Battery Charging
Probably a dumb question but here goes..When you have other things attached to the battery posts like an inverter, battery monitor etc. and then attach a charger to the battery posts or use the conver...

I would rather put the limit at 15 volts because no automotive voltage regulator meaning alternator control is going to top out less than 14 volts unless the alternator warms up and the thermistor within the voltage divider network starts ramping control set point downward. Most Delco and Ford integral regs commonly start out in the 14.2 - 14.4 range at 25c. Motorhomes traveling long distances will arrive at set point limit for hour after hour. Hard to keep the Hatfield chassis batteries satisfied with a house battery diet and verce-visa.
I will give a normal example of Chassis Alternator failure indicator lights on Motorhomes. Roadmaster and Ford(Freightliner and Spartan and Workhorse/chevy do not seem to have this problem). You Start the Engine. You then start the Genset and you have an Inverter/Charger. When the Inverter/Charger goes to BULK charge(over 14.1 volts), during that time it is in Bulk charge the Dash Alternator trouble light will come ON. Once the Bulk charge stops the Light goes out. OR, you just turn the headlamps and Dash AC ON and that amp draw will usually drop the voltage below the 14.2 that is the fault threshold. This is not a real problem but concerns some when they see that red Fault light. Doug
