OK, it's late. Can get pics of gauges in morning if necessary. Will try to explain as best as possible.
Stock '69 300 convertible for the most part. Installed new battery as was unsure of condition of the old battery. The following issues were seen before battery swap. But that's not why I swapped battery. Just want peace of mind with new battery.
OK, here we go. Start car, AMP gauge shows charging, new SW volt gauge shows around 14ish volts at idle. Press brake pedal, volts drop to 13ish, turn on headlights, volts drop to 12ish...all at idle. AMP gauge showing discharge. Give a little gas to raise RPM's...volts go up slighty to maybe just under 13. Go back down to idle....12ish. Let go of brake pedal, volts go up a little, turn off headlights..volts back up to 14ish. Turn signals cause volts to drop alittle. Volts change maybe 1.5 volts as signals go on/off/on etc. Driving around during day...no issues with volts/charging. But as soon as headlights go on, I'm concerned too much 'cruising' and not at higher RPMs will cause my battery to discharge.
I'm researching on here, just curious of causes, or is this normal? Thanks!!
