Just curious what the typical volt meter reading is:
1) when you're sitting at the stoplight 2) cruising down the boulevard at 3-4000 rpm Trying to see if I'm seeing typical or low readings Thanks I just recently noted a low charging issue that I believe came down to an alternator/voltage regulator mismatch. I was using a Bosch VR with my Motorola alternator. Now I've switched to a Marchal VR and the charging voltages look better. About 13.75 volts while cruising. |

Usually reads about 13.5 volts while driving. I don’t know how accurate the VDO voltmeter is in comparison to the plug in ones (but I do use one in the cigarette lighter socket on my 911.

QUOTE(GeorgeRud @ Jan 18 2020, 11:35 AM)  ...I don’t know how accurate the VDO voltmeter is in comparison to the plug in ones... I measured the VDO voltmeter in my car and found the voltmeter to be within 0.1V in the 8 to 16V range. The real error as we all know is connecting the voltmeter somewhere in the 914 wire loom where voltage drops are common. |
