Hello Richard,
you are fully right. When disconnecting the battery on an alternator or
generator equipped car the voltage can spike up to double or third or even
more of the 13 Volts, as the voltage regulator would not work anymore without
the battery as a reference. I would suggest only those who can really add good
knowledge should give advice what to do and the others stay silent and listen
to those who know what they are talking about.
To be on the save side the "feeding wire" from the alternator to the battery
should be checked and in case enlarged or a second wire added in parallel. The
wire to the starter solenoid was also mentioned. I do not understand why the
wire to the starter solenoid is of any importance in this case.
I am just wondering, and I am an electronic engineer.

>>I can disconnect my battery and my car will run. Which is a poor

field test for determining if the alternator is charging. So yes the
alternator does supply the system.
Write this down. DO NOT DISCONNECT THE BATTERY ON ANY MODERN ALTERNATOR
EQUIPPED CAR WITH THE ENGINE RUNNING. EVER.
The battery act like a shock absorber in the electrical system. If you pull a
battery cable the voltage can spike upward to 80 or 90 volts. This spike
might just kill one or more of the electronic control units.
Pulling a battery cable can be a very easy way to find out just how expensive
all those electronic control units are.
