, lights. I coasted to a parking spot and then checked battery cables which seemed secure. There is absolutely no electrical power at all. Is this simply a battery problem? Could it be the ECU?? Please help!!!
