Question about 2001 Chevrolet S-10
I have a 2001 Chevy S-10. The battery light came on and now the truck will not start.
Sounds like the alternator is not charging the battery. if you charge the battery or jump start it does is start?

The vehicle will have a solid state ignition system. Distributor,control unit, pulse generator and ignition coil. The distributor is basically the same as in a conventional (Kettering System) car ignition. The difference is that the capacitor and breaker points are not used. Instead these are replaced by a pulse generator, consisting of a reluctor which rotates with the distributor shaft, a stator and a pick-up-coil mounted on the distributor base plate. There is no contact between the moving parts. The #1 suspect would be the control unit, which is a discrete non-adjustable electronic switching device which determines the period wduring which current will flow in the primary circuit. (i.e. 'The Dwell Angle") The control unit ALSO controls and interrupts the primary circuit when triggered by pulses from the oulse generator. (This induces current to flow in the secondary circuit) Take note that the ignition coil is a special design and should NOT be replaced with a coil from a conventional car ignition system. You should check continuity between all the wiring connections linking the coil, distributor and the control unit. Make sure that earthing points are effective and clean. Check that there is a proper connection between the distributor + and the control unit and esspecially the connections on the coil. Sometimes the vehicle ignition switck can be faulty but it is rare that it is so. The risk is if you do not know what you are doing, you could damage the solid state circuitry in the control unit. Check also the distributor cap, the ignition coil HT lead, see if you can get a spark whilst someone cranks the engine over. The testing procedure is too long to describe here. But email firstname.lastname@example.org for detailed information if you need it.
