Remember These Points:
Amperage produced by a vehicle charging system is high
enough to cause severe personal injury
check the V-belt. If it slips, you can get false voltmeter and
ammeter readings (tighten if necessary)
Before doing any test on a vehicle charging system, start
and run engine to warm it up and smooth out the system. Ten to
fifteen minutes at 1000 to 1200 rpm should do
Before connecting generator or regulator adapter, remove
battery ground cable to keep from causing a short and further
damaging system. Always remove negative battery terminal
from battery post first and always reconnect last
Never let a hot wire flop and strike any metal part of vehicle.
This includes flashing to test for a hot wire
