Voltage Drop Testing

What about an alternator that puts out its normal charging amperage but can't keep your battery fully charged? An often overlooked cause of these kinds of problems is excessive resistance in the high amperage circuit. Loose, corroded or damaged battery cables or ground straps can choke off the normal flow of current in these circuits.

Nasty looking battery terminals that are blooming with corrosion obviously need cleaning. The same goes for battery cables with ends that have been beaten or pried out of shape, or have had the ends replaced. Cranking problems can also be caused by undersized replacement battery cables.

After finding the source of the problem was, as usual, the BECM being "woken up" by spurious radio transmissions, Andy cured the problem by installing a switch so he could turn off the RF receiver at will. He was kind enough to share his story with readers of Rangerovers.net so we can all benefit from his experience. Photo at right: Andy's multimeter registers over an amp of drain with the BECM awake. Problem A brand new battery was unable to turn over the engine after standing for 2 days, any longer and lights, windows etc. did not work, and occasionally there was a completely dead battery. When I used Rangey every day there was no problem. Solution To establish the BeCM activity I used a multi-meter between the battery negative terminal and the negative lead to measure current drain. Photo: Andy's multimeter registers .02 amps (20 mA) with the BECM asleep.
