Battery possibily over charging

Post by martin1953 » Mon Jun 19, 2017 11:47 am

After reassembly of 66 W300 318 I have noticed that the battery seems to be pushing out acid from the vent holes. I have not checked voltages at the battery yet but was wondering where to start first. On initial start up each time--ammeter pegs in the charge position and after 15 sec. or so drops back. (possible anternator or voltage regulator issues)??

Thanks for any help

Start by checking every connection and ground from Alternator into dash and back out to battery. :thinking

You can also check the battery. It is possible that "MAYBE" one of the cells could be shorting out and "MAYBE" the alternator is trying to make up for the battery loss. It is just a thought... :thinking

Drops back to center? If so, that's totally normal.
If the ammeter stays at center, or a needle width or so above, the battery is not over charging.

Found the problem to be bad grounding (engine block to voltage reg.) We sometimes tend to over look the simpler things.

Thanks to all who responded.
