[QUOTE="ionbeam, post: 1263561, member: 277"] A hand held volt meter typically can only measure current up to 10 amps, the starter circuit draws 40-60 amps when good and can easily draw >100 amps when bad so the volt meter will be no help for amps. My amp probe measures up to 400 amps and will not be damaged if the current goes over that. When dealing with issues in which the battery is involved the digit after the decimal point is really important. 12.0 vs 12.8 is the difference between a fully charged battery and a battery that is <10% charged.
