Hi, '67 520 just put a new interstate in and all was well for a few weeks.
Noticed the battery was venting and checked the fluid levels.
Battery had cooked down so added some distilled H2O.
Checked voltage while running and the it stayed constant @13.9DCV.
Installed a new regulator and now the voltage climbs to 14.9 when reved up.
Cleaned all the connectors with caig deoxit.
The battery is @13.5 when the truck is not running.
Please advise further troubleshooting.
Thanks in advance for your time and attention, Bill Berndt
