My S10 pk runs fine but if I park it for 3 days the battery goes dead. Charges back up again in 1/2 hr. Has new battery. Dealership put new body module in but it still has the problem.
something is drawing too much amperage when off. take it back to the dealer and tell them its doing the same thing and was mis diagnosed.
Take the NEGATIVE battery cable OFF. Place a test light between NEGATIVE post and NEGATIVE cable lead. With ignition OFF, see if it lights up (it will) Remove fuses one at a time until light goes out. This will locate which circuit that is drawing current. Usually, it's in the cigar lighter/dome light circuit. Seen it several times on S10's.
Had the same problem. Pulled the power cable from the back of the radio. That fixed the problem. Now working on sorting the source of the parasitic drain.
