I purchased for my boat engine already comparable voltage indicator (review). Unlike the Multimeter 0.1 V, the charger Imax B6 zero volts. Now you can puzzle over which of the three parts are not precisely when taking the 0.1 V as a benchmark. Not important for me. So clear recommendation, because even at 0.5V you know in common comparative measurement the difference and suggests they plan. One uses it indeed to detect voltage changes. For the purpose of alternator / battery control fully sufficient. Permalink here I had a Youtube address stand-nice guide for cold days: Under Video for "charging circuit Check - Battery & Alternator / Alternator test - Troubleshooting" Search. That's how I understood it today.
20/09/14 Yes, he's still alive ... after 2 weeks of continuous operation, probably lucky. As already written elsewhere: 10.8 to 11.5 V during start-up, from 14.3 to 14.8 V while recharging it. 12.5 to 12.8 V when the battery is full and no additional consumers again.
14:11:14 Works .. It is interesting in this time of year, the open circuit voltage of at light and heating. Under 14 volts times let the friendly check is usually corroded contacts or an old LIMA controller. Or tighten belt (squeaking at the initial start after the start). Commentators
