Seems normal to me. A new battery is never fully charged out of the box and it's sucking all the current it can from the alternator, causing a 0.4 volt drop across the cable, engine, ground strap and body.

what does the collected wisom recommend .. on an 85 vanagon .. when there is 13.8 volts of charging ooomph at the alternator main terminal ... and only 13.4 at the ( new ) battery . I look for at least 13.8 volts at the battery. 13.4 is low in my opinion. ( I like to see 14 something at the battery actually ) alternator appears to be a fairly fresh Bosch rebuilt. The van's always started ..especially with the old somewhat worn 1.9. ( manual trans ) ... on my own 85 Adventurewagon I got at least a half volt more to the battery with redundant batt cables added. I don't want to do that to this van. the 85 Vanagon has the last year of the 'small' battery to starter cable of course . 86 is considerably fatter. trans ground cale looks good ..though I didn't take it apart. I'll post another note regarding stater. thanks ! S,. _____ No virus found in this message. Checked by AVG - www.avg.com Version: 10.0.1204 / Virus Database: 1497/3505 - Release Date: 03/13/11 |
