Ok, Sometimes while idleing, the volt meter on my '91 K1500 sways back and forth a little. When starting my truck, the volt meter drops to 10 or 11, and I am pretty sure it should be at about 14 while cranking. When my truck is running, the volt meter is at 14, when I thought it was supposed to be around 12. Going into work this morning, my lights went dim and the volt meter droped to about 11. And a few weeks ago, while sitting at a stop light, my truck almost died for no apparent reason. Maybe I need a new/better ignition coil and or distributor cap and rotor? Or maybe do I have a short some where? Dont know where to start, seeming I have had the truck since November and already had to replace the alternator and starter(This worries me).
I am hopeing that if you have read this far, you can help me fix my baby.
