Look in Bob Nuckolls writings. Starters pull a lot of amps so even tenths
of an ohm cause volts of drop. The biggest culprits are the connections ,
each one will add a volt or two of drop. I will try and do a bit of
measurement next time I have GKWhip home for tinkering. (Soon, the EFIS is
about to be installed)
