I am trying to work out why I lost electrical power last week [all dash dead, and of course no fuel to engine] and it subsequently cured itself.
I am looking at voltage drops. Battery negative terminal to chassis is nothing, so no problem with chassis earth strap.
Voltage at the battery condition indicator is 0.6 lower than across battery [engine running, alternator output 14V],
further 0.6 drop when heater fan is put on high.
So I am looking for the point where the earth wires behind the dash are connected to the chassis, and the point where the heater earth is located.
Thanks.
