Question about 1987 GMC V2500
I bought 1989 GMC 2500 Van. Drove 500 miles in snow and sleet using lights, wipers, heater and had no problem at all. Noticed guage started showing negative charge when running then all of a sudden it would jump over too charge. I have had alternator checked as well as battery and no problems are found. I ran Van for another week and noticed everything seemed to be ok but last night it was cold and I started Van up and proceeded to travel about 10 miles home. Van showed a negative charge on guage and I had to use headlights to travel at midnight. I got about 8 miles then it just lost electrical power and died out. My husband came and as soon as he touched cables to battery it started right up. Showed charge all the way home but when I started it this morning it immediately began to show discharge. I am afraid to drive it and don't wish to stall again or be unable to start it after shutting it off. Can it be a bad battery? Alternator?
You need to Check the Belts for Tightness and replace the Battery Cables. When you Replace the Cables, you will need to Grind the Area where the Cables attach to Make sure that they are Contacting the Area Completely. A wire Brush will work very well for this. If the Belts are worn, they will Stretch out and will not allow the Alternator to charge the Battery. If you need more Help Just let me Know! Please Rate My Response! Thanks!
