I have a 98 12 valve. the insterment cluster stoped reading, all the gagues do not redgester. Iam also having a problem keep a charge to the batteries. i volt tested the batteries when i couldn't start in and it read under 11 volts and when i did get it running the volts still stayed the same.i have been able to run the truck back and forth but i notice a slugges start of the start. if you have a answer that would be great. thanks
