The 99' died on me a couple of times after starting it and shutting it off 4-5 times while working on it. Now it’s started loosing a charge pretty quickly. After an all night charge, I put the volt meter on it and with it running it was at 14.5 volts, turned on the lights, radio, heater, and it stayed about the same, maybe raised a bit, IIRC that means the alternator is doing its thing leaving the battery as the problem. Does that sound about right? It's a WestCo.
