Please fill out the following to ask a question. MAKE: GMC MODEL:Sierra YEAR: 1994 MILES: 194K ENGINE: 350 DESCRIBE ISSUE....Just bought this truck. It had been sitting for a while, and not being driven. When I test drove it on Tuesday, it cranked pretty slow, but started. Test drive was fine. Drove it home (60 miles) yesterday. Figured the battery just needed to charge up while driving it. When I got home, it still cranked slow before starting. The battery reads 12.48V with key off, 14.06V with engine running, and 13.77V with a load (blower on high, lights on). Alternator reads 14.19V with engine running and 14.09V with a load. Are these readings good or is something amiss?
