AGM or Lead-Acid?

I check for voltage drop and did have .74 Volts between the Battery and the IGN connection on the Voltage regulator.
the drop was in the Ignition switch on the column. Replaced it and now it is .51 Volts
Still testing all the connections between the two points.

One way around that is to add a relay. Break the "run" wire coming into the engine bay, and use the firewall end to trigger a Bosch style relay. Feed the power contact with a fused/ breaker wire off a main point such as the starter relay, and connect the switched contact to the engine bay end of the "run" wire. This will relieve the key of stress, and any drop in there won't matter much

Any drop in either the ground or hot side will ADD to the set point charging voltage. So if the VR is correctly working at 14.2, and you have .74 drop, then it will charge at 14.95

Also that drop can CHANGE (get worse) under some conditions, as the contacts in the key heat up, under load, etc.
