I popped into Jaycar during the week and purchased one of those cigarette lighter battery meters. Put it in my Holden Rodeo and when turning the ignition I was getting a voltage of 12.6/ 12.7 and when the car was running 13.9 to 14.2.
So then I transferred it to the Defender and as previous posts tells you I have just finishing charging both batteries with my Projecta. On the starter battery the Redarc solenoid LED light glowed for five days after. When I turned the ignition on the defender it showed a reading of 11.5. Is there an explanation of why it could be reading so low at the cigarette lighter when the battery is fully charged? When running it showed 13.8 to 14.
